Spanish language serial vandal

Administrators might want to have a look at Creating quite a bit of clean-up and not a single productive edit as far as I can tell. Moebeus (talk) 13:04, 4 March 2020 (UTC)

Suspended, deleted and deactivated website accounts

I noticed items Q49776568, Q65684169 and deactivated account (Q56631052) which are intended to be used as a reason for deprecation. However, I can't see a situation where any of these are a valid reason for deprecation. If the account was accurate, then instead end time (P582) should be used as per Help:Deprecation.

Would it be acceptable to re-purpose these items to represent the general concept of a deleted/deactivated/suspended account and instead use them with has quality (P1552)? --SilentSpike (talk) 14:08, 1 March 2020 (UTC)

Alternatively, perhaps a new qualifier "account status" is needed to make this information clearer? --SilentSpike (talk) 14:09, 1 March 2020 (UTC)

Property proposals for PoS blockchain cryptocurrencies

Hi, I recently discovered that while PoW currencies like Bitcoin are reasonably describable using our existing properties, I found that more were needed to accurately model PoS coins. I went ahead an created a series of property proposals. You are very welcome to comment on them and support those you like. Thanks in advance.--So9q (talk) 16:07, 1 March 2020 (UTC)

The property proposals page are quite full. This might take a while. --Trade (talk) 17:44, 1 March 2020 (UTC)

Importing movie box office data of a single small distributor into wikidata

Hi! I was discussing this on my home wiki (huwiki) and I was advised to ask for your opinion. There is a small Hungarian indie movie distributor Mozinet who regularly publish the box office and attendance data for the films they distribute on their website. For Hungary, this is a niche market and most of these data don't make it to the big box office reviews of other sources. to be able to use this as a source/reference for articles in huwiki, the page at needs to be archived since they refresh the data weekly. The issue is that they publish the data in Google Docs, which or other archiving pages are not able to handle properly (tabs...). The question is:

  • is it okay to use something like Openrefine to import the csv
  • and if so, what kind of structure do you recommend to use?

I believe that copyright-wise this database qualifies as spin-off, so the data would be okay to copy.

If the above cannot work, would you be able to advise for a solution?

Thank you in advance Teemeah (talk) 09:19, 2 March 2020 (UTC)

  • Have you tried to engage them and ask them to publish the data in a format that can actually archive? It seems to me like it should be in their interest to have people engage with their data and their current solution is likely not intentional. ChristianKl❫ 18:46, 2 March 2020 (UTC)
@ChristianKl: It's a two person company, unlikely they will invest in finding another way of publishing the data just for our sake. (Not by chance they use free Google Docs for that). Especially that they would have to regularly be able to update that, hence the Google Doc solution, without having to pay a webmaster to do that work every week.

Wikidata weekly summary #405

interwiki to/from the Incubator

A quick question: would it be okay to add interwikis like this: [[hu:incubator:Wn/hu/Luxemburg ingyenessé tette a tömegközlekedést]] to Q86746352, i.e. in the case of Hungarian, pointing to the Incubator? - Xbspiro (talk) 20:00, 2 March 2020 (UTC)

FreeDB closing again Altho its functionality has been mostly replaced by Musicbrainz and we have several properties to capture their database info, this is still of interest to those of us who care about free data. —Justin (koavf)TCM 01:14, 3 March 2020 (UTC)

innocent user blocked, compared to somebody he is not, now real name is all over internet, damage is irreversible

ENTIRE wikimedia, wmf, WMFOoffice refused to look into this; it's also on twitter, on meta when reported, it's reverted, nowhere to go to report; wikidata chat seems like the best place for it; have senior administrator confirm this!Forcedmoves (talk) 23:51, 9 March 2020 (UTC)

If your personal information have been leaked you should email an admin instead of writing on the project chat for all to see. Alternatively, join the IRC channel and let us solve this. --Trade (talk) 23:58, 9 March 2020 (UTC) for all to see is correct because this is huge problem in real life and in real life everybody did see; this is a huge problem started by antandrus (david real name, andrew hayes fake) in support with partner in crime bsadowski1; others are dannyS712, vermont, nigos, praxidicae, achim55, ~riley, majora, masumrezarock100, schiggendiller, tegel, hasley, XXblackburnXx etc... but the main culprit who started it all is antandrus and he thinks he is wmf's detective who has to do this job, going after ljupco and even his sick, old mother then there are all of the simple wikipedoia administrators like chenzw who also messcarades as djsasso; the innocent user's name is ljupco and is accused of being projects user but nobody cared about it and thus this will not be resolved in a calm manner as this is huge problem in real life, antandrus even used police and false police reports to go after ljupco, this problem goes back to 2005: antandrus is persona non grota everywhere, as proven:

antandrus, with WMFOffice's blessings using police as his illegal strategy to terrorize the innnocent:

"trusted users" conversation was about antandrus majora aka ma-HO-ra removed:

because of antandrus stevenJ81 is gone from wikimedia forever as proven:!topic/wikimediacomputer/aBsS0Pv2OqQ!topic/wikimediacomputer the ironic thing is that ljupco is guilty by mere association, yet wmf banned him but that is insane, that is perfect example of wikihypocrisy because he simply knows the culrpit for many decades but so what, kill the father for the sins of his son and vice-versa?

what is the link to open irc channel, is it wikimedia's only? but damage has been done; it's irreversible; if you only knew how much...

case in point: they say 'it's good idea' to report this to meta and it was done no doubt million times, just to be deleted SHOWING IGNORANCE HOW WIKIMEDIA IS PURELY GOVERNED BY THE LAW OF THE JUNGLE!!! 00:23, 10 March 2020 (UTC)

The greyish spaces that appear in the left part of each statement on a given item are usually quite empty for they contain nothing more than the name of the property used by that statement, while the white spaces to their right has to fit in things that use much space – values, qualifiers and references, and possibly more than one of each. In that context, and because I sometimes feel that Wikidata is a bit visually dull, I wonder if someone could develop a little – otherwise useless – gadget that would display as a small image under the property name the value of logo image (P154) in the item of the value of the subject item of this property (P1629) statement of the given property. In other words, on the Aaron Blake (Q86957440) item, the The Washington Post contributor ID (P7943) statement would display File:The Logo of The Washington Post Newspaper.svg under 'The Washington Post contributor ID', for instance, because The Washington Post contributor ID (P7943) has The Washington Post (Q166032) as its subject item of this property (P1629) value and The Washington Post (Q166032) has File:The Logo of The Washington Post Newspaper.svg as its logo image (P154) value. Get it? It would pimp our items a little bit! Mostly in the 'Identifiers' section, I believe, which is actually nice, for that section does not get to display image (P18) and its subproperties. Maybe it would also help navigate faster through the longest lists of statements. Thierry Caro (talk) 10:09, 3 March 2020 (UTC)

I think it's frivolous and unnecessary. Wikidata is not meant to "look good" like an article. It's primarily a repository for machine-readable data, some of which gets digested and regurgitated by infoboxes and other outlets. The slap-dash hodge-podge of items, properties and qualifiers need not be grammatically correct, nor aesthetically pleasing. -Animalparty (talk) 03:01, 4 March 2020 (UTC)

Fate of Wikidata:Contribute/Suggested and open tasks

90% of edits to the page are vandalism but it hasn't changed much since its introduction. A link to it is in every status update issue, so it probably deserves an update and regular care. (Counterpart on the English Wikipedia.) --Matěj Suchánek (talk) 10:54, 3 March 2020 (UTC)

How to check consensus before changing a property?

I want to add constraints to UN/LOCODE (P1937) so it can only be used on instance of (P31) city (Q515). Should I just go and do it? Should I seek consensus somehow? If so where? Iwan.Aucamp (talk) 19:00, 3 March 2020 (UTC)

Is there any indication at that it is restricted to cities? If so, is the definition of city used for locode absolutely compatible with every other authority's idea of what is & is not a city. If you have any doubt about either of these things - and you should - then you should think again about your constraint. In general, you're best off announcing your intention on the talk page for the property & seeing if anyone has anything to say. --Tagishsimon (talk) 19:09, 3 March 2020 (UTC)
Oh look: mostly not cities: ... /why/ do you want to restrict a code system that applies much more widely than cities, to cities? --Tagishsimon (talk) 20:37, 3 March 2020 (UTC)

Date of baptism/religion

When was the following alert added: "An entity with date of baptism in early childhood should also have a statement religion." Seems like a really bad idea. After all the religion that someone was baptised in as a baby may not be the one they espouse as an adult, and currently there is a standard that Religion should have at least two references, so it seems like there should be a degree of caution about urging people to add more Religion statements. Levana Taylor (talk) 02:30, 1 March 2020 (UTC)

I don't really see this as a problem: that is the religion at that time. —Justin (koavf)TCM 03:04, 1 March 2020 (UTC)
You are baptized into a religion, so yes, you should add the religion you are baptized into. If the religion changes you can add a start and end date. --RAN (talk) 04:46, 1 March 2020 (UTC)
There's no standard that you need two references for religion (P140). "In particular properties that are instance of (P31) property likely to be challenged (Q44597997) should be supported by suitable references when applied to living people." talks about plural when talking about properties and a plural of references because it talks about multiple properties. ChristianKl❫ 10:50, 1 March 2020 (UTC)
point in time (P585) could be used as a qualifier on religion, or (for more accuracy) the constraint should be changed to say religion should be used as a qualifier of date of baptism in early childhood (P1636). Peter James (talk) 14:00, 1 March 2020 (UTC)
Now, with that last part, I agree. Definitely it would be good to state what religion that baptism was as a qualifier. But I am still reluctant to think that that baptism should be used as a Religion statement, not, at any rate, unless you also know something about the person's adult religion & can set an end date to their baptismal religion if they no longer followed it. Otherwise, you are at risk of letting unwarranted assumptions be made about a person -- should never assume their baptismal religion was their adult religion. Levana Taylor (talk) 05:41, 2 March 2020 (UTC)
If I remember correctly, there were periods in UK history (in the 17th century?) when parents were obliged to have children baptised in their local parish church (and even attend regularly?), even if they did not subscribe to the Anglican religious denomination (eg Quakers, Catholics, other non-conformists?). So it may be that religious denomination (as a main statement) cannot necessarily be deduced from a baptism record, even for the point of time of the baptism, without additional evidence. On the other hand, noting the denomination as a qualifier for the baptism statement seems harmless; though I am not sure I would go so far as to make it a requirement Jheald (talk) 12:40, 4 March 2020 (UTC)
  • The property is mostly relevant when the date of birth can't be found. If the date is referenced, I'd expect it to include a church's registry. --- Jura 10:20, 4 March 2020 (UTC)

Error saving wikipedia link

I've been trying to link Q86927133 to en:Patricia Morgan (transgender woman), but all my attempts to make this happen have so far failed. Is there some problem I'm not aware of here? -- The Anome (talk) 22:28, 2 March 2020 (UTC)

@The Anome: Yes, the problem was that that the link was already included in an already existing, duplicate item (Patricia Morgan (Q86926980)). I have merged them and will perform any needed cleanup. Thanks for asking! --Kostas20142 (talk) 22:36, 2 March 2020 (UTC)

Thank you! Unfortunately the error message was completely uninformative: I should have checked for another version earlier. -- The Anome (talk) 22:40, 2 March 2020 (UTC)
@The Anome: Did you receive the error message: Could not save due to an error. The save has failed.? I know, it isn't the most informative messsage ever. However for future reference keep in mind that a common cause of this message is exactly this situation, the link already existing in another item. Either ways no worries, and thanks for finding this duplicate! --Kostas20142 (talk) 22:47, 2 March 2020 (UTC)
Yes, that was the message. I was sure I did a check first, but I think what must have happened was I was outraced by a bot which created the Wikidata item almost immediately after I created the Wikipedia article, and before I tried to make the item. -- The Anome (talk) 22:55, 2 March 2020 (UTC)
If that is the common cause, shouldn't we change the error message? - Jmabel (talk) 00:21, 3 March 2020 (UTC)
I think it is bad practice for a bot to create a new Wikidata item immediately (in this case 45 minutes) after the creation of Wikipedia article. In many cases there may already be an item for the subject, or, as here, the creator of the article will create the item themselves. The bot should have waited. It seems this have given problems before according to the bot permission --Dipsacus fullonum (talk) 07:05, 3 March 2020 (UTC)
The message looks like a combination of MediaWiki:Wikibase-error-save-generic and MediaWiki:Wikibase-api-failed-save. Peter James (talk) 15:40, 3 March 2020 (UTC)
It also happened to me when moving sitelinks at a time of high WD load. Often then the original link is deleted but the new one is not created. This was claimed to having been fixed but it still happens. --SCIdude (talk) 17:01, 3 March 2020 (UTC)

What wikidata project should I contact for queries regarding UN/LOCODE (P1937)? Should there not be some property assigned to properties to link them to wikiprojects?

I want to clarify the use of UN/LOCODE (P1937) but I don't know what project owns the property or who to ping in the question. Is there some simple way to find the project that owns the property? Could such a relation not be captured in the property itself? Iwan.Aucamp (talk) 15:48, 3 March 2020 (UTC)

There is maintained by WikiProject (P6104) just for this purpose, and I agree that it should be used more often. --SCIdude (talk) 07:18, 4 March 2020 (UTC)

Create Forms


at the moment I think about how Wikidata can be made more userfriendly for people who are not so deep in the structures of Wikidata. I think forms are a way to create items easier and with the structure as needed for that. A tool to create forms is Cradle. In Cradle it is possible since a few weeks as far as I know to see the properties in the language of the user inferface. So it is now easy to use it also for people who speak another language. I for myself do not know all English Labels of the Properties and so this is very helpful. I think it were great if some of you would create forms for topics where the structure of the items is clear. I think this is helpful. After there are a lot of things who dont have a clear structure a page where the structures how the items should look like are documentated in a way what is easy to understand would be helpful. --Hogü-456 (talk) 20:20, 3 March 2020 (UTC)

@Jmabel: Cradle is a Tool. So as far as I know this is independent of the settings for the language in Wikidata. From my point of view the change in Cradle improved the possibilities to create items. -- Hogü-456 (talk) 20:55, 3 March 2020 (UTC)
  • If there are fields that you think could benefit from a form, you could ask at the relevant WikiProject. --- Jura 10:12, 4 March 2020 (UTC)

B. J. Elder: duplicate items

Hello! Items Q86837071 (B. J. Elder) and Q3631677 (B.J. Elder) are about the same person. The second one (Q3631677) was already present, while the first was automatically created when I created the corresponding article on (here). These items should be unified – also, the second item includes a categorization of Elder as a volleyball player, for unknown reasons, and cites a wrong birthdate.

Please help with this week's error list

Please help with this week's error list at Wikidata:Database reports/items with P569 greater than P570, the Peerage has many errors, either just wrong at their site, or people with similar names conflated or just completely wrong people combined by human error. --RAN (talk) 13:44, 5 March 2020 (UTC)

I have noticed that one the many problems and headaches caused by The Peerage import is that, on rare occasions, birth & death dates seem to get conflated if an item is a redirect to another on a Wikipedia. Like if an unremarkable son on en-Wikipedia is a redirect to his famous father, the vital dates of the father may be applied to the son, or vice versa. I have not investigated this closely, but it's something to watch out for. -Animalparty (talk) 21:47, 5 March 2020 (UTC)
Is there someone at the Peerage that we report errors on their side to? Or do we have a page setup to keep track of errors from their side, like we do for VIAF? --RAN (talk) 05:08, 6 March 2020 (UTC)
It looks like there has been more than one import. Sometimes names and dates may be corrected, but they also have pages with warnings saying that they are under construction and probably contain errors, and these have been used as sources, both in the import and in Mix'n'match, which seems to be older data. Also when the site removes an entry the same identifier may be used for a different person, so Isabella Fane (Q76213523) is "named as Charles Roger Lupton" because #609239 was previously a conflation of Charles Lupton (Q5080395) and Dr. Charles Athelstane Lupton (Q75864909) - I don't know if this only applies to "under construction" pages, or to all pages. Peter James (talk) 11:16, 6 March 2020 (UTC)
There is only about 100 current errors but that is using the detection method of people who died before they were born. I am sure there are more subtle errors. --RAN (talk) 21:56, 6 March 2020 (UTC)
@Richard Arthur Norton (1958- ): Worth noting that if you make very poor decisions when "correcting" data, as you did here when you presumed that the DoB and DoD were transposed (in fact the problem was an erroneous DoB by 1 century), then you just make things worse. --Tagishsimon (talk) 22:08, 6 March 2020 (UTC)
  • I have corrected over 1,000 of these errors and occasionally I will make a mistake, so there is really no need for the sarcastic tone and the scare quotes with "you make very poor decisions when 'correcting' data." That is 999 errors corrected and one error transformed into another error. No data set is error free and correcting errors can introduce new errors, that is just how information theory works. --RAN (talk) 22:23, 6 March 2020 (UTC)
It suggests you're working on the basis of your assumptions, rather than checking the data against sources. That will not end well. --Tagishsimon (talk) 22:31, 6 March 2020 (UTC)

Suggested metrology properties: "quantity symbol" and "unit of measurement"

Hello. Physical quantities and units are an important aspect of scientific communication as they are the means to represent quantitative results. As a simple example, the physical quantity force, with quantity symbol , can be defined by the formula , with mass and acceleration . The number of physical (and chemical, biological, ...) quantities is in principle unlimited, because any relation between quantities gives rise to new ones. Having one item for each quantity mentioned in the literature - with label and description in each language - with sufficient information to determine with certainty which quantity the item represents, will help with the unambiguous communication across language barriers in the scientific context.

Take for instance the quantities luminous flux, luminous intensity, luminance, illuminance, ... Those are all quantities related to light, but each has their own, distinct definition. They have "radiant ..." counterparts, covering more than just the visible spectrum of light. Properties that are important for correctly identifying a quantity include a formula, the quantity dimension, the quantity symbol and the unit of measurement. The representation of the latter two in Wikidata is currently suboptimal, in my opinion.

I'm writing to encourage people interested in metrology and science to participate in the discussion and creation of the following two properties:

(The latter has one "oppose", but since then I have extended the motivation based on literature research and my experience so far in improving quantities and units in Wikidata.)

Thanks. Toni 001 (talk) 09:52, 6 March 2020 (UTC)

Storage space for WikiBase sandbox


I'm with a large U.S. university library and we are looking to set up a WikiBase instance for experimentation. We are currently assessing hardware and software requirements. Thanks to the excellent and simple documentation on the WikiBase site, we are aware that we will need a minimum of 4GB of RAM and 6GB of disk space for an for an empty base.

However, what are the recommendations for a sizeable sandbox? We know of several initiatives in the US and in Europe that have experimented and even adopted WikiBase but we cannot determine their storage specs. Any idea on what these might be? Even better, is there a rough estimate of the storage reqs for record anyone can provide? Thanks in advance for any advice.

Kindly, Digitalibrarian

Wikidata with close to 100 million items seems to have a total of about 1.5 TB of changes since it started, based on this graph. From this email. the RDF dump for Wikidata (as of almost a year ago) is about 350 GB. That suggests sizes around 10-20 kB per item; presumably you need a small multiple of that to have things run comfortably. ArthurPSmith (talk) 17:55, 6 March 2020 (UTC)
Given how cheap drives are these days, those numbers are effectively tiny. - Jmabel (talk) 19:10, 6 March 2020 (UTC)

Open sourcing "wiki-slurpee" a tool for scraping data from google

Awhile back I posted here about a browser extension I was working on for scraping Google's knowledge graph data into Wikidata. Now it's open source and available.

Feel free to use it, contribute to it or request features.

Can you add a Google Knowledge Graph ID (P2671) qualifier to the references? It is otherwise pretty difficult to verify your edits. —MisterSynergy (talk) 20:19, 6 March 2020 (UTC)
@MisterSynergy: sure, I can do it like this but it seems that's not possible to do for freebase ids (it yells at me when I try to add a Freebase ID (P646) to a reference). But for now at least I am already adding the freebase/gkg ids as a primary property. BrokenSegue (talk) 20:42, 6 March 2020 (UTC)
More like this, I guess. Your inital example does not include a Google Knowledge Graph ID (P2671) statement, thus I'm asking. Anyways, it would be great if you could add complete references (at least stated in (P248), external-id property, retrieved (P813)) to all statements which you add.

Wikiproject for error detection and tracking

Is there a Wikiproject that concentrates on error detection and tracking? I want to group all the error detection searches in one place and have one place that tracks all the lists of errors that need to be corrected at the source, and who to contact at the source. We have searches for people with the same first and last name, people who died before they were born. Dopplegangers that need to be merged and a few other error detectors. If there isn't one already I will create one. --RAN (talk) 21:59, 6 March 2020 (UTC)

Please fix format constraint of P3088

See Q15439309, it seems that the ID of P3088 alowed the format "Kew-\d{5}". --Koala0090 (talk) 01:58, 6 March 2020 (UTC)

It seems to be the correct ID. If there is only this one, it should probably be added as an exception to the constraint. If there are many more, a change to the constraint would be better. Peter James (talk) 17:28, 6 March 2020 (UTC)

entry for one thing or another?

What's the right way to handle a Wikipedia article that basically refers to one of two different things, ambiguously?

The English Wikipedia article Calorie refers to either the "physics" calorie or the "food" calorie (= 1000 physics calories). That ambiguity is reflected in the label of the corresponding entity here, calorie (Q130964), which says "unit of energy with different values".

But Q130964 is trying to be two things at once. Its description says, and it's tied to a Wikipedia article that says, that we might be talking about one thing or the other. But most/all of the rest of the claims at Q130964 are clearly talking specifically about the "physics" calorie -- that is, the rest of the entity is not something with "different values", it's trying to talk about just one. And clearly we ought to have distinct entities that each unambiguously talk about exactly one kind of calorie.

So I believe we need three different entities:

  1. one describing the "physics" calorie
  2. one describing the "food" calorie (this is clearly already kilocalorie (Q26708069))
  3. one disambiguating between the two, which can be properly tied to w:Calorie.

It's probably safest for (1) to remain Q130964, and for (3) to be a new entity, and for the w:Calorie sitelink (and some/all of the other sitelinks) to be removed from Q130964, and attached to the new entity. I suspect there are existing entities linking to Q130964 as the "physics" calorie, but I don't know how to track them down. I suspect there are few if any existing entities linking to Q130964 as a deliberately ambiguous item.

What I don't know is how to link (3) to (1) and (2). I could give it two different from (P1889) claims, but that's not quite right, because it's more the same as them than it's different from them. I could give it two has part (P527) claims, but that's not quite right, either. Really I want a property that says "One of the things this ambiguous name might refer to is...", but I don't think we have (nor am I suggesting we add) that strangely specific property. But do we have anything that's close?

(Note, by the way, that there's actually another sort of disambiguating entity lurking in the wings here, Calorie (Q16768157), but that's clearly a different animal, not usable for (1), (2), or (3).)

This situation is similar to (but not really the same as) the "Bonnie and Clyde" problem, I guess. (It's sort of "Bonnie or Clyde".) —Scs (talk) 18:03, 6 March 2020 (UTC)

Maybe use Wikipedia article covering multiple topics (Q21484471) for the mixed up Wikipedia article which isn't a disambiguation? Ghouston (talk) 02:12, 7 March 2020 (UTC)
Aha! Or maybe even Wikimedia page relating two or more distinct concepts (Q37152856). Thanks. —Scs (talk) 03:32, 7 March 2020 (UTC)
Hmm, do we really need two such items? Ghouston (talk) 03:51, 7 March 2020 (UTC)
I wouldn't have thought so, and I'm hard-pressed to see the distinction between them. A quick check shows we have 263 instances of Q21484471, and just 16 instances of Q37152856. Some of them, at least, should probably be moved to Wikimedia disambiguation page (Q4167410), for example Q83875275 and Q84085731). —Scs (talk) 12:25, 7 March 2020 (UTC)

I'm not sure, but pinging @Hannolans: who's one of the masterminds behind Help:Copyrights. Cheers, SandraF (WMF) (talk) 09:15, 7 March 2020 (UTC)
We have countries with 70 years pma or longer (Q60845045) and countries with 70 years pma or shorter (Q59542795), and this is for the 50 years. We need longer and shorter to qualify copyright status as a creator (P7763). longer is used for copyright protected status, shorter for public domain status. 50 years pma or longer could also be Berne Union (Q72970347). Not sure what is better. Another point: I'm not sure if the 'and longer' and 'and shorter' are good concepts to create copyright status lists per legislation. Probably we could better write as jurisdiction two values in the qualifier, or two values for the property: 'countries with 50 pma' and 'countries with 70 pma' and 'US'?

what's wrong with this query?

JPEG (Q2195) is an instance of Wikipedia article covering multiple topics (Q21484471). (In fact it's the model entry for that class.) But the query

SELECT ?id ?idLabel WHERE {
	?id wdt:P31 wd:Q21484471
	SERVICE wikibase:label {

@Scs: That'll be to do with statement ranks on the various P31 values. Conflation is marked as preferred, meaning it will be the only response to a wdt: query. (see also this.) Try:
SELECT ?id ?idLabel WHERE {
	?id p:P31 [ps:P31 wd:Q21484471] .

Oh! Wow. Thanks. I shall have to study this. (I confess I don't really understand that syntax p:P31 [ps:P31 wd:Q21484471].)
Actually, I guess I need to learn more about "rank" in general.

@Scs: I've recycled a couple of talk page responses, dealing with qualifiers and references, and truthy/non-truthy statements, which might help you understand both the weird syntax, and the absence & means of finding Q2195, at User:Tagishsimon/WDQS. Meanwhile Wikidata:Request a query is probably the best place to bring WDQS questions. hth --Tagishsimon (talk) 15:28, 7 March 2020 (UTC)
@Tagishsimon: Thanks, and Wow again.
I'm reminded of the old story about the blind men and an elephant (Q1218005). You've got this nice explanation (which I do hope to wrap my head around) of the rather complicated situation from the perspective of RDF and SPARQL queries and Wikidata's actual data structures. Me, so far my own -- no less complicated but rather different -- understanding of all of this comes from working almost exclusively with the JSON representation in the dumps, which give a very different perspective...
)And in the meantime I think I have to go back to Dadra and Nagar Haveli (Q46107) and figure out how to give one of the P31 statements a "preferred" rank, because I think this answers the question now archived at Wikidata:Project chat/Archive/2020/02#time-varying P31.) —Scs (talk) 18:16, 7 March 2020 (UTC)
@Scs: Done that ... it's the up & down arrows to the left of the value field. Good luck with SPARQL; don't think it'll take you long, but you must grok the data model. :) --Tagishsimon (talk) 18:33, 7 March 2020 (UTC)

Automatically add and fill qualifier of a property based on content of the item in it?

I asked about this a while ago at Property talk:P5972#Automatically fill language of work or name (P407) but nobody replied and it's been two months, so I'd like to ask again.

The property translation (P5972) is controversial (to understate it), but it's to my knowledge been at least for now agreed upon (see deletion discussion) that it is a mildly acceptable way to link lexemes because we don't have a good consensus on stuff like whether verbs should have items to link them together.

So translation (P5972) is a property I end up using a lot when making Spanish lexemes that already have English equivalents. However, there is one problem that makes it a lot slower to use and add to many lexemes quickly: to make the translations say what language they are in without having to click the links and navigate away, one must manually add a value for language of work or name (P407) each time, slowing down the process of adding this already rather unwieldy property to lexemes.

As each instance of translation (P5972) contains a value that is a lexeme sense, is there some way that this property could be changed to automatically show a value of language of work or name (P407) on it that is equal to the language of the lexeme linked in it? I am not technically knowledgeable enough to understand how this would work or why it could not, but if it did this this property would be a lot faster to use to help to make navigation between lexemes meaning the same thing easy. Thanks! DemonDays64 | Talk to me 23:09, 7 March 2020 (UTC) (please ping on reply)

  • I'd rather try to tweak to the GUI for property values that are senses. Even if no glos is present in the user's language, the lemma should be displayed. Not sure if anything will happen, as I'm not aware of any recent development for lexemes. Maybe the qualifier could be a solution. --- Jura 08:50, 8 March 2020 (UTC)

Bishop Otter College

Bishop Otter College was founded in 1839. In 1977, it merged with Bognor Regis Training College and became the University of Chichester. This history is discussed on the Wikipedia page for the University, and w:Bishop Otter College redirects to w:University of Chichester. I think, though, it would be best to have separate WD items for the institutions. My questions are: 1. Should I link the item for BOC to the WP redirct page in some way? 2. What is the correct way to write the statement "merged with X to become Y?" Levana Taylor (talk) 17:48, 8 March 2020 (UTC)

Yes, Bishop Otter College should have its own item, as a distinct entity, not simply a name change. Unfortunately, it seems there are no "correct ways" of doing anything on Wikidata: it's the wild west with little guidance and lots of chaos so whatever works best, I say do that. Relevant properties for former institutions include merged into (P7888), replaced by (P1366) and followed by (P156). A redirect on Wikipedia can be attached to a Wikidata item by temporarily removing the redirect (e.g. delete the "#REDIRECT") and then linking the page to its corresponding Wikidata item. -Animalparty (talk) 18:06, 8 March 2020 (UTC)

Wikimedian photographer details on Structured Commons

Hello. I'm trying to add creator (P170) to photographs which I uploaded to Commons (as shown here). Then I realised that, in order to do that, we need an item about the particular user. I've looked at WD:N and also stumbled across this discussion from 2018, but cannot decide if creating items for users is allowed. Looking at this list, I've concluded that it is probably allowed. But when attempting to create the item, I get a warning "Per Wikidata notability policy adding links to userpages or userspace is not allowed". What am I missing? If creating a user-item is not allowed, any suggestion on how to add P170? The goal here is to fill structured data on Commons. Appreciate any clarity on this. Rehman 10:56, 8 March 2020 (UTC)

(Copied from the Wikimedia Commons village pump as it would be more relevant here.) I have seen several Wikimedia Commons photographers add a creator link, for example this Wikidata page of Benoît Prieur which they use for authorship information on Wikimedia Commons. I see no reason to exclude Wikimedians who wish to include themselves like this on Wikidata, as this would actually make it easier for them to include authorship information and attribution information on Wikimedia Commons, this would make it within Wikidata's scope as it fulfills a structural need for another project. -- Donald Trung/徵國單  (討論 🀄) (方孔錢 💴) 18:47, 9 March 2020 (UTC)

Wikidata weekly summary #406

82,250,088 Wikidata pages

Somewhere last year I noticed on this page that there were about 60,000,000 (sixty-million) Wikidata pages but this has grown with around 20,000,000 (twenty-million) pages in a relatively short amount of time, is there a specific reason for this explosive growth? And where can I find more detailed statistics about the content created and how many items belong to what type of data? I honestly find it curious how quickly Wikidata grows in the millions surpassing even Wikimedia Commons in number of pages in such a short amount of time.

How many of these pages are bot-created Vs. Human-created? It's quite interesting and exciting seeing Wikidata grow so quickly in such a short time span. -- Donald Trung/徵國單  (討論 🀄) (方孔錢 💴) 20:26, 9 March 2020 (UTC)

  • This Grafana dashboard is a good entry point for detailed statistics around Wikidata; there are also valuable links to external tools provided.
  • Most activity here is automated in some way, and this also applies to item creations. I'd be surprised if more than 5% of item creations were done manually.
  • Particularly astronomical object (Q6999) items have been amassed since early November (from 400k to 5.8M). Not sure whether scientific article items are created in large numbers currently as well.

Creating a property for Zodiac sign

Such a property could be useful when you know someone's zodiac sign but not their exact date of birth. What do you others think?--Trade (talk) 22:00, 8 March 2020 (UTC)

Really bad idea. Can be derived from whatever date range you enter for the DoB. --Tagishsimon (talk) 23:02, 8 March 2020 (UTC)
It would make it infinitely easier to query people with specific zodiac signs. After all, many people are interested in astrology. --Trade (talk) 23:44, 8 March 2020 (UTC)
Yes. Ascribing completely bollocks information to items normally makes it easier to query for the completely bollocks data. Compelling argument. --Tagishsimon (talk) 02:02, 9 March 2020 (UTC)
We should be using reliable sources. I wonder if Trade can give an example of any person where there is a reliable source for the person's zodiac sign, but not for the person's date of birth. Jc3s5h (talk) 23:25, 8 March 2020 (UTC)
It's not exactly an rare thing when it comes to fictional characters. The Sims video game series is a good example of that. --Trade (talk) 23:44, 8 March 2020 (UTC)
  • I tend to agree with this, although it does raise an interesting point, if we wanted this derivation to be represented in the data then the zodiac sign items themselves need to be associated with the date ranges somehow? It looks like currently they're not, see Libra (Q134394) for example. --SilentSpike (talk) 23:29, 8 March 2020 (UTC)
I think at the moment we don't have any capacity to include "single days" as dates - things like day in year for periodic occurrence (P837) have to use items, so Valentine's Day (Q37587) - day in year for periodic occurrence (P837) - February 14 (Q2332). So there isn't really a data model (or data type) suitable for representing this (though we could probably hack something together with qualifiers). Having said that, I'm on the side of "we probably don't want to have a property for this" - we can calculate it for the vast majority of people if we ever have a reason to, and there's only a small fraction where we can't calculate it, would want to know, and can find a reliable source saying what it is. Andrew Gray (talk) 21:59, 9 March 2020 (UTC)
In addition to the points made by Andrew Gray, there is no exact correspondence between zodiac signs and dates. It varies from year to year, and also depends on the time zone. The transitions do not occur at midnight, so there will always be days that are one sign in the earlier part of the day and the next sign later in the day. Jc3s5h (talk) 23:19, 9 March 2020 (UTC)
Didn't there used to be a page for property proposals where the suitable data model have yet to be created? --Trade (talk) 23:41, 9 March 2020 (UTC)

Request for feedback: Research on use of lists and queries for Wikidata maintenance work

Hello all,

A few weeks ago, the Wikidata UX team talked to nine people about how they improve and enrich data on Wikidata using queries and lists. The research shows that work practices, tools used and goals are very diverse. We noticed that communication and code examples are key in learning SPARQL and that people often worked on closing gaps in data and on finding problems in data structure and modeling.

Before moving on with the research, we would like to have your feedback on the existing results, to check if they adequately represent the goals, activities and problems when using queries and lists. All comments are very welcome, even if we won’t necessarily be able to cover all the possible variations of workflows in the final research.

To give feedback on the slides, feel free to comment directly in the document or to leave your comment below, indicating the slide number and/or quoting the text.

On top of that, if you are an experienced user of Petscan (for list building as well as statement creation based on Wikipedia Categories) we would love to hear more about how you use the tool. PetScan use was mentioned several times in the interviews but we could not cover the process in detail.

Thanks in advance for your help, Jan Dittrich (WMDE) (talk) 09:24, 10 March 2020 (UTC)

  • It could be interesting to see a short table with four columns:
  1. what problem the user is trying to fix
  2. what tool they are using
  3. which query they use to find items
  4. where that query is stored
PetScan used to be a great tool for many, until it broke sometimes last year. Technically, I think it didn't "break", but WMF cut its resource allocation, so it stopped working.
Did anyone mention the constraint reports? --- Jura 12:09, 10 March 2020 (UTC)
Also, I think it's better to collect feedback onwiki than at Facebook or elsewhere. --- Jura 12:17, 10 March 2020 (UTC)

United Nations Security Council sanctions permanent identifier

The United Nations Security Council assigns a Permanent Reference Number to every individual and entity listed for one of their sanctions list. This is often useful for Wikipedia articles such as en:List of designated terrorist groups ([3]). These identifiers follow a fixed format where first two letters refer to a sanctions committee (e.g. QD for Al-Qaeda and Daesh), next letter is for indivuduals or entities (i or e) and then a unique number within the corresponding list. Each entry has a corresponding page at with a Narrative Summary ([4]) but, as far as I know, there are no direct URLs to get them from Permanent Reference Numbers. Do you think it would be reasonable to add a new identifier property? --MarioGom (talk) 09:04, 9 March 2020 (UTC)

Yes I think it would, identifiers do not need to have a formatter URL, it's just very common that they do and makes life a bit easier when they do. --SilentSpike (talk) 10:49, 9 March 2020 (UTC)
I would suggest that you contact them to ask whether they have or plan to have links to the narrative summaries based on the permanent reference numbers. I don't even see a way to get to the narrative summary from the consolidated list, and searching for the PRN does not work well. Bovlb (talk) 15:48, 10 March 2020 (UTC)

Creating data-tables to show in Wikipedia - eg. for Corona virus

Hi, I am completely new to WikiData, so I just want to understand what is possible and maybe get some links. Now during the Coronavirus outbreak there are many tables summarizing number of confirmed cases and deaths. These tables are both globally, per country and even per region. Wikipedia is a poor tool for this, as each cell needs to be maintained individually and there are no links or calculations. For example it would make sense to be able to sum the bottom row automatically, it would make sense to have calculated columns (eg. death ratio) and it would make sense to link one country total on the global page to the sum of regions on the country page. All in all, this is data. Can this be organized in WikiData and then linked into Wikipedia tables? Thanks! Osram (talk) 13:35, 10 March 2020 (UTC)

Help with splitting a conflated person item

Unless he completed his PhD at age 13, Christopher Turner (Q5113349) seems to conflate an author (DOB unknown, but likely before 1980) and a footballer (DOB 1987). I read over the help pages and I'm still not sure how to best resolve this - do I create only one new item or two? Alex Cohn (talk) 16:29, 10 March 2020 (UTC)

@Jura1: I just did - thanks! I think I did it right, but would you be willing to look it over for me? The two new items are Christopher Turner (Q87450707) (writer) and Q87450744 (footballer).

Twitter username (P2002)

Why date statement is required? What is this date? Access date? Eurohunter (talk) 19:38, 10 March 2020 (UTC)

Twitter username (P2002) is not a stable identifier, thus the data should be dated so we know when it was true. The constraint is a suggestion constraint, not a requirement. The reason point in time (P585) was chosen (over start time (P580) and end time (P582) which also date the data) is because of the complications around use of the qualifier number of subscribers (P3744) which can change rapidly in time unlike other qualifiers/the main value (which change at specific points in time). Now that I've been running a bot on this data for a bit, I tend to agree with Jura1 (talkcontribslogs) that adding the followers as a qualifier is not a good solution because that data itself really needs to be qualified with P585 separate from the username statement. --SilentSpike (talk) 19:49, 10 March 2020 (UTC)

label service caching issue?

I fixed the label on byte (Q8799); it had been "bytesss". But its conversion to standard unit (P2442) value (which points back at itself) is still showing as "1 bytesss".

2 items, 1 wikisource page

s:Author:William Pinkerton contains one story and one magazine article, and there's a note on it, saying that nothing is known about this author and "It is not completely certain that the two pieces on this page are by the same person." Therefore, out of an abundance of caution, I created two items, one for the unknown author of each piece of writing. I've asked on the wikisource community portal whether they should be combined on a single author page, and consensus is that yes they should. That leaves me with a dilemma: what item do I link the author page to? Levana Taylor (talk) 14:50, 11 March 2020 (UTC)

How about doing three? --- Jura 15:03, 11 March 2020 (UTC)
That's a thought: "William Pinkerton, magazine contributor" linked to WS and cross-referenced to the two single-contribution items using "said to be the same as" (Curran Index is a reference, tentatively suggesting they are by the same person.)

What label should be entered when there are multiple correct spellings?

I'm asking because of Azadeh. In Farsi this is آزاده. In English it is often written as Azadeh, but Azade Shahmiri (whose first name is also آزاده) is absolutely Azade without h, see here: "First of all my first name is misspelled! Azade without 'h' at the end is correct. This is how my name is written on my ID, email and all the other official references. (I know it's more common for Farsi-speakers to put an h but it is what it is!)"

Should I change the English label for Q4832075 to "Azade(h)"? Alexis Jazz please ping me if you reply 17:22, 11 March 2020 (UTC)

  • Azadeh is for people with that spelling in Latin script, e.g. US born persons. Ideally, you'd create an item for the name in Farsi and add there all possible transliterations. If you want you could also make one for "Azade" in Latin script and add that as well. --- Jura 17:27, 11 March 2020 (UTC)

@Adithyak1997: No worries, it's not such a big deal in this instance, but generally in Wikidata you should never remove/replace a statement if it was valid at any given point in time. Instead using start/end time qualifiers and set preferred rank on the preferred value (can use a qualifier to indicate why it's preferred). I've gone ahead and done so with the formatter URL here, though note I've not added an end time to the old format since it's still valid. --SilentSpike (talk) 14:47, 16 March 2020 (UTC)

Policy for ID/schema change?

After some discussion, there is an issue that I remember cropped up before.

  • We have a property P with external IDs.
  • The IDs are used on site X, the primary source for these IDs.
  • Site X changes their ID schema, using new IDs.
  • Site X invalidates the old IDs, they can't be queried/linked to/seen any more.

Do we

  1. Change the property P to use the new IDs, removing the old IDs
  2. Change the property P to use the new IDs, keeping the old IDs as deprecated (note: QuickStatements can not currently mass-change statements to deprecated)
  3. Create a new property for the same site X for the new IDs, keeping the old property P with the old IDs, maybe label/describe as "deprecated"
    • If so, can we fast-track the property creation, arguing that since property P is relevant, so is the new property

I think we need an "official" policy/decision on this at some point. --Magnus Manske (talk) 14:03, 11 March 2020 (UTC)

Is there like a policy section somewhere that this can be added? Iwan.Aucamp (talk) 14:53, 11 March 2020 (UTC)
I think we would really need a broader discussion before declaring this to be accepted policy - eg in the 2017 discussion at Wikidata:Project_chat/Archive/2017/12#Oxford_Biography_Index_Number_(P1415), the general agreement was exactly the opposite, and I'm sure this has been done in a few other cases as well. Andrew Gray (talk) 21:10, 11 March 2020 (UTC)
In general I would prefer #1 or #2 for the situations where the old IDs are of little or no practical use (ie they don't resolve to anything). Otherwise it's a bit confusing to end users if we have two different properties for the same ID, with different values. Andrew Gray (talk) 21:10, 11 March 2020 (UTC)
Question is what's the "practical use" here. I argue that the primary goal of identifiers is identification, and the identifiers (in Wikidata actually "formatter URL"+"identifier fragment") are just names for the things described, in the form of URLs. Following basic linked data principles, these names do not require that they resolve to anything—although in most cases they do, fortunately.
When connecting Wikidata with other linked data services, matching items by identifiers is a pretty common process. It is useful to keep older names (identifiers) for things available in Wikidata, as this might be the only way matches can be found if the other linked data service has not been migrated to the new schema yet.
From the practical point, I think we are limited by our approach how we technically implement the identifiers as "formatter URL"+"identifier fragment". If one of these components changes, one can take a practical approach and add the new value, either the formatter URL in the property page, or the identifier fragment on item pages, with preferred rank, keep the old one with normal rank. Old and new names (identifiers) would still be available, but the new ones that actually resolve to external resources would be much more visible to data users. However, once both formatter URL and the identifier fragment format change, I think we should really create a new property and keep the old one (both property and all statements). —MisterSynergy (talk) 22:40, 11 March 2020 (UTC)
Somehow I doubt two different formats for values can work well in the same property. Property constraints can't differentiate between rank when checking for a given format. Maybe at Commons it can do that? --- Jura 09:11, 12 March 2020 (UTC)
Continued use of the same property when either the URL formatter or the identifier fragment format change is a pragmatic approach; I would not oppose if it was done more rigorously, i.e. with a new property as soon as there is any substantial change in the identifiers. However, I suppose that there will not be a consensus for such a rigorous approach. —MisterSynergy (talk) 09:29, 12 March 2020 (UTC)
I don't really see a consensus for repurposing the existing entity nor for repurposing Wikidata from a database into a webdirectory. How would MARC standards handle this? --- Jura 09:54, 12 March 2020 (UTC)

Copyrights when author "claims no rights"

"I claim no rights to this material, and anyone may use it in any manner they see fit." Is it enough for this list to become CC0? Uzielbot (talk) 23:26, 11 March 2020 (UTC)

Technically no, it's not CC0, which is a specific public domain grant and license. But it's likely to be public domain in the US anyway, combined with the author disclaiming rights, it seems reasonable to call it public domain. Ghouston (talk) 23:39, 11 March 2020 (UTC)

Is it misleading adding coordinates to the items about the COVID-19 outbreak?

Hello. I have started a discussion with @Neo-Jay: at 2020 coronavirus pandemic in Basque Country (Q87452683) about adding coordinates to items related to national/regional outbreaks of the COVID-19 disease. I understand the idea of adding coordinates: we can map things. But as the coordinate is placed in the geographical center of the country where the item belongs we have a point in a place that is not related to the actual outbreak point, and can be really misleading. I would understand adding a point for the COVID outbreak at Wuhan, but not at the geographical center of China, as this is not the main point I want to visualize in any external app (a map, a Wikipedia article...). I noticed this in the article eu:COVID-19_gaixotasunaren_2019-2020ko_pandemia_Euskal_Herrian, where we load the coordinates of events in the template automatically (for example, for an earthquake). As the discussion is not about 2020 coronavirus pandemic in Basque Country (Q87452683) (where the point is in a mountain) but more general, I would like to know your opinion on this. I ping Tobias1984

If the outbreak occurred throughout the said country/region, it's the proper to use the geographic center of that country/region as the coordinate location. If the outbreak occurred only in part of the said country/region, the coordinate location may be changed to a more relevant place. If Theklan is discussing how to determine a best point as the coordinate location (Property:P625) for a COVID-19 outbreak item, that's fine. But it seems that Theklan opposes adding any coordinate location to a COVID-19 outbreak item. If so, I disagree. Coordinate location can be improved, but should not be removed. --Neo-Jay (talk) 11:17, 12 March 2020 (UTC)
Yes, I'm suggesting that the coordinate should give information about where something is happening, and the geographical center of a country is not accurate. -Theklan (talk) 11:45, 12 March 2020 (UTC)
It's a case-by-case issue. The geographic center can also be accurate under some circumstances. If you think that the geographic center is not appropriate for the outbreak in Basque Country (Q87452683), you may change it to a proper point, not simply remove it. As for the specific issue about Wuhan, I think that Wuhan is of course the coordinate location for the outbreak in Wuhan (Q85872051), but may not be the coordinate location for the outbreak in Hubei (Q87402404) and in mainland China (Q83872271). As the coronavirus outbreak occurred throughout every city in Hubei and every province in mainland China, it's proper, in my view, to use the geographic centers of Hubei and mainlan China as their respective coordinate locations (this is not about an earthquake epicenter). Using different coordinate locations for these three items can also make it easy to find the three items on the map in Wikidata query. --Neo-Jay (talk) 11:59, 12 March 2020 (UTC)
What I think is that using the geographic center of an entity for an event is not accurate. We don't use the coordinates of the city a person was born in the Wikidata item of the person, because we can get them easily using a query. If we want to build a map of countries where the outbreak is happening, we can query it easily having countries and then the coordinates of that country. But the event didn't happen in that precise point. -Theklan (talk) 12:41, 12 March 2020 (UTC)
Can coordinate location (P625) be used for an event item? Of course it can. Are you arguing that P625 should not be used for an event? I have put it very clearly, if you think that the geographic center is not appropriate for a specific item, you can change it, but please don't remove it. OK? Can you answer me: what do you think is the appropriate coordinate location for the outbreak in Basque Country (Q87452683)? Please feel free to add it. Please. And you cannot categorically claim that the geographic center should not be used for an event. Again, this is a case-by-case issue (why cannot the geographical center be used as the coordinate location for the outbreak in a small city, e.g., Macau or San Marino?). And we cannot find the the COVID-19 outbreak locations simply by country, because there are many non-country items. For example, the country (P17) of the outbreak in Hubei (Q87402404) is China, but we need to find Hubei as the location on map. And we also cannot find the outbreak in Europe on map by country (P17), because it has many values. --Neo-Jay (talk) 13:19, 12 March 2020 (UTC)
Yes, coordinate location (P625) can be used for an event if the event happens in a determined place: an earthquake (2018 Papua New Guinea earthquake (Q50178713)) but not a hurricane (Hurricane Barry (Q65506262)), a battle (Normandy landings (Q16470)) but not a war (World War II (Q362))... adding a coordinate for the center of Asia (en:Geographical_midpoint_of_Asia) to an item about the COVID-19 in Asia (2019–20 coronavirus pandemic in Asia (Q86521237) by the way, the point here is not the center of Asia) doesn't make any sense. If you want to show the center point of the places where COVID-19 happened or the birth places of famous people who died by the disease you can build a query for that without adding misleading information to the item. -Theklan (talk) 13:46, 12 March 2020 (UTC)
Do you mean that at least adding a coordinate for the geographic center to an item about COVID-19 outbreak in a relatively small area (e.g., as small as that in Normandy landings (Q16470), such as outbreaks in Macau (Q85872060) and in San Marino (Q87123561)) might make some sense? So the geographic center can be used as the coordinate location for at least some COVID-19 outbreaks? Is that correct? Frankly speaking, I don't know how to build a query to show the center point of the places where COVID-19 happened if not using coordinates (P625). For an item about the "outbreak in place X" (place X can be a continent, region, country, province, city, etc.), although the item's label is very clear to a human, how to let machine understand what place X is? It cannot be determined by "location" (P276), which may include place X's subdivisions. For example, how to build a query to get California for Q87455852 (COVID-19 outbreak in California)? Although P276 (location) of Q87455852 is California now, it may also have other values (e.g., counties in California). If coordinate location (P625) should not be used, can we use coordinates of northernmost/southernmost/easternmost/westernmost points (P1332/P1333/P1334/P1335) for outbreak items? It seems inappropriate to me. If you could teach me how to build a query to show the outbreak place that the item is about without adding coordinates, I would sincerely appreciate your help. --Neo-Jay (talk) 17:22, 12 March 2020 (UTC)
You can do with the easiest possible way:
SELECT ?SARS_CoV_2 ?SARS_CoV_2Label ?country ?countryLabel ?coord WHERE {
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  ?SARS_CoV_2 wdt:P1478 wd:Q82069695.
  ?SARS_CoV_2 wdt:P17 ?country.
  ?country wdt:P625 ?coord
Try it!
You look for the country (P17) where something has immediate cause (P1478) SARS-CoV-2 (Q82069695) is happening and then you ask the coordinate location (P625) of that country (P17). So you don't have to add coordinates to the event and mislead people who is reading about that item's location.
You can also make it show the case of California and others:
SELECT ?SARS_CoV_2 ?SARS_CoV_2Label ?country ?countryLabel ?coord WHERE {
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
  ?SARS_CoV_2 wdt:P361 wd:Q83873577;
    wdt:P276 ?country.
  ?country wdt:P625 ?coord.
Try it!
Here, we ask something that part of (P361) 2020 coronavirus pandemic in the United States (Q83873577), and we ask for the coordinates of the location (P276), that can even be more than one. -Theklan (talk) 22:43, 12 March 2020 (UTC)
You use P17 (country) or P276 (location ) to locate an item. But as I put it, P17/P276 of item "outbreak in place X" may have many values other than place X. For example, your first query generates more than 100 locations for item Q81068910 (global outbreak of COVID-19), whose P17 (country) has many values. And P276 of Q87455852 (COVID-19 outbreak in California) may also have many values other than California (e.g., counties in California) and can generate many locations for this single item on map. I need to locate only one entity for an item, e.g., only Asia for Q86521237 (outbreak in Asia), and only California for Q87455852 (outbreak in California), not multiple countries for Q86521237 or multiple counties for Q87455852. Furthermore, your queries may make different items share a same point on map. For example, both Q87455852 (outbreak in California) and Q83873577 (outbreak in the US) have statement "country (P17): United States". What I need is to locate each item at a single and unique location on map so that we can layer the map by the item's other data, e.g., P1603 (number of cases) and P1120 (number of deaths). Unfortunately the two queries above cannot achieve it.--Neo-Jay (talk) 23:29, 12 March 2020 (UTC)
If you have data sufficient to enable you to add a P625, then you have data sufficient to choose a value or values for P276 of granularity appropriate to the locus of the outbreak - a county, or counties, in the US, rather than a state. --Tagishsimon (talk) 23:40, 12 March 2020 (UTC)
You are right. P625 (coordinate location) may also have more than one value. Although P625 has a single value constraint, its different values can be separated by separators. My query, which uses P625 to locate each item at a single and unique location on map (for now) and can layer the map by level of cases/deaths/CFR, is as follows:
SELECT ?outbreak ?outbreakLabel ?map ?coord ?cases ?case_level ?deaths ?death_level ?CFR ?CFR_level ?start_time ?end_time
  ?outbreak p:P31 ?x.
  ?x ps:P31 ?y;
     pq:P642 wd:Q84263196.
  ?y wdt:P279* wd:Q3241045

  OPTIONAL {?outbreak wdt:P1603 ?cases}

Now such a mission seems impossible if we cannot locate item "outbreak in place X" solely at "place X" (not place X's country or subdivisions). Can we add "P518 (applies to part): place X" as a qualifier for item outbreak in place X's statement "instance of: disease outbreak (or its subclass, e.g., pandemic)"? I don't know whether it is appropriate and whether qualifier P518 can also have more than one value in this case. --Neo-Jay (talk) 00:14, 13 March 2020 (UTC)

Cleanup of Wikidata:Property_proposal/Authority_control

There are some property proposals that are not being transcluded in Wikidata:Property_proposal/Authority_control - it seems it is related to the amount of transcludes. There are many properties marked ready there and some that are already handled. Should I move the completed ones to archive by hand and can someone create the properties marked ready? Iwan.Aucamp (talk) 07:30, 11 March 2020 (UTC)

Maybe I can move the properties that are created/done to the bottom of the page and move ones who are ready above them and under discussion to top? Iwan.Aucamp (talk) 08:15, 11 March 2020 (UTC)

I requested permission to create properties so I can help out. Can someone clarify though if it is okay if someone other than the person who proposed a property marks it as ready? For example, would it be okay if I marked Wikidata:Property_proposal/ELAR_ID as ready? Iwan.Aucamp (talk) 22:39, 12 March 2020 (UTC)

I think properties should always be marked as “ready” by someone other than the proposer. - PKM (talk) 03:48, 13 March 2020 (UTC)

Is there consensus that this is the case? I may be an outlier. (Not the first time...) - PKM (talk) 21:05, 13 March 2020 (UTC)
Proposals should be marked as "ready" (which simply flags them for attention of a property creator or admin) by anyone, once there is either a clear consensus emerging, or discussion has died down. There is no sound reason to exclude the proponent from this. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 00:33, 14 March 2020 (UTC)

Should I keep taxonomic synonyms as item?

Yes my understanding is that taxonomic synonyms are being kept separate and we associate sources using different names with different items. --Jarekt (talk) 00:13, 13 March 2020 (UTC)

dispatch lag super high today

Since about 0415 UTC (a little after midnight US EDT) this morning, the dispatch lag from wikidata to client wiki's has been averaging about 5 minutes continuously. This has basically blocked all bot edits on Wikidata (all the ones that pay attention to maxlag). This is not the usual WDQS lag problem - for once the lag on the query servers has been fine (less than a minute except for a brief period about 2 hours ago) - probably because there have been almost no bot edits. We haven't had this sort of lag to client wikis for over a year - does anybody have any idea what could be causing it? It will become very hard to keep Wikidata up to date if bots are blocked like this for long. ArthurPSmith (talk) 14:29, 13 March 2020 (UTC)

According to this dashboard, dispatch lag fell sharply around 14:53.

Is "former hospital" and intersection of "hospital building" and a "former building or structure"?

It seems a former hospital (Q64578911) is the intersection of the subclass_of=hospital_building and a subclass_of=former_building_or_structure, am I wrong? --RAN (talk) 19:47, 11 March 2020 (UTC)

This seems wrong - a building that was once a hospital but is now a block of flats is a "former hospital", but it does not follow that it is a "former building or structure". It can change its purpose but still be in existence. Andrew Gray (talk) 21:15, 11 March 2020 (UTC)
I'd make it an instance of building (Q41176) and give it multiple use (P366) statements with dates. "Former X" items should be avoided in any case. Ghouston (talk) 21:32, 11 March 2020 (UTC)
Yes, we will have to figure out how to distinguish repurposed. --RAN (talk) 23:55, 11 March 2020 (UTC)
This is a terrible mess in Commons. Ghouston (talk) 23:57, 11 March 2020 (UTC)
I'm pretty sur that a building built as an hospital should have hospital building (Q39364723), instead of building (Q41176). A hospital is a distinct built that a church, a house or a prison. Like if you look Q27907328 It look like a church, even if it's now a public library. If the building id now a aparment building, then you should use use (P366) to mark the change of use. If the hospital if demolised, I generally use state of conservation (P5816) --> demolished or destroyed (Q56556915) instead of former hospital (Q64578911). --Fralambert (talk) 00:26, 12 March 2020 (UTC)
Perhaps in some cases, but probably not all. There's not much (if any) external difference between modern apartment, office and hotel buildings, and they can be converted between such uses. A building also has an architectural style, which can be represented with architectural style (P149) instead of a class hierarchy. I know for example of a 19th century building, which was constructed as a bank, but the bank never occupied it and it was used as a chemist shop, then a bank about 10 years later, and is currently a cafe. It may have some stylistic characteristics that would indicate its original use, but perhaps it's confusing to be calling it a bank building now? There may also be buildings that were never used for their intended purpose. Ghouston (talk) 01:13, 12 March 2020 (UTC)
Bank building have generally a safe (Q471898), wich is probably present in the building. If we desire a more general purpose, we can also use office building (Q1021645) or commercial building (Q655686). All the usage of your exemple enter in the second one. But I agreed that older institutional buildings, like school, hospital or convent often look the same and are often interchangeable. If it could help, in my line of work, we divide buildings in 5 great famillies: Residential, agricultural, commercial, industrial and institutional building. At the difference of the other national museums of Ottawa Canada Science and Technology Museum (Q1163464) is a located in a former bakery. It's probably of good idea to put industrial building (Q12144897) in the item of the building even the curent use is a museum. --Fralambert (talk) 02:00, 12 March 2020 (UTC)
Possibly, although it's hardly unknown that barns or industrial buildings or schools are converted into residences, and it may still seem odd to describe a block of apartments as an industrial building. Museums can be housed in any random left-over structure, as well as new build, so having a museum "building type" wouldn't work well. Ghouston (talk) 02:02, 15 March 2020 (UTC)


PAWS is a great tool, except for WikiData. When you develop a script, it waits 11 minutes due to database lag to only read an item. Then you get an error because you made a small error in your script. This makes the tool useless. Edoderoo (talk) 15:51, 12 March 2020 (UTC)

You can overwrite the standard pywikibot configuration in PAWS by creating a file "" (file ending .py, not .ipynb!) in the main folder of your PAWS account. Maxlag can be deactivated by adding "maxlag=0"—this is okay for testing when developing a script, just do not run any production batches with this configuration. It might also be worth to add "put_throttle=1" permanently to that config file, as this increases your edit rate up to 1/sec. —MisterSynergy (talk) 16:07, 12 March 2020 (UTC)
The put throttle is acceptable for me (I have an Ubuntu box running pywikibot for production), but it is a good tip. I'll try out the max-lag parameter, as without this it becomes too annoying. Edoderoo (talk) 17:05, 12 March 2020 (UTC)
The other thing you might want to do is temporarily turn off your bot! :-)
(I mention this only because it shows up on someone's list just below of heavily-active bots correlated with major dispatch lag.) —Scs (talk) 12:12, 14 March 2020 (UTC)
Worth noting that when bots overwhelm the capacity of the RDF export by ignoring maxlag, wikidata - which is to say you and your fellow wikidata users - appear to suffer a disproportionate penalty seen, most days, in the Edit & Creation rate chart - a gap-toothed pattern the area beneath which is much smaller than that beneath the more rare within-capacity periods. --Tagishsimon (talk) 12:26, 14 March 2020 (UTC)

Labels for standards with alphanumeric identifiers, exact match (P2888) vs official website (P856)

So there are currently some items with alphanumeric identifiers in their English names:

  • X.509 (Q1065865) "X.509 : Information technology - Open Systems Interconnection - The Directory: Public-key and attribute certificate frameworks"
  • G.711 (Q952898) "G.711 : Pulse code modulation (PCM) of voice frequencies"
  • ISO/IEC 14882 (Q66084444) "ISO/IEC 14882 - Programming languages — C++"

I don't exactly like that, I think the full names (as quoted) should be used not just the identifier. Are there any guidelines here?

Then I added the following exact match (P2888) statements:

I'm not sure if this is right use of exact match (P2888) - I guess the same can be added as official website (P856), but the problem there is that you have to provide a language - which I don't really want to for these. What is the right approach here? Iwan.Aucamp (talk) 12:32, 14 March 2020 (UTC)

Tubezlob Tris T7 TT me

Pictogram voting comment.svg Notified participants of WikiProject Labels_and_descriptions

For your first point, we have Help:Label which is unambiguous "The label is the most common name that the item would be known by." So that would be X.509, not a mouthful of official title. Also known as is for all the other names you can come up with. --Tagishsimon (talk) 12:37, 14 March 2020 (UTC)
@Tagishsimon: From Help:Label "Because the aim is to use the name that an item would be known by to the most readers, labels should reflect common usage. When it comes to scientific names, for example, of a species, labels should use a species' common name, however items must always also have the scientific name listed as Alias."
To me this would rather suggest quite the opposite of what you suggest - or at least would favour "C++ standard" for ISO/IEC 14882 (Q66084444) , "Pulse code modulation (PCM) of voice frequencies" for Template:Q952898 and "Public-key and attribute certificate frameworks" for Template:Q1065865.
Either way, specific guidance in Help:Label that speaks to this would be helpful because there is no consistency as it stands on this matter. Iwan.Aucamp (talk) 12:52, 14 March 2020 (UTC)
My own feeling about Wikidata labels is that if you are arguing about them, you are probably doing something wrong.
Arguments about the "right" names for things are for the Wikipedias, not Wikidata.
Labels here are for convenience, for people who don't remember that Q100 is Boston.
As long as the label is easily recognizable, it's fine, and no one needs to worry about whether some other label might be "better". (In my opinion.) —Scs (talk) 13:28, 14 March 2020 (UTC)
@Scs: There is already guidance on labels here which is quite specific on some matters and at least to one person very clear on this specific matter. The lack of norms will lead to edit wars and needless argument - it won't avoid argument. For example if someone goes and changes the label RFC 1323: TCP Extensions for High Performance (Q47263971) from "RFC 1323: TCP Extensions for High Performance" to "RFC 1323" and the bot changes it back. Why not just avoid this by putting some guidance down on the matter? Easily recognizable is a subjective attribute - to me "EN 301 347" and "ISO/IEC 14882" for example is not easily recognizable - but this is the preferred label in Tagishsimon's view.
I had look and I would say the majority of standards in wikidata do not just use the identifier at the moment. Iwan.Aucamp (talk) 13:52, 14 March 2020 (UTC)
Empirically - or, at least, anecdotally based on my experience - lack of norms does not, in fact, lead to edit wars and needless argument. My advice is that in most cases, there is a common name. It may well be C++ standard rather than ISO/IEC 14882, but it'll equally be Z39.50 rather than Information Retrieval (Z39.50), or Information Retrieval (Z39.50):Application Service Definition and Protocol Specification. And where there's not an obvious common name, then either a) be happy with a label and an Also Known As or several; or else b) curate a set of items such that the labels and aliases follow a consistent pattern. We cannot give much more useful guidance for a broad set of items, beyond the common name pattern, since for some items the spec ID, for some the formal title, for some, some other formulation, will be the common name. For a much narrower sets of items, it may be possible to provide more detailed guidance, and if so, typically, a project will discuss and recommend; or an individual will curate. As Scs notes, the specifics of labels, descriptions and aliases are of less importance in Wikidata; they exist mainly to enable the item to be discovered through search. Where it is important to record a definitive "label", title (P1476), and/or a specific ID, such as RfC ID (P892), is preferred. Having good labels, descriptions and aliases is important for discovery; but spending too much time worrying about which of several candidates gets the "label" slot and which gets the aka is probably not time well spent. --Tagishsimon (talk) 16:05, 14 March 2020 (UTC)
There's a special place -- I think it's w:Talk:Derry -- reserved for anyone so idiotic as to edit war on Wikidata labels. —Scs (talk) 17:23, 14 March 2020 (UTC)

Notice of proposed changes

Please take note of the following proposed changes:

Iwan.Aucamp (talk) 20:26, 14 March 2020 (UTC)

You're right on the first on; it's a subclass, not an instance. Arguably wrong on the second. From "An Internet Standard is documented by[1] a Request for Comments (RFC) or a set of RFCs", and, "Engineering contributions to the IETF start as an Internet Draft, may be promoted to a Request for Comments, and may eventually become an Internet Standard." RFCs can, I think, legitimately be seen as that set of IAs that are still at the RFC stage. This may not be your preferred ontology; but that is beside the point. Wikidata is capable of rich descriptions and, explicitly, in Help:Statements#Multiple values: "If an item by nature can have properties with multiple values (like children of a person or official languages of a country), it is perfectly acceptable to add them." --Tagishsimon (talk) 21:24, 14 March 2020 (UTC)
@Tagishsimon: An Internet Standard (Q290378) (note capitalized, therefore proper noun as per Help:Label) is a very specific thing - the official list of Internet Standards can be seen here as per

The "Internet Official Protocol Standards" document, now as RFC 5000 [RFC5000], has always been listed in the Internet Standard series as STD 1. However, the document has not been kept up to date in recent years, and it has fallen out of use in favor of the online list produced by the RFC Editor [STDS-TRK].

Retirement of the "Internet Official Protocol Standards" Summary Document, Internet Engineering Task Force, , doi: 10.17487/RFC7100
Further, there is RFC 1796: Not All RFCs are Standards (Q47470496) - which in an of itself is a good example of an RFC which does not intend to represent an Internet Standard (Q290378)

This memo provides information for the Internet community. This memo does not specify an Internet standard of any kind. Distribution of this memo is unlimited.

Jon Postel and Steve Crocker, Not All RFCs are Standards, Internet Engineering Task Force, , doi: 10.17487/RFC1796
It goes on to explain:

In fact, each RFC has a status, relative to its relation with the Internet standardization process: Informational, Experimental, or Standards Track (Proposed Standard, Draft Standard, Internet Standard), or Historic. This status is reproduced on the first page of the RFC itself, and is also documented in the periodic "Internet Official Protocols Standards" RFC (STD 1).

Jon Postel and Steve Crocker, Not All RFCs are Standards, Internet Engineering Task Force, , doi: 10.17487/RFC1796
Further, even if every single RFC was on IETF's Standards Track (which not every RFC is), then every RFC would still not be a Internet Standard (Q290378) (propper noun) - it may be a "internet standard" (regular noun) - and I don't object to such a classification (under said circumstances, which are not the case) - but that is not what is being discussed here. Iwan.Aucamp (talk) 21:53, 14 March 2020 (UTC)
This quote "An Internet Standard is documented by[1] a Request for Comments (RFC) or a set of RFCs" implies the inverse relation to what I want to remove - and I would say supports my proposal. If you want to add Internet Standard (Q290378) subclass of (P279) Request for Comments (Q212971) I would agree - it makes sense. That is the opposite of the relation I want to eliminate. Iwan.Aucamp (talk) 21:58, 14 March 2020 (UTC)
Yes, there have been things like April Fools joke RFCs, the "Internet standards" are a subset. Ghouston (talk) 01:45, 15 March 2020 (UTC)

In so far as magazine is a subclass of periodical, you can make that change without affecting the price of bread. I hope you develop the confidence to make changes that don't need discussion without bringing them here. As to the descriptions. Sigh. They're pithy strings which rarely encompass the whole scope of their item, for the obvious reason of their brevity. By all means tinker with them if it makes you happy, so long as by doing so you do not change their fundamental meaning. Magazines are a subclass of periodical; it's fine to describe a news magazine as a blah blah periodical blah blah. Users will pick up the Magazineiness from the label. --Tagishsimon (talk) 12:00, 15 March 2020 (UTC)
If someone changes the label of professional magazine (Q55630524) and news magazine (Q67016056), as I suggest, then users will in fact not pick up magazine from the label. There are periodicals which are not magazines, and such periodicals could be issued by a governing body of a profession. Iwan.Aucamp (talk) 12:35, 15 March 2020 (UTC)
The actual guidance of labels seems to indicate that there is some conflict between the label and description here. "The label is the most common name that the item would be known by." At least to me, it is seem like the common name of all "periodical published by the governing body of a profession" is not "professional magazines". Iwan.Aucamp (talk) 12:45, 15 March 2020 (UTC)
All "professional magazines" can be described as "periodical published by the governing body of a profession". Not all "periodical published by the governing body of a profession" are "professional magazines"; see, for instance, society journal (Q73364223). Probably better to work from the label to the description, rather than from the description to the label. --Tagishsimon (talk) 13:49, 15 March 2020 (UTC)

@Moebeus, Edward: Maybe you have some inputs? Iwan.Aucamp (talk) 12:40, 15 March 2020 (UTC)

I welcome any effort attempting to create some order in this area. I've mainly been looking at Q2514037 and Property:P2813 and found the space to be rather messy/confusing as it stands. Don't have much input other than to say my personal preference would be to see us move towards the model currently promoted by Project Books, with a single P31 for all magazines and the many, many subclasses and variants moved to Property:P7937 and other relevant properties.

Error in the Library of Congress database

Does anyone have a contact or know the procedure for alerting the Library of Congress of an error in their catalog? I've noticed that their listing linked from George Van Santvoord (Q61782159) includes both that author's works as well as those by George Van Santvoord (Q61782109). The authors have the same name but one was a Yale scholar of English literature and the other specialized in US law. The error has spread into VIAF and WorldCat. --EncycloPetey (talk) 04:49, 15 March 2020 (UTC)

I don't, but it might be a good idea to qualify the statements with something like reason for deprecation (P2241): conflation (Q14946528). Vojtěch Dostál (talk) 16:07, 15 March 2020 (UTC)
@EncycloPetey: I ran into this problem as well a while ago; seems to be the right way to report it. Don't expect a quick resolution though; the one I reported hadn't been fixed as of last time I checked, after a couple months. Vahurzpu (talk) 16:11, 15 March 2020 (UTC)

Killed in the line of duty

killed in the line of duty (Q87013982) I want to use it to tag police and firemen, just as we have killed in action for military people. Should it be added as a second line for "manner of death"? Eventually I want to see how many entries at Wikidata have entries in the officer_down website, to see if it is worth adding as a new data field. Please make additions to this q-entry. --RAN (talk) 00:29, 4 March 2020 (UTC)

@Richard Arthur Norton (1958- ): Is it only for people that were killed by someone or for every death regardless of the cause? English 'killed' is ambiguous, I want to be sure of the correctness of the translation. Wostr (talk) 13:46, 5 March 2020 (UTC)
In English it is not just murdered but died doing their job as a first responder, a fireman killed when the roof collapses, a ambulance driver hit by a car. --RAN (talk) 13:54, 5 March 2020 (UTC)
"Killed in the line of duty" in English has no implication of homicide. - Jmabel (talk) 16:56, 5 March 2020 (UTC)
This is getting off-topic but that's wrong. Homicide is one person causing the death of the other, be it murder, self-defense, or unintentional. If a cop is chasing a suspect and that suspect shoots the cop dead, the suspect has committed homicide and the officer is considered killed in the line of duty. If a cop is getting out of a car and killed by a passing motorist, that is homicide, considered killed in the line of duty. Many English-language sources use this connotation. [6], [7], [8]. -Animalparty (talk) 21:39, 5 March 2020 (UTC)
If an on-duty police officer has a heart attack from running too fast after a suspect, he was "killed in the line of duty" but barring some really arcane legal theory, there was no homicide. Similarly, if a police officer or firefighter dies trying to save someone from a burning building, etc. - Jmabel (talk) 23:00, 5 March 2020 (UTC)
Are killed in the line of duty (Q87013982) and Line of Duty Death (Q1036604) the same concept?--Afaz (talk) 08:59, 6 March 2020 (UTC)

    • I'd say to create out a second, more specialized item for that (I presume English-language) Wikipedia article. - Jmabel (talk) 00:01, 17 March 2020 (UTC)

Do something about Covid-19

Hi! Like many others I am currently exploring how the stuff that I know best could be used to help with a crisis like COVID-19 (Q84263196) and also similar situations in the future. One thing that came up in discussion with others would be to be able to visualize and push emergency notifications or important alerts from nearby relevant organizations, such as hospitals, counties, school districts, etc.

Some ideas:

  1. We already have a property for the official website (P856), but often these Websites have a specific page or web feed (Q842397) or Common Alerting Protocol (Q5153276) for emergency notifications and important updates. So creating a property that links to that could be one thing.
  2. Making sure the data for certain domains - say all hospitals in a country have all required data, such as coordinates, websites, phone number - is complete.
  3. Setting up a Wikiproject to discuss ideas and explore what we could do, where we could easily reach out to each other who are willing to help with such situations?

Thoughts? --Denny (talk) 22:32, 13 March 2020 (UTC)

Option 2: improving health provider, hospital and emergency services structured data, most particularly official website, social media handles, coordinates. This can be expected to improve google infoboxes, amongst other things. Not sure offhand how we relate localities served to provider items, where that's relevant. --Tagishsimon (talk) 23:25, 13 March 2020 (UTC)
Sounds great and super actionable. We should be able to start with hospitals, and make sure they are well covered. If a quick check to the Web is reliable, the US has about 5000 hospitals, so the whole world might have up to an order of magnitude more. That sounds like a doable list. --Denny (talk) 00:05, 14 March 2020 (UTC)
In the past, I had a look at them once a year or so. This is slightly better than what I had seen at Wikipedia (some lists there include places closed for years). If you find a hospital that no longer exists, please add former hospital (Q64578911) to it. Given the lack of other updates, I'd rather see the official website added than a possibly incorrect or outdated phone number.
Key properties we have are number of hospital beds (P6801) and emergency services (P6855). These somehow mitigate that the definition of "hospital" varies now from one country to another. Coverage for Japan is probably quite good.
BTW, not sure how to add "if you have symptoms, don't walk into the next hospital and infect everybody else". Maybe building a list of relevant hotlines might help. In general, South Korea seems to have figured out how to go about it. --- Jura 08:00, 14 March 2020 (UTC)
Maybe even do an import from OSM, limited to hospital data? --SCIdude (talk) 08:09, 14 March 2020 (UTC)

Jura, thank you, that is a great page to start with! --Denny (talk) 19:03, 14 March 2020 (UTC)
Yes, working on the above list of hospitals is a good starting point. Others include relevant Scholia profiles (e.g. for the SARS-CoV-2 virus, for the COVID-19 disease, for the COVID-19 pandemic, for the transmission of the virus or for social distancing), and for disaster preparedness more generally, we also have Wikidata:WikiProject Humanitarian Wikidata. --Daniel Mietchen (talk) 00:15, 16 March 2020 (UTC)
Yay! --Denny (talk) 16:27, 16 March 2020 (UTC)

Automatically fill P131 based on coordinates

Hello. Is there a tool to semi-automatically or automatically populate located in the administrative territorial entity (P131), if coordinate location (P625) is already populated? Rehman 04:04, 15 March 2020 (UTC)

  • Yeah, this would be really cool. It would likely require fetching data from OpenStreetMaps via OSM relation ID (P402). Vojtěch Dostál (talk) 16:10, 15 March 2020 (UTC)
  • Presumably there would be some cases where it would be contested/ambiguous. But generally it's a good idea. BrokenSegue (talk) 17:08, 15 March 2020 (UTC)
OpenStreetMap is licensed in another way as Wikidata. So I think it is not allowed to reconcile the data from OpenStreetMap with Wikidata. --Hogü-456 (talk) 18:03, 15 March 2020 (UTC)
geoshape (P3896) could be useful here --SilentSpike (talk) 20:37, 15 March 2020 (UTC)
  • Surely you also need to know the point in time as the administrative entity could not have existed at the same time as the entity? --SilentSpike (talk) 20:37, 15 March 2020 (UTC)
  • Based on this, I would not recommend coordinate-based automatic filling.--Ymblanter (talk) 21:12, 15 March 2020 (UTC)
    • Agree with Ymblanter. Many many coordinates are wrong. Some are grossly wrong, that may be picked up by Paleim's tools. Some are slightly wrong, due to import from a rather low-precision coarsely-rounded source (sometimes via cebwiki), which then pushes them into the wrong administrative area. Auto-estmimation of P131s has to be heavily chacked, and is no substitute for extraction for authoritative databases or archival sources. Jheald (talk) 22:26, 15 March 2020 (UTC)
@Tagishsimon: would that match your experiences with Scotland? Jheald (talk) 22:27, 15 March 2020 (UTC)
Scotland had very many wrong coordinates, certainly in the hundreds of, for (at the time) ~46k geocoded items. For many items, it was possible to acquire P131 data from a reliable source, meaning that we could visualise coordinate errors - see an example at ... that would get lost if P131 had been ascribed automagically based on coord. Equally, I added many P131s based on coords, for item sets for which I've not yet found an RS. Such P131s have no ref. Some will contain garbage.
I wouldn't recommend indiscriminate addition of P131 based on P625, but think it's a fair thing to do for a dataset you intend to curate; e.g. for Scotland, it's possible to cross-ref P131s with categories for the linked article, as one means of wringing out errors. As for technique, I used WDQS's 'search around point' geospatial search; you can see some evidence of that in such as the big East Lothian circle. --Tagishsimon (talk) 23:12, 15 March 2020 (UTC)
  • Hi Jheald and others. I agree that most coords are inaccurate, and automatically mass adding things like P131 based on coords is a bad idea. I am seeking if there is a way to do it for selected sets of articles - and that too maybe semi-automatically instead of fully automatic (we need to click confirm, etc). To give an example, I've recently went ahead and updated all coords in en:List of mountains of Sri Lanka. I now know all of those coords are accurate. Hence it would be nice if there was a way to fill (at least) P131 based on the coords of that set of articles (I'm sure there would be more properties that could be populated - country, timezone, etc). This is a small set, but suppose we have a bigger set, a tool that could do this would surely help. Rehman 04:51, 16 March 2020 (UTC)

Notability of news articles

Today we create items for all journal articles out there, and try to link them together with each other (if they are used as a reference in another journal) and to their individual authors.

Currently, many journalists are notable enough to have Wikipedia articles about themselves, or at least a Wikidata item. Would it be inconceivable to create items for news articles as well, if either the author is notable, or it could be used as a reference in a Wikipedia article in some way (i.e. storing references as individual items on Wikidata).

Yesterday I created The Ministry of Foreign Affairs advises against travel to all countries (Q87727134) which is a news article from Sweden in Dagens Nyheter (Q1126918) written by Clas Svahn (Q6197220) that "The Ministry of Foreign Affairs advises against travel to all countries" and linked the main subjects Ministry for Foreign Affairs of Sweden (Q776570) and 2020 coronavirus pandemic in Sweden (Q84081576).

Is this notable for a Wikidata item, or am I "too much of an inclusionist"? (tJosve05a (c) 13:28, 15 March 2020 (UTC)

Too much. The news article doesn't seem to be notable nor required for structural purposes. --Tagishsimon (talk) 13:45, 15 March 2020 (UTC)
Well, we wish to have items for all of a book author's works. We wish to have items for all of a journal author's works. We wish to have items for all music artist's works. Why not notable journlaists as well? Especially if those work are being used as references on Wikipedia. (tJosve05a (c) 13:52, 15 March 2020 (UTC)
some inconclusive discussions:

--GZWDer (talk) 15:35, 15 March 2020 (UTC)

In my opinion if it is being used as a reference from Wikipedia then there is a structural need to have it in Wikidata so that it can be cited using Cite Q. Beyond this I would say you need to specifically identify what criteria from Wikidata:Notability you are satisfying and make some argument as to why it is satisfied. I would for example ask what serious publicly available sources can be used to describe it - Wikipedia would be one IMO, but if Wikipedia was not citing it then I would say there would have to be another. Iwan.Aucamp (talk) 15:48, 15 March 2020 (UTC)
  • Notability at Wikidata is to actually exist and have a link to show it exists. Our guideline states that it "[must] be described using serious and publicly available references". Saying "doesn't seem to be notable" has no meaning. We have a huge tranche of scientific articles that we imported. The argument for not including is always "now someone will import a billion news articles", well, no one wants to do that work, or they would have done it already. --RAN (talk) 18:00, 15 March 2020 (UTC)
It would probably be more useful to the general population than all the scholarly article items. --Trade (talk) 18:41, 15 March 2020 (UTC)
One of these scholarly articles might contain a cure for the cancer you may get in ten years. With news that probabiity is much less. --SCIdude (talk) 15:29, 16 March 2020 (UTC)

What should be an subclass of (P279) of a technical standard (Q317623) and what should be instance of (P31) of a technical standard (Q317623)

I want to import metadata for documents published by 3GPP, some example documents:

This however made me wonder about the appropriate structure, what organizational items should there be, what should be an subclass of (P279) and what should be instance of (P31) etc.

I have looked at current subclass of (P279) report (Q10870555), technical standard (Q317623) and specification (Q2101564) - and there seems to be somewhat of a lack of consistency.

The clearest guidelines for structuring information like this that that I can find at the moment is from Wikidata:WikiProject_Books#Bibliographic_properties.

Using the approach from WikiProject Books it would imply that.

This is rather similar to what is happening with ITU-T ITU-T recommendation (Q55935585) and ITU-T recommendation version (Q55936923) except that ITU-T recommendation version (Q55936923) subclass of (P279) ITU-T recommendation (Q55935585) which runs contrary to the WikiProject Books Guidelines IMO.

For example:

For other cases, like IEEE it is a bit of a mess really (not that ITU-T is not a mess). Similar to ITU-T there is IEEE standard (Q55755785) and IEEE standard version (Q55936932) but there is almost no consistency in how they are used with the following statements occurring:

I have analysed some other cases also:

I'm working on a detailed proposal for a 3GPP publication ontology here if someone wants to have a look.

This raises a couple of questions:

Any input on this matter would be appreciated. Iwan.Aucamp (talk) 20:50, 15 March 2020 (UTC)

If we were treating standards as documents with editions, then maybe a "technical standard" Q317623 is not really a form of written work equivalent to "novel" or "poem" or "technical report", since we want the editions to be the technical standards, not the "written work" item. Then these standards documents would be treated like other published technical reports, i.e., with a main item which is an instance of written work (Q47461344), or a subclass appropriate for technical reports, and the individual standards like C99 would be editions of that written work and also marked as "technical standards". The "technical standard" item would no longer be a subclass of "written work" or "document". Alternatively, maybe using editions would be a inappropriate, and each new version of the standard would be better treated as a written work in its own right. Ghouston (talk) 07:36, 16 March 2020 (UTC)
The way that C99 (Q1151257) is set up (ignoring the incorrect subclass statements than can be deleted) is not right, because it's an edition that's also an instance of a subclass of written work (Q47461344) (i.e., ISO standard (Q15087423)). Ghouston (talk) 07:50, 16 March 2020 (UTC)

Cookbook recipe properties for main ingredients and optional ingredients

Porridge in the microwave (Q87066630) is one of the Wikidata items I'm working on. The Wikidata item was created for the Swedish Wikibooks Cookbook("Kokboken") recipe item "Kokboken/Recept/Gröt i mikrovågsugnen". I want to have "main ingredients" and "optional ingredients" properties. Because in this recipe there aren't any blueberries based on the original recipe, though personally I wanted to add blueberries, so I added them as optional ingredients. Is it ok if I create 2 properties for my needs or is it better if I go to a proposal page and suggest community input? What is the best way to go about this?(if this experience doesn't lead anywhere and we just keep on discussing and discussing I think I'll take the risk and create 2 properties for my needs, just saying as I'm experienced with discussions at some instances not leading to anything productive). If you can connect others who are interested in English Wikibooks Cookbook and Wikidata, you are welcome. It might be proper for me to do the same. Datariumrex (talk) 08:57, 16 March 2020 (UTC)

Unless you're a property creator you cannot create new properties (and if you were you would not bypass the approval process like that). As for your question, I'm personally unfamiliar with modelling recipes, but see that you're using has part (P527). For optional ingredients you could qualify it with has quality (P1552) optional (Q59864995) (this item needs some details added, but seem to represent the right quality). That said, I personally think it would appropriate to propose a new "ingredient" property because a recipe itself is not made of ingredient parts (the relation is different than P527 in my opinion). --SilentSpike (talk) 10:03, 16 March 2020 (UTC)

Where should the image of an award received go?

Where should the image of an award received go? At Chester Bennett Bowen (Q5093459) the medal of honor is displayed for image=, I don't mind having an image for an award, but we need image=null to search for people that need portraits. Any suggestions where it can go, or just delete the image? --RAN (talk) 19:16, 16 March 2020 (UTC)

It could go on related image (P6802). Ghouston (talk) 22:33, 16 March 2020 (UTC)

Ways to mark possibly fictitious genealogy entries

Hi. Can anyone offer some advice on the best way to handle entries from genealogy databases that are believed to be fictitious? Sigrid of Halland (Q75437282) is recorded in The Peerage and WikiTree as the mother of Ulf the Earl (Q1710670) and previous editors have replicated the connection on Wikidata. Oleryhlolsson (talkcontribslogs) has removed the connection with the claim that the relationship is not supported by more reliable sources.[10] This is possibly a case of a speculative entry being created in one dataset on the internet and then migrating around the internet to other datasets.
We can't treat the connection as fact but what is the best way to handle the situation? If we delete the item, the disputed datasets will remain on the internet and a future editor will eventually recreate the same entry. If we blank the connection (as is the current position) another editor will re-establish the relationship in error through replicating the linked databases (this could also be done by bot edits copying data from the external databases with minimal oversight). If we record the relationship in our database then we are perpetuating and spreading the disputed record.
My view is that we need to retain the item but have some way to record the disputed nature of the claim. Are there any suggestions of alternate ways to handle this? From Hill To Shore (talk) 22:57, 16 March 2020 (UTC)

Seems like a prime use case for Help:Deprecation. Just need to add an appropriate reason for deprecation (P2241) qualifier. --SilentSpike (talk) 23:16, 16 March 2020 (UTC)

Hazard-Bot and Wikidata:Requests for deletions

Confusion with 3 properties

Consider the item Sanyathara (ID: Q16832086). She is an actress. Should this item be placed under actor, actor(actress) or actress? Adithyak1997 (talk) 17:17, 15 March 2020 (UTC)

I would place it under actor and I think that this is a good question and there is a solution needed. female form of label (P2521) is usually used in cases like that at the item about the occupation (P106) or position held to show the female label of the job. The current situation is not reader friendly. How the data users who download the dump or use data from a query work with this is not clear. I think it were good if there could be another label displayed as the main label at the Statements of the Template:P106 property if the gender of a person is female. Maybe also if the gender is divers. There I dont know how the property for that case is called. For queries it is from my point of view as a user with not big knowledge about SPARQL better to have one item for all genders. I dont know how I can write a query to get a list with all persons from a country with actor or actress as their occupation if there is a item for every gender. If there is a solution for that it were also good for me and then the other thing is not needed. --Hogü-456 (talk) 18:23, 15 March 2020 (UTC)
If you open this Wikidata item actor (Q33999) you will find "actress" under "Also known as". I think a query can have custom labels where you can input "actress" into the label and that way the query will display actresses the way you prefer. If you want a general change of the label, I suggest a consensus with maybe the Wikipedia article community or other related communities in relation to the English language Wikimedia projects. Datariumrex (talk) 09:16, 16 March 2020 (UTC)
@Datariumrex: If you mean actress come under the heading actor, then why is there a property called 'Actress'? Does it have any other usage? Adithyak1997 (talk) 13:22, 16 March 2020 (UTC)
There is not any such "property". I think you are confused. There is an ITEM actor (Q33999) which has an also known value of actress. There is no ITEM for "actress" apart from that one. There is no ITEM "actor(actress)". The actor (Q33999) ITEM is typically used with PROPERTY occupation (P106). To give you any more help, should it be needed, please provide at least URLs for the things you are trying to explain to us. thx --Tagishsimon (talk) 13:53, 16 March 2020 (UTC)

The item actress (Q21169216) is about actress and so it is not clear what item is the right one if there is an actress the item is about a female person with occupation actor. -- Hogü-456 (talk) 17:35, 16 March 2020 (UTC)

This item actress (Q21169216) is related to Italian Wikiquote "Attrice". actor (Q33999) also has an Italian Wikiquote "Attore". The Wikidata item for actress (Q21169216) only has 1 Italian Wikiquote link to Attrice, so if you are interested you could try to merge the two Italian Wikiquote articles about Attrice and Attore, then you can link the one Italian Wikiquote article to actor (Q33999). I suggest you use actor (Q33999) for occupation. It includes female actors. Datariumrex (talk) 19:16, 16 March 2020 (UTC)
Thanks for replying. @Tagishsimon: It was my mistake in considering 'item' 'as' a property. Adithyak1997 (talk) 06:19, 17 March 2020 (UTC)

Two VIAF items, can we link somehow?

The Railway Musuem in Belgrade, Serbia has two lisitngs in VIAF, I've linked to the Serbian library VIAF item, the GND one seems to also be about the same item. Not sure how to proceed with linking both of them... Oaktree b (talk) 20:47, 16 March 2020 (UTC)

The best method, according to previous discussion, is to link both VIAF ids, and ignore the constraint flag. Apparently this helps people at VIAF notice the problem and perhaps they'll fix it. If you want to try to take it up with them directly, email Ghouston (talk) 23:24, 16 March 2020 (UTC)

Case insensitive queries

How can I make a wuery case insensitive? E.g. the capitatlisation found in DOIs:

SELECT ?DOI WHERE {?DOI wdt:P356 '10.15347/WJM/2019.003'}

Try it!

Any ideas? T.Shafee(evo&evo) (talk) 02:46, 17 March 2020 (UTC)

@Evolution and evolvability:
SELECT  ?title
WHERE   { ?x dc:title ?title
          FILTER regex(?title, "web", "i" )

Try it! }

Will modifications to this one work? Adithyak1997 (talk) 06:25, 17 March 2020 (UTC)

@Adithyak1997: Hmm, that ends up being v.slow (>10 seconds). I saw this blog post on speeding it up but I'm not SPARQL-savvy enough to implement it! Any assistance appreciated! T.Shafee(evo&evo) (talk) 10:56, 17 March 2020 (UTC)
@Evolution and evolvability: There is no way to avoid using a (slow) FILTER if you are trying to do a case-insensitive string search in SPARQL. SPARQL literals are always case sensitive. If you are just searching for specific strings, it might be easier to use Wikidata's search than SPARQL (all string values are indexed in a case-insensitive fashion by the search engine here) - just use the search box on any Wikidata page. ArthurPSmith (talk) 18:12, 17 March 2020 (UTC)
So as SPARQL this would be:
SELECT DISTINCT ?item ?itemLabel 
  hint:Query hint:optimizer "None".
  SERVICE wikibase:mwapi {
    bd:serviceParam wikibase:api "Search";
                    wikibase:endpoint "";
                    mwapi:srsearch "haswbstatement:P356=10.15347/wJM/2019.003".
    ?title wikibase:apiOutput mwapi:title.
  BIND(IRI(CONCAT(STR(wd:), ?title)) AS ?item)
  FILTER NOT EXISTS { ?item wdt:P921 wd:Q202864. }
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
Try it! --Tagishsimon (talk) 19:08, 17 March 2020 (UTC)
@ArthurPSmith, Tagishsimon: Excellent - thank you! Works as expected. I can't claim to fully understand exactly what it's doing, but it certainly works in all the stress-tests I've tried it with so problem solved! I'm now using it within this [R] script in the qid_from_DOI function. T.Shafee(evo&evo) (talk) 23:37, 17 March 2020 (UTC)

Geographic data

While seeing geographical data on Wikidata connected to OSM a question arose that I am not able to answer: What data is best kept only on OMS and what OSM data do we want a Wikidata item for? Where is the border/limit between these two? How much overlap should there be between Wikidata and OSM?  – The preceding unsigned comment was added by Daanvr (talk • contribs).

I think instead of trying to find the exact universal line in the sand, it's better to just consider each individual case against the inclusion criteria of each project. As you're asking this on Wikidata, that just means following WD:N. --SilentSpike (talk) 15:55, 17 March 2020 (UTC)
@Daanvr:You're asking a very broad questions. Maybe you can be a bit more specific with some examples?
For example I've been connecting regions on Wikidata with OSM. So German (Q2734574) is connected with both ways. I'm using this for reverse geocoding.
In the Netherlands I think most municipalities and towns are pretty well connected, but we could even go one level lower and connect neighborhoods. At first that might not look so interesting, but if you combine that with the data from you can make all sorts of nice visualizations on the fly. The geodata would be on OSM, the statistics in CBS and Wikidata acts as the glue.
Related to this, I like as an example where data from different sources are combined. Multichill (talk) 18:02, 17 March 2020 (UTC)
I'm not an expert on what kinds of data are in OSM, or on what is (or ought to be) linked in Wikidata, but for my purposes I would say:
  1. Islands, lakes, rivers, mountains: all of them (whether we currenty have entities or not)
  2. Political / administrative divisions and subdivisions: all of them, down to individual cities, neighborhoods, and other settlements (whether we currenty have entities or not)
  3. Streets and railroad lines: no
  4. Buildings, bridges, other structures: no (unless they're particularly notable ones we already have entities for)
  5. Land cover: no
  6. Elevation and hydrography data: no
  7. Actual outline data for the entities in #1 and #2: yes, but only at the coarsest scale
Scs (talk) 20:09, 17 March 2020 (UTC)

I'm not sure if it's germane here, but in many cities, neighborhoods are a bit vague, and a definition given at OSM may or may not be objective/sourced/verifiable/etc. - Jmabel (talk) 00:08, 18 March 2020 (UTC)

Well, I'm trying to add[11] and it won't let me. Just now I can't even remove it from Q87470714. Both tell me my changes can't be saved. Usually magic elves come along and Wikidata poofs into existence on the pages I create on other projects, so I don't come over here too often; this has been straight forward in the past though. I'll try again after the workday and maybe try bugging those other project pages then. Thanks! -- Kendrick7 (talk) 12:29, 13 March 2020 (UTC)
Both are correct:
  1. One page can only be connected to a single item at a time (integrity check).

How many IDs will each instance of P1580 have?

If the data being added at Johann Sebastian Bach (Q1339) is any indication, then we may want to remove University of Barcelona authority ID (P1580). Witness

Either the property is useless because there are dozens of IDs for the same thing, or something about the University's interface is producing multiple false values. I mention it here in case similar issues with this property are appearing on other data items. --EncycloPetey (talk) 05:01, 17 March 2020 (UTC)

The IDs appear to have been set against the wrong items. For example, ID a1370581 is about Christmas Oratorio (Q642010) not Johann Sebastian Bach (Q1339). From Hill To Shore (talk) 11:57, 17 March 2020 (UTC)
@Magnus Manske: Your bot appears to be placing these wrong IDs on Johann Sebastian Bach (Q1339). Can you please investigate and implement a fix to your bot's behaviour? I suspect that any attempt to clean up the item will just be undone by your bot. From Hill To Shore (talk) 12:42, 17 March 2020 (UTC)
We may have to just block the bot. It's made the same mistakes again see and the last few messages I've posted to Magnus Manske about his bot have been met with replies that the bot is working fine and he will fix nothing. --EncycloPetey (talk) 16:02, 17 March 2020 (UTC)
Looking into it more, the bot may be functioning correctly. It is taking information entered into the "mix and match" tool and copying it to Wikidata. The problem lies in how to prevent the wrong data from appearing in the tool. I haven't encountered the tool before but I will investigate. From Hill To Shore (talk) 16:59, 17 March 2020 (UTC)
@EncycloPetey: I've manually updated all of the entries I could find in the mix'n'match tool, so those ones won't be restored. The bot will restore any that I missed though; don't remove them until you have updated their entry at mix'n'match or the bot will just revert you. The mix'n'match URL is in the bot's edit summary. If you are not sure what to do, I'll make the updates when I have time. I'll keep the page in my watchlist. From Hill To Shore (talk) 22:05, 17 March 2020 (UTC)

I have a related question on this. University of Barcelona authority ID (P1580) has been set with a constraint of human only, but we have found here that the ID is also used for creative works. I'm unfamiliar with altering propoerties. Do I just jump in and make a change or does it require discussion (as it is used on thousands of pages)? From Hill To Shore (talk) 22:22, 17 March 2020 (UTC)

The approval discussion said the property would be limited to persons. That should not be changed without discussion, but since the values are not limited to persons, it may call into question the original approval. --EncycloPetey (talk) 23:58, 17 March 2020 (UTC)

The bot continues to add multiple values and I've now seen bad values being added to other data items and for other properties. On data items where here I have checked, there have been more bad values added than good values. --EncycloPetey (talk) 14:56, 18 March 2020 (UTC)

Is there an automated way to reorder a list in Wikidata

At 1930 Ford National Reliability Air Tour (Q68255449) I have a list of participants in an event, I add the people as I figure out who they are and make an entry for them in Wikidata.

Hi! I was just going through the low-numbered items out of curiosity, when I found that Q6 does not exist. I looked at its public logs, and it apparently never did. Why was this number skipped? Was there a technical reason, a glitch, something lost when the servers changed at some point, etc.? DemonDays64 | Talk to me 13:49, 20 March 2020 (UTC) (please ping on reply)

I don't know the answer, but I've wondered the same thing about P1, P2, P3, P4, and P5. —Scs (talk) 14:17, 20 March 2020 (UTC)
Some Q numbers were reserved. Those that were created can be seen in the earliest contributions of Special:Contributions/, but others were not used, such as Q6. Higher numbers that were never created, such as Q26536624, were unsuccessful attempts to create an item, for example if name and description matched an existing item. I don't know about the properties, if any numbers were reserved there. Peter James (talk) 17:47, 20 March 2020 (UTC)
@Peter James: Why reservation was needed? Eurohunter (talk) 18:01, 20 March 2020 (UTC)
It wasn't needed, Wikidata:Humour explains (although not all in that list were reserved - when Q12321 and Q12345 were created it was possible to look at the newest items and create a new item that would probably have the next number). Peter James (talk) 19:33, 20 March 2020 (UTC)

Author= for anonymous news articles

For anonymous news articles Author=anonymous or Author=unknown_value or Author=no_value or Author=unknown or just not add an author property? --RAN (talk) 23:11, 10 March 2020 (UTC)

Definitely "unknown" (if it's actually unknown--if it's anonymous but we do know the author, include it). Anonymous authors are authors, so it's incorrect to say that there is no value, it's just a value that we don't know. —Justin (koavf)TCM 23:19, 10 March 2020 (UTC)
Please don't use "unknown". Writing is an art, even if done anonymously. For works by unknown artists, we use "anonymous". The problem with "unknown" on Wikidata is that it translates to "no value", so for example it could have been a chimpanzee. We know it was written by a human. Jane023 (talk) 08:14, 11 March 2020 (UTC)
@Jane023: No, it does not translate to « no value », which is a thing on Wikidata. Maybe some people interpret it that way, this is a mistake and they should be corrected and not maintained into a false belief. One big problem, I think, is to translate its own cultural judgement into Wikidata … translating « unknown » to « anonymous » is definitely a possibility at the data consumption step, for example in a query code or an infobox code. This does not mean that there is a need to use a special value « anonymous ». The fact that an author is usually human is represented in Wikidata … on the « author » property page, as a constraint (the domain constraint one). So « no », logically, this does not imply in Wikidata that the author can be a monkey. It implies in the Wikidata language that it’s probably a human. author  TomT0m / talk page 10:18, 11 March 2020 (UTC)
Thus my "Please", for all the reasons you gave. The word "anonymous" is often used for "unknown" as well as "known but desires anonymity". The convention in art historical terms is to use "anonymous". Jane023 (talk) 10:25, 11 March 2020 (UTC)
@Jane023: Wikidata does not have to use the convention, it just has to represent the fact that it has been published anonymously. We may need a qualifier or something like that, to be defined. But using a « special value item » is probably not the way to go. Imagine a query of all the text of different authors, for example, « anonymous » ( and also « some value » / « no value » but this is irreducible) would need special treatments for « anonymous » not being the most prolific author of all times … This is probably not the way to go. We need another representation and we can do better, maybe a qualifier or a property « publication mode » (values « anonymous », « pseudonymous ») or something like that, to denote voluntarily anonymous publication and this other kind of specificity.
This would have the advantage that if an anonymous author is later revealed and published, we can add the value to the statement without losing the fact that it was published anonymously. author  TomT0m / talk page 11:01, 11 March 2020 (UTC)
Exactly. Nice to see you're in agreement then! Jane023 (talk) 11:18, 11 March 2020 (UTC)
To be sure, my positition is use unknown value Help with some additional informations, probably in forms of a property that does not exist yet. Not « anonymous » as a value. author  TomT0m / talk page 11:26, 11 March 2020 (UTC)
  • The existing item anonymous (Q4233718) violates our ontology and as such shouldn't be used. Using it means that peoples will be told that two items are by the same author when that's not true. Author=unknown_value is the correct way to note the relationship. In case you want to add more information object has role (P3831) can be used to add them. ChristianKl❫ 19:19, 11 March 2020 (UTC)
  • I am really interested in reaching consensus on this and documenting that consensus as a best practice on our Help pages and in Wikidata:WikiProject Visual arts/Item structure (where the current recommendation is to use anonymous (Q4233718) when the creator (P170) is unknown). I would be most comfortable with unknown value Help with stated in reference as (P5997) "anonymous" in the references where that is the case, but I don't strongly care what the consensus is as long as there is one. I don't know what I ought to use and that bothers me. - PKM (talk) 21:00, 13 March 2020 (UTC)
@PKM: I like your suggestion. That feels like a rich way of modeling it. Ainali (talk) 21:22, 13 March 2020 (UTC)
  • Using an actual "anonymous" item instead of the special <unknown value> (with good qualifiers) is not really ontologically sound and would lead to data users having to create an unnecessary special case for this "anonymous" item or else that would become a really prolific nobody in data queries. —seav (talk) 09:57, 14 March 2020 (UTC)
  • "Author=unknown_value" is the best way to go. "Author=no_value" would mean an article without author (maybe if it's auto-generated? maybe a chimpanzee, but some may argue that animals do have author rights so not sure it fits). Author=anonymous (I'm assuming here "anonymous" is the item anonymous (Q4233718)) is not wrong per see but very tricky, it could lead to several problem, like believing a same person wrote text for millennia :/ (obviously, there is an exception for edge cases, like when the person is known but not their name, Master of the Saint Bartholomew Altarpiece (Q632385) for instance).

Oh no, we're having this discussion again! :-) I'm actually quite happy this is put forward again because it has been bothering me for a while. Wikidata is a wiki and a wiki works by consensus. Our current consensus for art is documented at Wikidata:WikiProject Visual arts/Item structure and is to use anonymous (Q4233718). Another aspect of a wiki is to try things, change things and improve things. As mentioned above, the current way of using anonymous (Q4233718) makes it harder to work with our data. It's a like an extra special value that is not easy to pinpoint. I think the source of the problem is what exactly some value means. The interface makes it look like "unknown value", but it's much broader than that. It's for everything where we know we have some value (as opposed to no value), but we don't know what that value is in our ontology or we know we don't have an item for that in our ontology and everything in between. Do we agree on this part?

I would love to switch to some value (yes, I prefer using that over unknown value) for art and particularly paintings. Yes, it will cost us some time to do conversion, but that has never kept us from doing much larger projects. In the current situation we use creator (P170) -> anonymous (Q4233718) and it might have some qualifiers. In the new situation we would use creator (P170) -> some value with qualifier object has role (P3831) -> anonymous (Q4233718) and whatever qualifiers we already have (and maybe stated in reference as (P5997) in the reference section).

I hope we can reach consensus here. I'll advertise this discussion in several places so people have the possibility to comment. Multichill (talk) 19:26, 17 March 2020 (UTC)

This impacts the rules for copyright in Wikidata as well as Commons. We have anonymous in the legal sense as 'first publication without the name of the author published' (70 years after publication rule for pseudonymous and anonymous works), and we have works were we are not sure of who the author is, as well we have works like old paintings without the name of the creator, but 'problably painted by' or 'school of', or 'master of'. For mass imports to convert all this kind of 'anonymous' to all kind of unknown values, this should be handled by special bots as we can't ask insitutions to convert their logic where those are identitities in their system to our logic. --Hannolans (talk) 20:08, 17 March 2020 (UTC)

Moved Jane's response here from Wikidata talk:WikiProject Visual artsMultichill (talk) 21:12, 17 March 2020 (UTC)
I am really very sorry to see that discussion take a wrong turn. If you look at the historiography of art history and attributions, you see attributions bounce around between non-names, anonymous, and various creators. The word "anonymous" is a standard, no matter what form of art it is. There is a very small group of works that are signed "anonymous" when the creator is in fact common knowledge, but to be clear, that is not the meaning that is currently the subject of the conversation. My opinion remains that using Marie Antoinette (Q47365) is the correct item to use in creator (P170) statements. Jane023 (talk) 21:01, 17 March 2020 (UTC)
@Jane023: I assume you meant anonymous (Q4233718) and not Marie Antoinette (Q47365). We're not removing anonymous (Q4233718), we're only moving it to the qualifier object has role (P3831). No data is lost. Multichill (talk) 21:37, 17 March 2020 (UTC)
Hello. Imho, the differents approachs are not necessary a problem, because it depends on the area of contribution. I must say on this question I even don't agree with myself. There are different and contradictory approaches:
  • ontologic approach
We don't know the creator, there is a way in Wikidata for this, so claim with "unknow" value. Discussion closed.
  • domain-based approach
Anonymous sounds absurd for ancient objects but for artworks it's very common.
  • approach according to art history and knowledge bases
In art history and in databases, especially in collection website, there is very often anonymous. It is even generally the case for modern visual artworks collection when creator is unknown. If Wikidata has vocation to base claims on knowledge database and references sourced, and to link knowledge data, so we maybe should preserve this approach. Jane023 is right to aware us on this point.
  • approach according to the historical notion of creator in visual art
It's a new version of the Quarrel of the Ancients and the Moderns! Not signing an atwork is the practice before Renaissance and after could be a choice, especially in painting. In the first case, the creator could be unknown and in the second the creator is anonymous. Both are true. That's why imho we have different approachs, depending on the area in which we contribute. The idea to associate a person (or several) to an artwork is now systematic for modern artworks and "anonymous" become the standard way to express it when a name is missing.
So, in Wikidata in artworks domain, we see this two differences in contributions on the main lines:
Creator:Unknow value until Renaissance
Creator:Anonymous after Renaissance
I think we should keeping things like this and for myself that's the ways I contribute, "Unknow value" for antiques, except rare exceptions, and anonymous for modern visual artworks.
And in others domain, like litterature, things could be different.

You seem to have missed the part about not removing anonymous, but moving it to a qualifier. Or at least you didn't address this point in your response. Multichill (talk) 09:12, 18 March 2020 (UTC)
I saw it. It's factually the unknow approach, called some value, with a complex and subtle add for anonymous. Imho it will be hard to understand, edit and link. For example if someone want to extract easily data on an artwork set with the creator. Wikidata is made to be reused and unfortuntely for outside I doubt that such statements makes the journey. Best regards --Shonagon (talk) 09:44, 18 March 2020 (UTC)

OK for the record I would approve using Marie Antoinette for anonymous! Just kidding. As I see it, the problem is with how we expect queries to behave after implementation. We either expect Mr. Anonymous aka Marie Antoinette to have millions of works, or we expect to have millions of works by unique, nameless individuals. Neither is optimal, but since the historic literature (i.e. book indexes including entries for "anonymous") chooses anonymous, this is the easiest and least ambiguous way to do it. You can always put lots of qualifiers on any item of course, and I have considered making items for "Circle of Rembrandt" where I make it instance of not-name, but give it members (all pupils and colleagues of Leiden and/or Amsterdam). Jane023 (talk) 10:00, 18 March 2020 (UTC)

I would definitely support switching from anonymous to somevalue. That is really what we aim to express here, and Wikidata is more concerned about meaning that about words. I am actuually not sure about the use of anonymous (Q4233718) in qualifiers actually. Note that "anonymous" has at least two, essentially opposite meanings that may require two different items:
  • a work whose creator's name has not beed passed down to us, but was known at the time. Say a sculpture in a gothic cathedral.
  • a work whose creator was originally undisclosed but may have been revealed later, say some political pamphlets or Frankenstein (Q150827). -Zolo (talk) 08:49, 19 March 2020 (UTC)

Apart from the ontological discussions, consider a practical implication: the blank nodes used in "unknown value" cause significant reduction in Wikidata's update rate capacity: I vote to use "anonymous" --Vladimir Alexiev (talk) 09:44, 19 March 2020 (UTC)

age at event (P3629)

age at event (P3629) should be aloved for any information especially for this information whose date is unknown like beginning of musical carrer etc. Eurohunter (talk) 18:33, 18 March 2020 (UTC)

@Eurohunter: I can't see this property in your recent contributions. Can you please give some more information about: what you tried to do; what you expected to happen; and what happened instead? Cheers, Bovlb (talk) 19:59, 18 March 2020 (UTC)
@Bovlb: Basshunter (Q59437791) Eurohunter (talk) 20:38, 18 March 2020 (UTC)
@Eurohunter: Ah. I see that Basshunter (Q59437791) is a stage name for Basshunter (Q383541). I think I would expect to see age at event (P3629) used as a qualifier on a significant event (P793) claim on a person. If you used in on a stage name, would it refer to the age of the underlying person or the age of the stage name? Bovlb (talk) 20:49, 18 March 2020 (UTC)
@Bovlb: I thought it will be obvious that age with start time (P580) would mean age of person during occurrence of event (age of person which started using stage name in this case). Eurohunter (talk) 20:55, 18 March 2020 (UTC)
@Eurohunter: Let me see if I understand what you are saying. You want to give a stage name a start time (as in the time that the underlying person started using that stage name), and further qualify that claim with the age the person was (stated to be) at the time. Is that right? Bovlb (talk) 21:15, 18 March 2020 (UTC)
@Bovlb: Yes Eurohunter (talk) 12:40, 19 March 2020 (UTC)
@Eurohunter: OK. I think it would be more natural to represent that on the person, but all it seems redundant when we know the date of birth of a person.

Mark an Item for check

Hello, I am interested in Ambassadors and other public positions and I try to get an overview about them. The Label of the following item is not the full one and I want to change it. ambassador of Germany to Switzerland (Q22230846) is about the ambassodor of Germany in Switzerland. It also serves for Liechtenstein and this is included in the full title but not in the label of the item. In cases like that I am not able to change all labels in the different languages. Is it possible to mark items like that one, that other people can help me by translating the labels. I know that there are some filters and lists out of these filters. I think that after the number of items who hit a criteria is at some filters high it is then not easy possible to look them through. How should things like that be handled. -- Hogü-456 (talk) 21:14, 18 March 2020 (UTC)

Can't answer the question about labels. The change you're proposing is worrying. It only makes sense if all German ambassadors to Switzerland were at the same time German ambassadors to Lichtenstein, without exception. Are you sure this has always been the case, for all items on which we use the value? If not, then adding a new "German ambassador to S & L" would seem to be the way to go, rather than changing the meaning of the existing item. Changing meanings of items should always ring alarm bells; occasionally the change will better reflect the thing being modelled. More often it does unimagined damage. --Tagishsimon (talk) 23:28, 18 March 2020 (UTC)
I know that this is the case. There is since the begin of the diplomatic mission of the Federal Republik of Germany in Switzerland 1951 the same ambassador also serving for Liechtenstein. --Hogü-456 (talk) 16:42, 19 March 2020 (UTC)
Yes, but the German Wikipedia lists German ambassadors to Switzerland since the 1800s. A simple name change could also imply the 1800s ambassadors also covered Liechtenstein. From Hill To Shore (talk) 17:39, 19 March 2020 (UTC)
Here is one that would be affected; Otto Bülow (Q15837959). He is linked to ambassador of Germany to Switzerland (Q22230846) but died in 1901. As already suggested, if you can source the combined name as current, then create a new item for it and migrate the relevant people to the new item. That will leave the older entries still pointing to the correct name. From Hill To Shore (talk) 18:00, 19 March 2020 (UTC)
As you tell me I need to pay more attention in cases like that what happens throug my change and it is an example that it is not easy use the right item. There were other states before the Federal Repubublic of Germany and so the example uses at the moment a not correct item after Federal Republic of Germany started in 1949. For the periods before 1951 and the positions there I create another items. These are not the same positions.Is it right that there should be an own item for every position or when is a new item needed. For example if a minister gets further tasks and his title is changed through that. Is then a new item needed. It is not in every case clear what the official title is and usually the normally used title is not the full official title. Defining a correct label in different languages is not easy and if the number of positions describing mostly the same thing from usually used title increases then there should be a solution to find all these items. Is there a efficient way to search for aliasses. --Hogü-456 (talk) 20:17, 19 March 2020 (UTC)

Codes of lanuages

It's not the first time I saying it but it's impossible to obtain lanuage code from list of headers (labels) so If you see certain language in one item you are unable to add the same language to other item because you don't know its code. The only way to get them is to "provoking" edit/make "empty" edit of lasbels so their codes appear in item history. Eurohunter (talk) 21:02, 18 March 2020 (UTC)

You may be interested in the labelLister gadget. See Special:Preferences#mw-prefsection-gadgets. Bovlb (talk) 21:19, 18 March 2020 (UTC)
@Bovlb: I have it enabled but it don't do any difference. Eurohunter (talk) 12:27, 20 March 2020 (UTC)
@Eurohunter: Do you see a tab between "Read" and "View history" that says "Labels list" (depending on your interface language, of course)? When you click on it, do you see a table with language codes at the left?
An alternative, but somewhat more fiddly way to get label language codes from an item is to use the JSON view. E.g. for Basshunter (Q383541), change the URL to (does someone have a gadget to add a link for this?) and examine the "labels" section. (You may want to install a "JSON Viewer" extension on your browser.)
A third way would be to use SPARQL. Bovlb (talk) 15:33, 20 March 2020 (UTC)
@Bovlb: There are languages names "French", "German" etc. but there are no their codes "fr", "de" and vice versa with Json. Eurohunter (talk) 16:32, 20 March 2020 (UTC)
@Eurohunter: Hmm. Are you using the released version or the beta version? (I see the beta version has only language names.) It should look like this image.
Bovlb (talk) 16:42, 20 March 2020 (UTC)
@Bovlb: But there is no language name so it's pointless. There neeed to be both language name and their code somewhere. Eurohunter (talk) 16:52, 20 March 2020 (UTC)
@Eurohunter:. OK. I did not know that you needed both language code and language name, as you just asked for codes. You might like to make a feature request at MediaWiki_talk:Gadget-labelLister.js. In the meantime, here is a SPARQL query that might meet some of your needs. Bovlb (talk) 17:23, 20 March 2020 (UTC)

Modelling sections and stages of hiking trails

Hi. I love hiking trails and work in OSM mapping them. There exist a lot of data about the different stages, their length, connection to other trails, whether you can bring a wheelchair, whether there is accomodation in each end of the stage, e.g. Currently none of this data is modeled in WD it seems. See e.g. Kungsleden (Q59780). This particular trail also has 5 sections [12] which are subdivided into sections e.g. [13]. Would it be acceptable to create a Qitem for every section and stage to model this data? WDYT?--So9q (talk) 13:05, 20 March 2020 (UTC)

Yes. This is already done. See North Cascades National Park/Ross Lake NRA segment of the Pacific Northwest Trail (Q27895202) for an example. Otherwise, there is a list of useful properties here. Thierry Caro (talk) 16:02, 20 March 2020 (UTC)

Intentional sitelinks to redirects don't seem to work

Hi again! I just made Legion (Q88081101) and was trying to give it a sitelink to the redirect page wikipedia:Legion (novella) (which redirects to a page that has an item linked to it), but an error happens. Above the place where I typed in the sitelink, it says:

Could not save due to an error.

The save has failed.

This happens repeatedly, and with attempts to link different items to redirects. The very confusing thing is that you can mark a sitelink as an "intentional sitelink to redirect".

Is this a bug or an intended design to stop redirecting sitelinks from being added? Thanks, DemonDays64 | Talk to me 14:36, 20 March 2020 (UTC) (please ping on reply)

I think I remember that it's intentional to prevent redirects from being added, but could be wrong about that. I think you can only link to a redirect if you link to a non-redirect page and then change it into a redirect. In the mean time, I've linked the book item to the series item. -- Ajraddatz (talk) 15:13, 20 March 2020 (UTC)

Please protect Q1339

It looks as though someone has made multiple erroneous requests for Reinheitsgebot (talkcontribslogs) to add incorrect values to Johann Sebastian Bach (Q1339), using CERL Thesaurus ID (P1871) and University of Barcelona authority ID (P1580).

From Hill To Shore (talkcontribslogs) cleared out many of these, but the bot keeps adding new values; values that are for works instead of the person, and values that are for other people. I have also requested help from Magnus Manske (talkcontribslogs), but he insists his bot is doing what it is supposed to be doing and will not help. --EncycloPetey (talk) 20:29, 18 March 2020 (UTC)

@EncycloPetey, Magnus Manske, From Hill To Shore: I fully protected Q1339 for a week. Here's hoping that the issues with the addition of faulty identifiers can be addressed before that week ends. Any other admin may undo this full protection, but I insist that they first consider whether the aggregation of that many errors on a single item is appropriate to allow. Mahir256 (talk) 21:05, 18 March 2020 (UTC)
@EncycloPetey: Can you please link to the relevant conversation with Magnus Manske ?
It doesn't seem like fully-protecting an item is the right way to respond to a problem like this. Do we have any reason to suppose that the problem is limited to one item?
If this bot is just proxying edits for a Mix'n'match user who is logged in through OAuth, then why are the edits not credited to the user? Bovlb (talk) 21:08, 18 March 2020 (UTC)
(after edit conflict) From all the ones I fixed so far, they appear to have been auto-generated in mix'n'match in 2016. I don't think protecting the page will be productive here. The only way I have to find what needs fixing is through the bot importing the old and incorrect data. As soon as protection expires the bot edits will continue. However, if someone more knowledgeable on mix'n'match is able to produce a data dump of all entries pointing to Johann Sebastian Bach (Q1339) then we can work through resolving the errors before the protection expires. From Hill To Shore (talk) 21:23, 18 March 2020 (UTC)
I've now found how to see every entry linked to a Q at mix'n'match and am breaking the links from bad items where I find them. For some reason the tool has automatically matched a large number of entries simply because they have a first name of Johann (or similar). God knows the quality of data being imported across the project if this is the quality of matching. From Hill To Shore (talk) 21:54, 18 March 2020 (UTC)
@Bovlb: I don't know how to link to the sort of talk page threads used on his talk page, but the most recent conversation about this kind of problem is titled: "Bad LoC data link". And no, this isn't limited to just Johann Sebastian Bach (Q1339). Other recent instances of similar bad data being added are [21], [22], but for these other instances, only a single bad data value was added. For Johann Sebastian Bach (Q1339) it is a flood of bad data, and hence we've now had two threads in Project chat trying to resolve the problem. --EncycloPetey (talk) 21:19, 18 March 2020 (UTC)
Ah. I see this thread above, and also Topic:Vinm5yw46zr6f1r0 (select "permalink" from the "..." menu on the right).
I still don't understand why we have tools that make changes on behalf of users without identifying them. See also this thread. Bovlb (talk) 21:27, 18 March 2020 (UTC)
Indeed. Neither is the User identified in the edit comment, nor is the link active to the Mix'n'Match tool. So, I have to copy-paste the link to another window to access the edit request page, and then manually remove the action item. --EncycloPetey (talk) 21:40, 18 March 2020 (UTC)
I started a thread about requiring proxying bots to attribute edits to a specific user. My view is that either botops should be responsible for their bot's edits, or they should indicate who is responsible. The third path we're on here, where the botop won't take responsibility, but there is no-one else to blame, does not seem defensible. Bovlb (talk) 21:59, 18 March 2020 (UTC)
Good grief. Protecting an individual entity isn't just a bad/ought-to-be-unnecessary idea, it sounds like it's not even sufficient, if there are unknown numbers of other entities also being affected.
Seems to me we just have to temporarily stop the bot! I'm not blaming the bot or its owner, but until we can properly vet the input, the bot is doing more harm than good. —Scs (talk) 21:59, 18 March 2020 (UTC)
I would have thought that it would have been exceptional for a bot adding identifiers to add more than one value for a specific identifier property to a specific item (and perhaps vice versa). It appears that this bot has been adding multiple values to Johann Sebastian Bach (Q1339) since 2016-04-04T09:53:55‎, when it added dozens of National Library of Israel ID (P949)s. Bovlb (talk) 22:13, 18 March 2020 (UTC)

I think I have managed to clear out all of the bad entries for Johann Sebastian Bach at mix'n'match (assuming the search returned all of the linked entries), so the page protection can probably be lifted (the bot will probably still try to load in the remaining valid entries). However, that doesn't address the wider problem. From Hill To Shore (talk) 22:15, 18 March 2020 (UTC)

Clarification which one is correct bronchial epithelial cell (Q30029740) instance of (P31) cell (Q7868) or bronchial epithelial cell (Q30029740) subclass of (P279) cell (Q7868) - and how can we make it easier for people to understand.

So me and @Eihel: is having a bit of a disagreement - I think this statement is correct bronchial epithelial cell (Q30029740) subclass of (P279) cell (Q7868) from my understanding from Help:Basic_membership_properties. Eihel thinks bronchial epithelial cell (Q30029740) instance of (P31) cell (Q7868) (or even bronchial epithelial cell (Q30029740) instance of (P31) anatomical structure (Q4936952) as it is now) is correct. Can we get some other inputs here, and can we maybe make a list of incorrect uses of instance of (P31) and subclass of (P279) - I started one here but I think we can put it in a better place Help_talk:Basic_membership_properties#Examples_of_incorrect_use.

How to model closure of a venue/business/amenity due to COVID-19?

What is the best way to model closure of a venue/business/amenity due to COVID-19? Some ideas:

  1. state of use (P5817) temporarily closed (Q55653430) with qualifiers has cause (P828) 2019–20 COVID-19 pandemic (Q81068910), announcement date (P6949), start time (P580) and end time (P582).
  2. significant event (P793) temporarily closed (Q55653430) with qualifiers has cause (P828) 2019–20 COVID-19 pandemic (Q81068910), announcement date (P6949), start time (P580) and end time (P582).

For borders, I've started to update such as Mexico–United States border (Q1057263). Bouzinac (talk) 15:57, 21 March 2020 (UTC)
I suggest a new property may be useful in relation to borders, one that is based on and allows modelling of restrictions against freedom of movement (Q1344824). The property could perhaps be broad enough to allow modelling of access restrictions to cross borders, enter buildings, participate in events, etc. Qualifiers could include:
  • prerequisite (P4967) or new property to state which visa, permit or other documentation may be required.
  • applies to people (P6001) to state that the access restriction applies to a particular group of people (by profession, citizenship, etc).
Dhx1 (talk) 16:23, 21 March 2020 (UTC)
Yes, I wish I could query the current closed borders and map their (red) lines... Timatic might help on this topic. @Twofortnights:, is there any dataset/database that could be useful to modelize (for instance US normally require Europeans an Esta, North Korean people cannot enter South Korea etc) Bouzinac (talk) 17:52, 21 March 2020 (UTC)

Hmm. I think it would be more logical to add the same value (e.g. "Macedonians") multiple times, with a single population and point in time qualifier in each. It makes no sense to have the qualifiers as "parallel arrays" as this is lost in the RDF. Bovlb (talk) 21:11, 21 March 2020 (UTC)
Yes, you need multiple of the same value with differing qualifiers. Then set the preferred rank on the most recent claims. --SilentSpike (talk) 22:37, 21 March 2020 (UTC)

Also, on a second look, I don't think P172 should be used as a main claim like this. It's intended to link the ethnic group of the subject (item the statement is on). Unsure how best to capture population ethnicity breakdown like is trying to be done here, but the main statement should almost certainly be P1082.

minimystery wrt quantity display

Take a look at millimetre (Q174789). For me, at least, the values of conversion to SI unit (P2370) and conversion to standard unit (P2442) are showing the associated units as raw Q-numbers, not as labels as they usually do. But this is not happening for other units (or other quantities elsewhere), just for Q174789. How could that be?

Date of baptism and religion, continued

From Wikidata:Project chat/Archive/2020/03#Date of baptism/religion. In that discussion, I suggested it was not a good idea to have the constraint asking for religion when adding a date of baptism. Is it going to be removed? I'm not the only one who expressed doubts about it, although the discussion is not resolved yet. I think this is a case of "when in doubt, leave it out" Levana Taylor (talk) 14:27, 20 March 2020 (UTC)

  • You are baptized into a specific religion, if you switch religions, then use the start and end date. If you know the baptism date, then you know the religion. --RAN (talk) 16:31, 20 March 2020 (UTC)
  • Not necessarily. I have seen sources that say a person was baptised on a particular date but don't mention a religion. Usually these are records from very long ago and you can infer the religion due to one being dominant in that particular state. For example, if someone from England was recorded by a source as baptised in 1553, the odds are very good that they were Christian (though whether Protestant or Catholic is less certain). While the religion can be inferred, you can't really put a reference against it. From Hill To Shore (talk) 18:23, 20 March 2020 (UTC)
This may be a European-American cultural difference! I have talked to some people in Germany who say "I'm a Lutheran, I suppose, anyhow that's what I was baptised and what's on my papers, not that I ever go to church." Whereas to me as an American it seems like religion is a matter of belief and you're misrepresenting someone by stating they have a certain religion if they don't actually practise it. So I would rather not run the risk of making a false claim about someone by putting in a "religion" statement, unless you actually know something about their adult beliefs. Again, I say, err on the safe side and omit the religion statement ... Levana Taylor (talk) 22:24, 20 March 2020 (UTC)
If you have evidence of baptism and the related religion then we should insert the appropriate religion. It is a correct statement that they were part of that religion when baptised. If you have evidence of different adult beliefs then set qualifiers for religion with a start time of baptism and end time of when your source says (use "latest date" if your source of alternative belief doesn't say the specific date of change). From Hill To Shore (talk) 22:37, 20 March 2020 (UTC)
I disagree with that. Almost always you are not going to know an end date or any positive information about their actual beliefs, leaving to be inferred that they kept the same religion all their life -- I just don't want to run the risk of misrepresenting someone like that. "Don't know" should always be clearly marked as "don't know." So how about this? Have a property "religion of childhood baptism." That says exactly no more than what it says. Levana Taylor (talk) 22:45, 20 March 2020 (UTC)
"Don't know" is definitely the wrong stance here. If we have a reliable source that states something at a point in time, then we do know. It would be misrepresenting them to say otherwise. Denying a sourced religious belief (even in childhood) is just as damaging as implying an unsourced religious belief in adulthood. A new property could work if it gets broader support. One issue you may have with your philosophy though is when do you draw the line? Hypothetically, we get the new property and say someone was baptised a catholic before their first birthday. We then get another source that says they were still going to church at the age of 10. In your view would it be okay to use the Religion parameter then, or is it also invalid as they are still a child? Unless you can clarify your position on the age when you are willing to accept someone's belief as sufficient evidence for usage on Wikidata, a new parameter is only going to be a patch on the problem. From Hill To Shore (talk) 23:00, 20 March 2020 (UTC)
Baptism shortly after birth may tell you something about someone's parents' religious affiliation or beliefs, but I don't see how it can tell you anything about their own. Do we also (for example) consider Mormon baptisms of the dead to retroactively make people Mormons, even if the religion didn't yet exist in their lifetime, or if they were (for example) Jews killed during the Holocaust? Obviously, an adult convert who gets baptised is normally an entirely different matter, but even there: what about mass baptisms by the priests who accompanied the Conquistadors? Did that really turn a bunch of American Natives into Catholics?
In a similar matter: as an atheist of Jewish ancestry, I am certainly a Jew by Halachic law, and I'll even help out my religious friends when they need an extra adult male Jew for a minyan, but that doesn't change my religious beliefs or affiliation. - Jmabel (talk) 23:09, 20 March 2020 (UTC)
I have no personal view on religious beliefs as I am approaching this from the impartial position that we should reflect the source material as best we can. If we have a fact from a reliable source, we should not be deleting it because it makes us uncomfortable. Instead of deleting, as a bare minimum we should be deprecating the statement with a qualifier that we need more sources to support it (possibly cannot be confirmed by other sources (Q25895909), possibly invalid entry requiring further references (Q35779580) or not been able to confirm this claim (Q21655367)). One thing I've noticed is that we have yet to link to the property in question; religion (P140). Now it may not be the case with every language, but several of the descriptions that I can interpret say this property includes those who are "associated" with the religion. The very act of being baptised establishes the association. If you want to convert the property to a meaning of "confirmed belief" or "confirmed affiliation," then that would support your argument. The change in property would need a broader discussion though. From Hill To Shore (talk) 23:30, 20 March 2020 (UTC)
To "reflect the source material as best we can" would be to state just that the source material exists without adding any additional assumptions or inferences. As was pointed out in the previous iteration of this discussion, sometimes parents are compelled to acquire documentation from their locally dominant religion even if they don't believe in it. Now, there's an argument to be had regarding religion as a collective social phenomenon, which we can talk about someone's participation in while avoiding inquiring into their internal thoughts, but that's a subtle argument that Wikidata editors should not have to think about every single time they enter a baptism date! No, there should just be a property (independent or as a qualifier) indicating what religion the document is for, end of matter. That is indisputably factual in anyone's eyes. Levana Taylor (talk) 07:31, 21 March 2020 (UTC)
A new parameter won't fix the problem unless you also gain consensus to reduce the scope of the existing parameter. So long as "association" is the threshold for adding religion (P140), it is, to use your words, indisputably factual that the baptism has established an association. Unless you are offering to patrol every single addition of religion (P140) in the database, a clarification/reduction in scope of the existing parameter is the only way to achieve your goal. From Hill To Shore (talk) 09:13, 21 March 2020 (UTC)
  • Would it be possible to use religion (P140) as a qualifier on date of baptism in early childhood (P1636)? To me, it doesn't make sense to consider a baby as following a particular religion, even if a religious organization may consider them a member. Ghouston (talk) 02:39, 21 March 2020 (UTC)
  • Further to the discussion above, to achieve the intended outcome, you will need to separate the threshold of "association" from religion (P140). Tinkering with the scope of an existing parameter is a bad idea as it changes the interpretation of every item it is currently linked to. Instead, I would advise gaining consensus to split the single parameter into separate parameters and then deprecating the original. You can have your "Religion of baptism" as one parameter but we would also need a "Practised religion" for where there is evidence of continued involvement. We could also have "Professed religious belief" if desired. We would certainly need a property for "Associated religion" but with a constraint that it can't be used on human items; that will allow items about buildings or artifacts to still be linked to the related religion. From Hill To Shore (talk) 09:33, 21 March 2020 (UTC)

Define religion in this context. Is it just christian, muslim, hindu, buddhist, pastafarian etc, or should it somehow differentiate between some fractions of those cults, like shiite vs. sunni, or catholic vs. protestant, or even further down the schisms, down to the en:The People's Front of Judea kind of infighting? Grüße vom Sänger ♫ (talk) 10:20, 21 March 2020 (UTC)

Instances of religion (Q9174). ChristianKl❫ 14:50, 21 March 2020 (UTC)
I fail to see the list of allowed religions, and on what level of differentiation this should be put to the items. Where is it hidden? Grüße vom Sänger ♫ (talk) 17:19, 21 March 2020 (UTC)

Um, let me refer back to the actual issue in question which is in danger of getting lost: The point was the constraint recently added to date of baptism in early childhood (P1636) "An entity with date of baptism in early childhood should also have a statement religion." Now, since we have seen that the issue of stating a person's religion is complicated and contentious, why have this constraint, forcing people to confront the vexed question every time they enter a baptism date simply as proxy for birthdate? No no no. Levana Taylor (talk) 11:30, 21 March 2020 (UTC)

When we say that a person's occupation is "laywer" without specifying anything about when that's true, we are saying that there was at least some time in the life of the person where they were a laywer. We aren't saying that they were a lawyer with 10 years. There's no false statement if we have statement that someone's religion is X if it was at some time and their lives and not other times of their lives. ChristianKl❫ 14:50, 21 March 2020 (UTC)

I think Levana Taylor (talkcontribslogs) has this exactly right. The religion should be a property of the baptism, not of the person. The person's religion is a separate matter. ChristianKl (talkcontribslogs), as has been made clear by several examples she an I have brought forward, it is quite possible for someone to have been baptised into a religion that neither they nor their parents ever subscribed to. To underline with an obvious example: even if you were "free evangelical" in 19th-century Norway, you still had to have your children baptised in the State church. - Jmabel (talk) 17:31, 21 March 2020 (UTC)

Thanks to Jmabel for the examples. Those provide concrete instances in which, if the religion on a person's baptism record was simply added as a "religion" statement with no restriction, that would constitute introducing bad data into Wikidata. Levana Taylor (talk) 12:16, 22 March 2020 (UTC)

Given that the new constraint under discussion is considerably controversial (in the two iterations of this discussion I count three people definitely opposed), why hasn't it been removed yet? The proper order of actions with a disputed new addition is not to add it until it's been agreed on. Levana Taylor (talk) 12:16, 22 March 2020 (UTC)

Quickstatements - forking proposed

Hi. QS is a valuable tool used by a lot of people daily to import large quantities of statements. Unfortunately it receives very little love from developers since the rewrite some time ago.

A quick glance at the list of issues and the lack of communication there tells me that Magnus has moved on to other ideas.

I would like to help with a fork but I'm not sure I can pull it of alone so I write this instead to ask if others are up for joining together.

Personally I would like to help add full lexeme support and add a feature to give user a popup and ask if a new value should be created when an exact match of subject-object is found ([feature request], [example of the mess it results in]). @MagnusManske:--So9q (talk) 08:55, 22 March 2020 (UTC)

There are some statements relating to cell (Q7868), cell type (Q189118) and anatomical structure (Q4936952) that seem a bit odd to me and I would appreciate if others can confirm if it makes sense or if something should be fixed.

Currently the following statements exists:

I have looked a bit at other first order metaclasses and it is hard to say if what is happening this is correct. I have also looked for guidelines or explanation of how to use metaclasses and all I can find is Wikidata:WikiProject_Ontology/Modelling.

Specific cases where I would say metaclasses are being used more correctly (don't take this as an endorsement of all statements):

And of course taxon (Q16521) seems right:

If I had to sum up what my main problem is with cell (Q7868), cell type (Q189118) and anatomical structure (Q4936952) is that we have items which end up both subclasses and instances of the same item - which I would say should not happen - or at least in this case does not make a lot of sense to me.

I am not entirely sure about all of this and I don't want to go around breaking things. I would appreciate other opinions on the matter. If we could declare that some specific use of metaclasses are correct and maybe give some examples of incorrect use and why it is incorrect it would be great.

Actually in Wikidata:WikiProject_Ontology/Modelling there is the quote "An item should not be both an instance of and a subclass of the same class" - so this would suggest that what is happening with cell type (Q189118) and anatomical structure (Q4936952) is wrong.
But if that is the case there is something wrong with the example there also because Honda Accord (Q463632) instance of (P31) automobile model (Q3231690) and transitively Honda Accord (Q463632) subclass of (P279) automobile model (Q3231690)
Iwan.Aucamp (talk) 11:32, 22 March 2020 (UTC)
  • I agree that we currently do't have a consistent way to model the ontology of anatomy and it would be great to have a consistent model. I'm not sure whether solving the problem one-item-at-a-time is the best way to go about it. I think we need more fundamental agreement.
We currently have no policy page that defines what we mean with first-order metaclass (Q24017414). To have a clear and consistent way the concept is used throughout Wikidata, it would be best to have an RfC that defines a clear usage for it.
In absence of a more global policy we could have a policy for anatomy, but I think it would also make sense to write this into a help page at project anatomy instead of solving the problem one-item-at-a-time.
I currently have a policy draft at feel free to contribute or write drafts on your own. ChristianKl❫ 12:16, 22 March 2020 (UTC)

Queries for problematic items and statements

I vaguely recall seeing some list of queries which highlight items with problems. I thought it was under Wikidata:SPARQL_query_service/queries/examples but I don't see it there now. I did find this page that has some queries which would highlight wrong items Wikidata:WikiProject_Ontology/Problems but I would like to know if there are more pages like it.

WikiProjects and equivalence

Are WikiProjects on Wikipedia and Wikidata considered one entity? Take for example WikiProject Books (Q8487081) - this links to both the Wikipedia project and Wikidata project. There are other items though like WikiProject Ontology (Q60005226) which is Wikidata specific and then other projects which are Wikipedia specific such as WikiProject Wikipedia-Books (Q15771636). Should we distinguish WikiProjects depending on the wikimedia project they fall under? Iwan.Aucamp (talk) 15:28, 22 March 2020 (UTC)

Further, I tried earlier to use Template:Ping_project with ping Wikidata:WikiProject_Law but this did not work:

Regarding WikiProject Law: {{Ping project}} works only with the wikiprojects in which finds a subpage /Participants, Wikidata:WikiProject Law didn't have one; now I've created it, so it should work. --Epìdosis 15:41, 22 March 2020 (UTC)

Indian cinema personalities


I work in a film archive as a cataloger. During these years, I have to come across lot of names of Indian film personalities in my records. For convenience, I have been preparing a spreadsheet with all the names with their variations. Trust me, in India there are a lot of variations of names.

As a result, I am now thinking to develop somewhat a Name Authority project for Indian cinema personalities in Wiki data so that a unified common name index is available online for users.

Please guide me with the steps to achieve the same.

Thanks!  – The preceding unsigned comment was added by Murchana (talk • contribs) at 17:39, March 18, 2020‎ (UTC).

@Murchana: You'll notice that for example on Dilip Kumar (Q377789) there is an "Also known as" field. This can be filled in with as many variations of the name as you like. Wikidata does seem like a good place to do this. There may also be specific properties that are relevant for this like pseudonym (P742), birth name (P1477), and others listed at Wikidata:WikiProject Names/Properties. ArthurPSmith (talk) 19:10, 18 March 2020 (UTC)

Is death in battle the same as killed in action?

death in battle (Q18663901) vs. killed in action (Q210392) the same or is one reserved for civilian deaths? If so please adjust the Description.--RAN (talk) 05:22, 22 March 2020 (UTC)

The german term is "In der Schlacht getötet" vs. "Im Einsatz getötet", thus {{Q|Q18663901} is restricted to the war, while killed in action (Q210392) is for all occupations, as someone dies while doing their duty (Fire brigade, soldier, doctor... Grüße vom Sänger ♫ (talk) 08:58, 22 March 2020 (UTC)
At the moment, though, most of the descriptions I see in most languages on killed in action (Q210392) seem to confine it to military situations as well, just not necessarily battle. I think we should either expand that to firefighters, police, etc. or have a distinct parallel item for those non-military occupations, if we do not already have one. - Jmabel (talk) 19:26, 22 March 2020 (UTC)

Merge help request: fingerpaint (Q67649265) and finger painting (Q353262)

Greetings and felicitations. I've read Help:Merge and have the gadget activated, but I am still uncertain if I should merge the two items (fingerpaint (Q67649265) and finger painting (Q353262)), and which item should take priority. —DocWatson42 (talk) 00:04, 25 March 2020 (UTC)

Not merge. One is the paint. The other is the practice. --Tagishsimon (talk) 00:21, 25 March 2020 (UTC)
@Tagishsimon: I am asking because different Wikipedias point to one or the other. English Wikipedia, for instance, has a single article, Fingerpaint, to which "Fingerpainting" redirects. The English, German, and Swedish Wikipedias are linked to by Wikidata's "Fingerpaint", but the French and Chinese Wikipedias are linked to by Wikidata's "Fingerpainting". How can this be resolved so that the English Wikipedia article points to all of them? Would adding them to the redirect do it? —DocWatson42 (talk) 22:42, 25 March 2020 (UTC)
There's discussion, above, at of wikipedia articles covering multiple subjects (such as fingerpaint & ~ing), and so if there are articles which cover both then they perhaps should be linked to a new item with an instance of Wikipedia article covering multiple topics (Q21484471) and having has part (P527) pointing at the distinct wikidata items. Equally, and despite the article name, you might decide that as the body of the article is about the technique, it might be better linked to the finger-painting item; that item is linked to fingerpaint via uses (P2283). Neither solution is very attractive; meanwhile I don't think linking to a redirect works, but probably mainly on an IDontLikeIt sort of a basis. All that is clear is that the existing two items are distinct and should not be merged :) --Tagishsimon (talk) 23:16, 25 March 2020 (UTC)

Hi. V136-3.45 MW (Q71812982) is a wind turbine model which has multiple tower heights. The different tower heights are used based on the site conditions.

Notable pseudonyms

Currently we use bare strings for pseudonyms/pen-names etc. almost everywhere. pseudonym (P742) has a datatype of string, and the standard way of denoting their use is via a named as (P1810) qualifier (also as a bare string). However, sometimes the pseudonym itself also has a Wikidata item (e.g. Richard Bachman (Q3495759), Mary Westmacott (Q12326342)), largely due to one or more Wikipedias having separate items for them. Such a Wikidata item ends up being pretty close to being an orphan, though, as other items that would usually be expected to link to it (e.g. the books authored under that name) have to use the string form, e.g. "Richard Bachman", rather than the item. There have been a few discussions around this at WikiProject Books, but no strong consensus, and as this is a wider issue that applies to other areas as well, it was suggested to bring it up for wider discussion here. Do other fields/projects handle this sort of case differently? Is there a nicer way to create links in cases like this? --Oravrattas (talk) 05:10, 18 March 2020 (UTC)

Such the author statement on Rage (Q277260)? I'd be inclined to use a stated as (P1932) qualifier instead of pseudonym (P742), since most such cases won't have a separate item for the pseudonym. Or perhaps both, where available. Ghouston (talk) 05:59, 18 March 2020 (UTC)
stated as (P1932) introduces another complication here: my understanding is that named as (P1810) is more appropriate for these (based on, for example, an earlier discussion here, as well as being what's documented in the data model instructions for books). But either way, the question is more about the case where there is an existing Wikidata item for the pseudonym, and neither stated as (P1932) nor named as (P1810) lets us link those. --Oravrattas (talk) 18:27, 18 March 2020 (UTC)

By the way, how many cases of "notable pseudonyms" are they? Nomen ad hoc (talk) 07:06, 18 March 2020 (UTC).

Since this applies to pen names of authors as well as stage names of actors and musicians, there will be MANY, including Mark Twain, George Eliot, George Sand, Poor Richard, Richard Bachman, Prince, Frankie Valli, Lon Chaney, Puff Daddy, Ludacris, ... --EncycloPetey (talk) 15:02, 18 March 2020 (UTC)
On the music side there's also solo project and probably a few more like it. Moebeus (talk) 01:52, 25 March 2020 (UTC)
I had a quick scan of items using solo project (Q7558495) and most of the ones I looked at are again orphans, not linked from anywhere else. Of the ones that also obviously have a separate item for the person using that "stage name", all the albums etc I checked that were released as the 'solo project' seem to have a performer (P175) of the underlying person instead, and nothing to denote the name under which they were actually released. This seems wrong to me. When someone creates a separate persona to produce music or a book or whatever, it seems to me that Wikidata should generally prefer to credit that persona directly, with the underlying 'human' behind that then linked from the alter ego item. --Oravrattas (talk) 07:40, 26 March 2020 (UTC)
I agree with this, there might be an artistic (or even legal) reason for using different names and it seems wrong to second-guess that. We also have to remember using "stated as" as a qualifier for every single "performer" statement, which can be bit of a hassle and is basically not done at scale (and how would bots know?). But I have a feeling it's a slightly controversial position. Good ol' Richard D. James has notably been the subject of some back-and-forth on this. Moebeus (talk) 20:52, 26 March 2020 (UTC)

Wikipedia article covering multiple topics (Q21484471) ←→ ?

How to mention covered topics in Wikipedia article covering multiple topics (Q21484471)? For example we have Top Heatseekers (Q2303631) which consists of Heatseekers Albums (Q43152918) and Heatseekers Songs (Q88072620) charts so I have added them as statement is subject of (P805) at Top Heatseekers (Q2303631). Is this correct way? Now how to mention that Heatseekers Albums (Q43152918) is covered in Top Heatseekers (Q2303631)? Eurohunter (talk) 12:26, 20 March 2020 (UTC)

I know of two different ways:
At some point I'm thinking we may need a property for "more specific version of" (which might handle calorie (Q87260855) and related cases better), but that's a discussion for another day. —Scs (talk) 13:19, 20 March 2020 (UTC)
@Scs: Top Heatseekers (Q2303631) has part (P527) Heatseekers Albums (Q43152918) but I wouldn't say that Top Heatseekers (Q2303631) is a main subject (P921) of Heatseekers Albums (Q43152918) because Top Heatseekers (Q2303631) is just about Heatseekers Albums (Q43152918). Eurohunter (talk) 10:30, 21 March 2020 (UTC)
We need proprerty like "is part of other article", "partly included in other article", "is covered in other article", "other article which thread is mainly covered". Eurohunter (talk) 10:34, 21 March 2020 (UTC)
Presumably that wouldn't be a property as such. There's a good reason that the links to Wikipedia articles aren't normal properties. Items (and their properties) are primarily about notable things in the world, not about WMF project content. - Jmabel (talk) 17:18, 21 March 2020 (UTC)
To me the main question is, why does the "parent" entity -- the one that's a Wikipedia article covering multiple topics (Q21484471) -- exist in the first place? Does it even represent a meaningful concept?
I think we could maybe use a better way of handling some of these situations, but I'm not sure. Similar to the "calorie" situation, I'm also thinking of traditional but ambiguous units like "ounce", which today have multiple, incompatible, more-precise definitions like ounce (Q48013) and troy ounce (Q1323615) and fluid ounce (UK) (Q69878540).
But, bottom line, I'm not sure we have to worry too much about representing these issues "just right" -- and especially when the main reason for the ambiguous entity is that it matches an equally-ambiguous Wikipedia article somewhere. —Scs (talk) 01:55, 22 March 2020 (UTC)

Is there a help page somewhere for this kind of situation? If not, it may be prudent to set one up as a resource to reference when encountering such articles/items.

@Jmabel: Help:Modelling/Wikipedia and Wikimedia concepts#Compound_Wikipedia_pages says to use has part (P527), whereas @Liuxinyu970226 says not to, above and at Wikipedia article covering multiple topics. I recognize that Bonnie and Clyde (Q219937) is an entity unto itself, whereas JPEG (Q2195) is not an entity, but a conflation of distinct entities. In other words, I think that help section should be expanded. Daask (talk) 21:07, 26 March 2020 (UTC)
I wasn't pointing to Help:Modelling/Wikipedia and Wikimedia concepts#Compound_Wikipedia_pages so much for the has part (P527) as for the fact that different interwiki links may need to go to different items. It's legitimate to create an item for whatever has a Wikipedia article in any language -- our linking approach pretty much requires that -- but then we have to model the appropriate relation of that item to other items more or less independently of the various Wikipedias. If the Wikipedia article is a really baggy monster, that may be difficult (or impossible) to do perfectly. - Jmabel (talk) 23:53, 26 March 2020 (UTC)
I think in the JPEG case the notion of a conflation (Q14946528) is exactly right. If someone thinks that is worth adding to Help:Modelling/Wikipedia and Wikimedia concepts#Compound_Wikipedia_pages, feel free.

@Jmabel: Yes, I only said that has part (P527) is not suitable for Wikipedia article covering multiple topics (Q21484471), Bonnie and Clyde (Q219937) can use has part (P527), because it's a duo (Q10648343) entity, not just an item that is covering some randomly combined articles. --Liuxinyu970226 (talk) 00:05, 27 March 2020 (UTC)
PS: Ampang and Sri Petaling lines (Q474391) seems likely, two Malaysian railway lines that combined on nearly all Wikipedias, and hence none of users tried to split ever, but just added conflation (Q14946528) Wikipedia article covering multiple topics (Q21484471). If you think disallowing has part (P527) for Wikipedia article covering multiple topics (Q21484471) isn't fair then why Q474391 is fair :P? Still, I think that Help:Modelling subpage needs to modify. --Liuxinyu970226 (talk) 00:09, 27 March 2020 (UTC)
I know I'm repeating myself but: "I think in the JPEG case the notion of a conflation (Q14946528) is exactly right. If someone thinks that [using conflation (Q14946528) rather than has part (P527) to describe incoherent Wikipedias articles] is worth adding to Help:Modelling/Wikipedia and Wikimedia concepts#Compound_Wikipedia_pages, feel free.

Honest question: what are people doing with the COVID-19 data on Wikidata? Certainly there are more reliable, more credible, and more up-to-date sources. Hopefully no health care professionals are making critical decisions based on Wikidata completeness (or lack thereof): they rely on CDC, WHO, ECDC, and local health offices. It's great when data is reasonably complete, but Wikidata is and will always be a haphazard, hodge-podge, idiosyncratic database run by volunteers, with no guarantees on data quality or completeness. -Animalparty (talk) 20:56, 24 March 2020 (UTC)
Wikidata can allow the smaller Wikipedia's to provide COVID-19 data in lanugages that currently don't have good official sources. Given that unfortunately COVID-19 does spread in more developing countries now, that seems to be a valid use-case to help those populations to inform themselves.

Important for tool maintainers: last steps of wb_terms table migration

Hello all,

This is an important announcement for all the tool builders and maintainers who access Wikidata’s data by querying Labs database replicas directly.

In April 2019, the Wikidata development team started a heavy redesign of an important table of the database, wb_terms. Over years, this table has become too big, causing various issues. That’s why we decided to split it into several smaller tables. For more context, you can have a look at previous announcements: April 2019, May 2019.

We encountered a lot of unexpected issues on the road which required us to postpone the timeline, but the final steps of the migration are now happening. We published a blog post to explain more in detail what we did and why it was important to optimize the database structure.

Here’s an overview of what happened, what are the next steps and how you can update your code:

  • The new structure is now in place on Labs. You can read more details on this documentation page
  • Wikidata is entirely reading from and writing to the new tables since March 18th, which means the existing wb_terms table is not updated anymore
  • This means that any tools that are still reading from wb_terms and updating Wikidata based on its content have to be updated as soon as possible
  • In order to fully deprecate the table and make it clear that it is outdated, the wb_terms will be renamed to wb_terms_no_longer_updated on Monday, March 30th. Tools still querying this table at that date will certainly encounter errors.
  • To get an overview on how to update your queries, you can have a look at these examples

If you have questions or encounter any issues, please write on this Phabricator ticket or write me an email.

We apologize for the delay and the lack of recent updates regarding this change. Cheers, Lea Lacroix (WMDE) (talk) 15:56, 23 March 2020 (UTC)

@Lea Lacroix (WMDE): with your action to rename "wb_terms" to "wb_terms_no_longer_updated" you're actively breaking tools. That's not very nice at all. Please just truncate the table (empty all rows) and maybe create an empty "wb_terms_no_longer_updated". What phab task is this tracked in? You completely missed the announced timeline and you can't expect tool maintainers to jump up with just a week notice. Multichill (talk) 17:37, 24 March 2020 (UTC)
The wb_terms table is not updated anymore. This means that tools that keep reading data from it, and potentially editing Wikidata based on this outdated information, can cause some damage to Wikidata on the long run. This is why we need a clear change. Yes, this may break tools if people don't update the code. Our intention here is not to break tools but to strongly encourage people to stop reading from the outdated database.
In that regard, truncating the table will not achieve that. If people are fine with their tool reading wrong data, they can still change the table name in their code to be the new table name.
We are aware that this project took way longer than planned, and that the initial announcement didn't reflect the current timeline. However, this also let a lot of time for people to understand the new structure and adapt to it. The next steps that we can finally take are only the continuation of the project and the new structure didn't change since 2019.
We apologize for the 1 week notice. We chose this date in order to give some time to people to update their code while not letting this outdated table be used for too long. Lea Lacroix (WMDE) (talk) 10:58, 25 March 2020 (UTC)
@Lea Lacroix (WMDE): How can you read wrong data if the table is truncated?
By removing a table you make some database queries go down in flames and effectively completely disabling a tool.
From my point of view it looks like you don't really care about the tool maintainers, you didn't even bother to link the relevant phabricator task and you're planning to disrupt our tools and make it our problem.
@Lydia Pintscher (WMDE): as the product manager you're responsible for this. I would like to hear your response. Multichill (talk) 18:34, 25 March 2020 (UTC)
Hey everyone. I'm really sorry. I'm on vacation but now working with the team to see what we can do. Léa will get back to you in a bit. --Lydia Pintscher (WMDE) (talk) 09:00, 26 March 2020 (UTC)

Hello all,

We have been discussing with the team to come up with an additional solution to avoid a sudden break of tools.

Since March 18th, the wb_terms table is not updated anymore. We failed to announce this step of the process and we apologize for that. This step is unfortunately not reversible. This means that wb_terms contains data that is outdated and will be even more outdated every day. The up to date data is in place in the new structure.

In order to ease the transition, we are going to add a wb_terms_no_longer_updated table which contains all the wb_terms data from the point in time the updates stopped. This should happen in the next hours. On April 6th (previously announced March 30th), we will empty the wb_terms table. This is similar to the solution proposed by Multichill but preserving a version of the current table, in case people still want to use it.

This way, people maintaining tools that directly query the database will have three options:

  • Update their code to use the new structure
  • Update their code by renaming “wb_terms” in “wb_terms_no_longer_updated” (temporary solution, as it is an outdated and frozen version of the data)
  • Change nothing, starting on April 6th the tools will query the empty wb_terms, which will return no data, but that might be less drastic for the tool than having no table to query at all

What do you think about this solution? Would it be an OK compromise to facilitate the transition to the new structure?

About Phabricator tasks, see the ticket for the main overview of the project, more details about migration of items and properties, and examples of new queries.

We apologize for the troubles caused and we will investigate this issue to make sure that it doesn’t happen again in the future. Lea Lacroix (WMDE) (talk) 16:52, 26 March 2020 (UTC)

I understand that the change is a technical necessity, and I applaud the effort that went into it. But, why can there not be a view on the new structure that replicates wb_terms? Maybe even call it wb_terms, after moving the table to wb_terms_no_longer_updated? One of the reasons I did not change my code over until now is that before March 18, querying the new structure would have missed older labels etc., and I could not support both at the same time. A view, with a time limit of a few weeks, would give me and others time to migrate now that this is an actual option. --Magnus Manske (talk) 17:07, 26 March 2020 (UTC)
@Lea Lacroix (WMDE): Thanks for your reply Lea. That was the compromise I was looking for.
@Magnus Manske: Judging from this reply I think making a database view is technically not feasible. Multichill (talk) 17:24, 26 March 2020 (UTC)
We researched the possibility to create a view but the table is simply too big. Accessing the data would be way too slow. Lea Lacroix (WMDE) (talk) 17:53, 26 March 2020 (UTC)
Is wb_terms_no_longer_updated eventually to be removed in the future?--GZWDer (talk) 05:13, 27 March 2020 (UTC)
Yes, we don't want to leave an outdated table accessible for too long. But we should leave it long enough so people have time to update their code. We think one month is reasonable. Lea Lacroix (WMDE) (talk) 08:54, 27 March 2020 (UTC)

Unreliable and deprecated sources

Do we have a consensus 1. not to use some sources or 2. to remove some sources that is considered "unreliable" or "deprecated" by some projects (e.g. Daily Mail, NNDB)? Previous we have some discussion not to do that, but @Nikkimaria: does not think so. This user also removed some Find a Grave sources where there's consensus to keep (in this case there's more reliable sources present, So I have no opinion against removing them, but they may be readded by Reinheitsgebot).--GZWDer (talk) 09:50, 28 March 2020 (UTC)

  • I think it varies if they are generally unreliable, or just considered to be so by some project, for some purpose or by user Nikkimaria.
We had countless RFCs on the deletions of Nikkimaria, asked them not to delete them, and they still continue. Not sure if another RFC would really help. --- Jura 10:02, 28 March 2020 (UTC)
  • The whole point of deprecating claims is to keep the data but mark it as wrong. If anything this can help to show that sources are unreliable, whereas removing them just leaves the data open for re-addition. --SilentSpike (talk) 10:59, 28 March 2020 (UTC)
  • The data is still present, with better sourcing; in such a case there's no reason to keep worse sourcing. Nikkimaria (talk) 12:28, 28 March 2020 (UTC)
  • I think I have misunderstood, I thought this was about removing deprecated statements supported by unreliable sources, but it's just about removing "deprecated" sources. Haven't quite formed my opinion on this, I can see the argument for removing a source if a better is available, but also the logic in listing as many sources as exist. --SilentSpike (talk) 13:21, 28 March 2020 (UTC)

  • Looking at the type of statements that you do reference with it, it doesn't strike me as problematic. Nikkimaria would probably replace them with Britannica. Personally, I find Britannica problematic as it's a tertiary source, but I understand that this view isn't necessarily shared by them. Other references would be interesting. --- Jura 14:14, 28 March 2020 (UTC)

Need help for merging

I can't merge Q28150740 and Q5295136, can anyone help? I've deleted the Wikipedia links from the first entry and I've added them to the second entry yet the entries should be merged, I think. Thanks. —  Ark25  (talk) 18:34, 29 March 2020 (UTC)

They aren't the same thing. Laurell (Q28150740) is a family name item and Laurell (Q5295136) is a disambiguation page item. In particular, en:Laurell is a disambiguation page of given names and family names using Laurell, so can't be moved to Laurell (Q28150740). If the other language pages are specifically for Laurell as a family name then you can unlink them from the disambiguation item and relink them to the family name item. A merge is not appropriate. From Hill To Shore (talk) 19:15, 29 March 2020 (UTC)
@From Hill To Shore: You are right, thanks for the answer. The Swedish article sv:Laurell is for Laurell as a family name. Yet it should be changed into adding given names too. And then Laurell (Q28150740) can be deleted. —  Ark25  (talk) 21:33, 29 March 2020 (UTC)
@Ark25: Family name items shouldn't be deleted. They are a vital part of the structure for biographical entries. Both the disambiguation item and the family name item should be retained as separate items. From Hill To Shore (talk) 21:37, 29 March 2020 (UTC)
You need to use a different template at enwiki to indicate that it's a disambiguation page. --- Jura 21:41, 29 March 2020 (UTC)

can't add link to "en"

Hi there, on Alfa Romeo (Q622489) i would like to add the link to the article on the English Wikipedia which is "Alfa Romeo in Formula One" however, for some reason i can't add that link. What is happening here? Kind regards, Saschaporsche (talk) 18:28, 25 March 2020 (UTC)

This is because Wikidata requires items be dissected to their finest element, and broad concept encyclopedia articles like "history of X" or "X in Y" don't necessarily have 1-to-1 correlations with other language wiki articles covering the same topic. The English article is linked to Alfa Romeo in Formula One (Q65960697), which seems to be the most broadest scope (a subclass of Alfa Romeo in motorsport (Q173886)). Alfa Romeo (Q622489) refers to the Alfa Romero team(s), which compete in the events, but are not the events. -Animalparty (talk) 18:56, 25 March 2020 (UTC)
Q622489 is the current team, there are other items for previous Alfa Romeo teams in the 1950s (Q61467970) and 1970s-1980s (Q84562554), and as an engine manufacturer (Q31890903). Q65960697 combines all of these, but some links have been moved to Q622489 when the items were merged, possibly incorrectly. Peter James (talk) 00:02, 26 March 2020 (UTC) I looked at the content again, and they are duplicates - it was just the title that suggested they were not.

If you take a look at Alfa Romeo (Q622489) you can see that there is NO link to any article in English language. I still think that adding "Alfa Romeo in Formula One" to Q622489 is the correct solution. kind regards Saschaporsche (talk) 12:25, 26 March 2020 (UTC)

So I guess the English Wikipedia article already has an entry at Wikidata and it can't be merged with this entry Diviš (Q1231604) (which contains items for cs, de and ru languages).

And then, how can I find the Wikidata entry for the en:Diviš article? —  Ark25  (talk) 01:24, 30 March 2020 (UTC)

If you are viewing on a desktop computer, the Wikipedia article should show a link to the Wikidata item on the left hand panel. This should be present in all language versions of Wikipedia if the article has been linked (if you can't find the Wikidata link in the foreign language, just hover over each link until you see the one pointing to the Wikidata URL).
In this case, the English article is sitting correctly at Diviš (Q21502071) as it relates solely to family names. If the other articles are solely about family names they should be relinked to the family item. If they include other subjects in addition to family names they should remain linked to the more general disambiguation item. From Hill To Shore (talk) 07:48, 30 March 2020 (UTC)

Article “De rerun natura” (Q861986) of “enwiki” should be linked with the article “O přírodě” (Q15640251) of “cswiki”

The article “De rerum natura” (Q861986) of the “enwiki” doesn’t link to the Czech language version - article “O přírodě” (Q15640251) of the “cswiki”. I am obviously not allowed to save the link (I tried it to be sure and received an error).

I request that someone with appropriate access links the articles. 01:34, 30 March 2020 (UTC)

The article cs:O_přírodě seems to be about a translation, not the original work. In that case, the item O přírodě (Q15640251) can be made an edition item, similar to Della natura delle cose: libri sei (Q24577171). Ghouston (talk) 04:17, 30 March 2020 (UTC)

Wikidata objects for instances of Wikidata:Events? Out of scope or relevant?

I'm soon hosting an event. Regarding Wikidata:Notability it may qualify for "2." but I doubt it fulfills "The entity must be notable, in the sense that it can be described using serious and publicly available references.". Am I in the wrong for bringing this up or is this a topic of any value? Datariumrex (talk) 09:44, 30 March 2020 (UTC)

Merging entries about name disambiguations

Q16445474Bartuska (Q36935631)Bartuška (Q82014430) — They are all about the family name "Bartuška" (and it's variant "Bartuska"). Yet some of the Wikipedia articles were created as plain disambiguation pages (cs, de, lt) instead of being created as name disambiguation pages. That's why Wikidata has more than one entry for the same thing. These entries should be merged into a single entry and the other two should be deleted. And some people will argue they should not be merged - like for example here.

At this moment, it is actually harder to interwiki-link such articles between them, because of Wikidata. It was easier to link them in those times when Wikidata did not exist yet.

For sure, there are (tens of) thousands of situations like this - for example "Bareikis" and "Diviš". So I think someone should be in charge of solving such issues. —  Ark25  (talk) 03:46, 30 March 2020 (UTC)

Already solved, we distinguish items about disambiguation pages, given/family names and its variants (see Wikidata:WikiProject Names), although wikis often conflate these into one or more pages. No need to merge these.--Jklamo (talk) 11:12, 30 March 2020 (UTC)
Some languages use disambiguation templates on surname pages, then when the Wikidata items are created, disambiguation statements to them, usually by bots. If these are not disambiguation pages, the people who operate these bots need to know which wikis do this, and to stop adding disambiguation statements. Peter James (talk) 18:36, 30 March 2020 (UTC)

how bad are loops in the subclass-of hierarchy?

I think I've heard this mentioned somewhere, so it's probably no surprise, but I just had one of my little programs crash on what turned out to be a loop in the subclass of (P279) hierarchy:

Is this considered a problem, and is there any wish to / hope of fixing it? (In the meantime I'll fix my program; I'm not holding my breath. :-) ) —Scs (talk) 11:25, 30 March 2020 (UTC)

@Scs: I'm not sure, but there's also variable-order metaclass (Q23958852) which is (correctly, it seems) an instance of itself, so some loops are okay. Sam Wilson 12:44, 30 March 2020 (UTC)
A loop in the subclass of (P279) hierarchy is not *necessarily* an error, but such loops are almost invariably a symptom of a modelling problem. It can be difficult, however, to determine just what the fix should be. In this particular case, which of the above subclass of (P279) links are incorrect, if any? Or are they all correct, and the four concepts in question are actually the same (and should probably be merged). The english descriptions of the concepts are not very helpful here. Peter F. Patel-Schneider (talk) 12:47, 30 March 2020 (UTC)
matter (Q35758) says it has more than one definition; substance (Q27166344) appears to be an attempt to define an ambiguous term (two definitions of "substance" are the items with "substance" in the title, but there are more). Because of the ambiguity, either "substance" or "matter" may be a subclass of the other. The difference between material substance and matter is also unclear - matter can include antimatter. Peter James (talk) 13:17, 30 March 2020 (UTC)
Subclass loops are bad, but we do occasionally get them. I regularly monitor the problem cases shown on Wikidata:WikiProject Ontology/Problems but some are easier to clean up than others... Help is welcome! ArthurPSmith (talk) 14:40, 30 March 2020 (UTC)
If I understand the idea behind it, physical substance (Q28732711) is supposed to represent anything made out of fundamental particles, including the particles themselves (since massless particles travel at the speed of light and don't really form "substances".) So I've broken the loop by removing the relevant subclass statement from that item. Ghouston (talk) 22:54, 30 March 2020 (UTC)

Wikidata weekly summary #409

Could not save due to an error. The save has failed.

For wikidata:, I am getting the error: "Could not save due to an error. The save has failed", when trying to publish the Wikipedia item as en:David H. McConnell.

Please help!--Greghenderson2006 (talk) 17:40, 30 March 2020 (UTC)

@Greghenderson2006: Sorry about the bad error message. However, there already was a Wikidata item for this person - David H. McConnell (Q5234543) - which had that enwiki link. I've merged the two items now. You can find an existing Wikidata item for any Wikipedia page by looking at the left-hand navigation bar and clicking on the "Wikidata Item" link (under "Tools").

@Greghenderson2006: Done. Usually we merge into the item with the lower ID (which would have been the 3rd in this case) but since it had nothing linking to it internally I went ahead as you asked. See Help:Merge for how to be able to do this yourself... ArthurPSmith (talk) 20:16, 30 March 2020 (UTC)
And the external links? --- Jura 21:50, 30 March 2020 (UTC) not loading

I posted about this before, just wanted to update in case any others have been dealing with this as I've figured out the cause.

Since 2015 the BBFC have classed as an adult content website (see their re-review in 2018 here). This means in the UK it is blocked by ISP adult content filtering if your ISP is a mobile operator. For some reason my ISP had not started enforcing this until recently I guess (although I can still access clearly adult websites elsewhere). Anyway, if anyone else has the issue you should be able to disable the filtering somewhere. --SilentSpike (talk) 17:46, 30 March 2020 (UTC)

Data on Coronavirus > Wikidata > Wikitable in English

What might it take to automatically update the plot commons:File:CoViD-19 US.svg each time the data table in w:2020 coronavirus pandemic in the United States#CDC reported U.S. totals is updated?

I think a key part of this would be to translate fr:Modèle:Tableau qualificateurs; it seems currently not to be available in English. I could probably translate the documentation from French into English, but I don't have access to the code that actually does the work. I don't know what language that's written in, but I could probably find the French-language labels and translate those into English and make it all work with a little help. (I started writing Fortran in 1963. I've written code in many different languages since then and debugged code in languages I didn't really know.)

Updating commons:File:CoViD-19 US.svg automatically will take more than just this, but this is a big part of what would be needed to automate that. And, of course, this capability has many other applications in facilitating crowdsourcing all kinds of data collection and analysis, e.g., a v:International Conflict Observatory, which I believe could potentially facilitate a dramatic reduction in armed conflict worldwide.

COVID-19 confusion

The COVID-19 page here is pointing at a mixture of topics: some are descriptions ofthe disease but others are pointers to pages about the current pandemic. I am no expert on naming conventions but In my wiki-travels I met one enwiki wikipedian who has been doing nothing else for years. Wikidata should engage some experts like this here imio.

Best way to go about getting all "classes" that have atleast one {?thing wdt:P31/wdt:P279 ?class} relationship


I'm building an interface for performing simple SPARQL queries on Wikidata. I need an autocomplete feature for this, for which I've used the Wikidata query service thus far. However, I only want to list wikidata entries that have at least one entry that is an instance- or subclass of that first entry.

Should I download a dump and set up my own index? If this is possible to do using SPARQL or some other service, that would be greatly preferrable.  – The preceding unsigned comment was added by Matsjsk (talk • contribs) at 09:06, 25 March 2020‎ (UTC).

@Matsjsk: There are 69548 direct classes:
SELECT distinct ?class  WHERE {
  ?item wdt:P31 ?class.

Try it!

and 114965 superclasses:

SELECT distinct ?class  WHERE {
  ?item wdt:P279 ?class.

Try it!

I think these should cover all. Unfortunately combined query (P31/P279*) times out. --Infovarius (talk) 18:48, 31 March 2020 (UTC)
