Could anyone eliminate this. I rushed over and created an existing page for the same link. Conde Edmond Dantès (talk) 00:40, 1 August 2019 (UTC)

Elimination likely isn't the answer. It sounds to me like you created a dublicated item. In that case you have to merge both items that are about the same thing. ChristianKl❫ 11:12, 1 August 2019 (UTC)

Discussing a potential merge

I think the items comptroller (Q673633) and (Q12306661) should be merged. As far as I can tell, they are both about the occupation, called "comptroller" or "controller". Some of the links should arguably be in the item auditor (Q10949665) instead. The thing is, I'm not completely certain to what extent these concepts overlap in all of the different languages. Where should I bring this potential merge up for discussion? Gabbe (talk) 04:50, 1 August 2019 (UTC)

Hi!

edit check

I'm wondering what I did wrong to trigger a revert - see this If I'm messing up - let me know now before I continue too much further. Reverts usually signal something really wrong. TY for your time Ched (talk) 15:31, 5 August 2019 (UTC)

  • The field is called "description" so adding "description" in there isn't really helpful. Try to write a sentence "<heat lightening> <is (a)> <text from description>"
BTW, English labels and descriptions should usually start with lowercase letters. No period at the end. Help:Description might help.
"lightning not accompanied by thunder sound" might do. --- Jura 15:43, 5 August 2019 (UTC)

Would it be safe

to set the sex or gender (P21) for those 63700 items to male?

select ?item where {
  ?item wdt:P31 wd:Q5 .
  ?item wdt:P735 ?voornaam .
  ?voornaam wdt:P31 wd:Q12308941 .      
  optional {?item wdt:P21 ?geslacht} .
  filter (!bound(?geslacht))}

Try it!  – The preceding unsigned comment was added by Edoderoo (talk • contribs) at 19:25, 30 July 2019‎ (UTC).

It's possible that there would be some errors, since it's not unheard of for females to be given supposedly male given names, including in middle names, and vice versa (e.g., Willy Kanis (Q388542). There are also Wikidata oddities, such as "Marian" having different items for "male" and "female" versions: Marian (Q545486) and Marian (Q20155725). There's no guarantee that the right one will be used: Marian Hedwig Mülberger (Q55906557). Ghouston (talk) 04:09, 31 July 2019 (UTC)
I don't think that's a good idea. ChristianKl❫ 13:53, 31 July 2019 (UTC)
Imho it also sounds a bit risky. Given name may not unfrequently shifts gender accross countries or time period (or get mixed up with false friends) and I'm not certain Wikidata currently reflects all theses subtleties. Alexander Doria (talk) 13:59, 31 July 2019 (UTC)
Good example of this problem: Maria (Q25413386). - Jmabel (talk) 15:44, 31 July 2019 (UTC)
It sound more than "a bit" risky, I guess it would possible to cross this with other data to be sure it' actually men? For instance if it's a priest and with a male given name, then it's very likely a man (just to illustrate my point, it's not a very good example, there is only 8 priests in these results) Cdlt, VIGNERON (talk) 19:45, 31 July 2019 (UTC)
I actually see exactly the same issues if I fill in the gender by hand, so I should refrain by editing someones gender, until I had a chance to peek into their pants? Another question, why do we register gender, first of all, especially if it is so tricky to fill it in. Edoderoo (talk) 07:42, 1 August 2019 (UTC)
There can be references, typically where somebody is referred to with a gendered pronoun. Ghouston (talk) 09:15, 1 August 2019 (UTC)
Why would a gendered pronoun be more a more useful reference then the property on the wikidata item of the first name? Edoderoo (talk) 10:16, 1 August 2019 (UTC)
Because the gendered pronoun directly implies which gender the person has while first names are in many countries relatively unregulated and contain many expections. ChristianKl❫ 11:21, 1 August 2019 (UTC)
If you look more carefully to the SparQL, you will see that the gender is defined in the linked first name. For the names that have no specific gender, like Mischa (Q18229299) the query has no outcome. For firstnames that can be both male or female, like Marian, there are two wikidata-items. I assume that they are not randomly given to peoples wikidata-item. The above script should not set male to females, unless someone attached a male firstname to a female. Then the error is already there. Edoderoo (talk) 11:29, 1 August 2019 (UTC)
I've assumed that "male given name" just means the name is usually assigned to males, and there's nothing wrong with using that item for females too. Having two items for the same name would seem silly, because they are the same name after all. Ghouston (talk) 01:53, 2 August 2019 (UTC)
Personally I wouldn't name it silly, as it just depends how far do you want to specify a first name. You can easily defend that Maria, Marja, Mara and Marian have the same origin, and are therefor the same first name. About assumptions you are right. My assumption is that we can freely copy the assumed gender from the first name in case it is missing. When entering it manually, we do exactly the same thing after all. Edoderoo (talk) 08:17, 2 August 2019 (UTC)
Should we have male and female versions even of "unisex" names like Adrian (Q372250)? What would be the advantage? Every name is potentially unisex. I think a better idea would be to change the descriptions "male given name" or "female given name" to just "given name". I was momentarily confused by Adrian (Q372250) because the description in Dutch is "mannelijke voornaam", or "male forename", so I wondered if there was a female version, but there doesn't seem to be. In cases where there are two versions of a name, we also haven't considered which one to use for people of unknown sex or non-binary sex. Ghouston (talk) 08:52, 2 August 2019 (UTC)
@Edoderoo: We register gender because it's information that people care about. It allows automated scripts to find the right pronoun. It always people to answer questions such as "Which are the 5 biggest cities that are ruled by female majors" via SPARQL that are hard to answer without Wikidata. ChristianKl❫ 11:21, 1 August 2019 (UTC)
In Sweden we have the tradition that we add the name of the hamlet somebody comes from into the name. Then the name would still be female even if it is used on a male person. (Or the other way around.) IP (Hej!) 09:02, 2 August 2019 (UTC)

soweego 1.0 release

(Please disregard this message if you have already read it in the Wikidata mailing list, and apologies for the distraction)

  • TL;DR: soweego version 1 is out!
  • Like it? Star it!

Hi everyone,

The soweego team is delighted to announce the release of version 1! If you like it, why don't you click on the Star button?

soweego links Wikidata to large catalogs through machine learning. It partners with Mix'n'match, which mainly deals with small catalogs.

Soweego bot (talkcontribslogs) is currently uploading 255 k confident links to Wikidata: see it in action! 126 k medium-confident links are instead getting into Mix'n'match for curation: see the current catalogs [2], [3], [4], [5], [6], [7], [8], [9], [10].

The soweego team has also worked hard to address the following community requests:

  1. sync Wikidata to external catalogs & check them to spot inconsistencies in Wikidata;
  2. import new catalogs with reasonable effort.

Thinking of the best way to contribute? Try to import a new catalog.


Hjfocs (talk) 08:59, 31 July 2019 (UTC)

Have thought about this possible application of machine learning in the past, very cool stuff, will be keeping an eye on this! --SilentSpike (talk) 13:07, 31 July 2019 (UTC)
@Hjfocs: Just curious, could you please give a definition of „large catalogs“? What means that? A dataset with more than X records? --Succu (talk) 19:28, 31 July 2019 (UTC)
@SilentSpike: thanks for the kind words and the star on GitHub! Stay tuned for version 1.1 proposal: m:Grants:Project/Rapid/Hjfocs/soweego_1.1.
@Succu: thanks for the nice question. The order of magnitude is millions of records. For instance, the latest Internet Movie Database (Q37312) name dump (people) [11] contains 9.5 million entries roughly.
Cheers, Hjfocs (talk) 16:55, 2 August 2019 (UTC)

Moving statements from one property to another

Is there a way to easily move statements from quotation (P1683) to quotation or excerpt (P7081)? The former property should only be used in references to include supporting text from a quotation (and is apparently usable for qualifiers but I'm not sure if that's an appropriate use case), so it would be nice to have something similar to {{Autofix}} for those. Right now there are a few dozen constraint violations which would be resolved by changing to the newer property. Jc86035 (talk) 16:55, 29 July 2019 (UTC)

@Pasleim:.--GZWDer (talk) 17:00, 29 July 2019 (UTC)
Write mw.loader.load( '//ěj_Suchánek/moveClaim.js&action=raw&ctype=text/javascript', 'text/javascript' ); // [[User:Matěj Suchánek/moveClaim.js]] to Special:MyPage/common.js. Then reload the property page P1683, and you'll see move/copy buttons on each claim. —MisterSynergy (talk) 17:08, 29 July 2019 (UTC)
@MisterSynergy: I already had that installed. Did you copy the wrong JS? The script is only for copying statements between different items, not for changing the property while retaining the statements on the same item. Jc86035 (talk) 17:19, 29 July 2019 (UTC)
Oh I see, I misunderstood your request. You don't want to move claims between property pages, you want to move claims in items from one property to another. Yeah, that needs bot code, not a user script.
Fortunately, I have such code as well, adapted from Pasleim's version a while ago. If you describe your task in more detail, I can have a look whether I can help you. Pasleim seems to be quite busy offwiki these days. —MisterSynergy (talk) 17:52, 29 July 2019 (UTC)
@MisterSynergy: There are only 41 affected items, though I wouldn't really want to replace them all manually. The lexemes should probably be using usage example (P5831) instead, and I think most of the items should be using quotation or excerpt (P7081) (or the statements should be removed). As an example, on Article 1 of the Basic Law for the Federal Republic of Germany (Q712652), I would want the statements to essentially be unchanged except for the property number (the datatypes are the same). Jc86035 (talk) 16:00, 2 August 2019 (UTC)
Article 1 of the Basic Law for the Federal Republic of Germany (Q712652) is done per Special:Diff/991089102 (except for the copyright status (P6216) qualifier which is now being suggested). I just need QIDs to perform those moves, and it is fairly simple for me to do that. So if you sort that out, I'd do the moves. Lexemes are not supported by the move script anyways, thus you need to fix them manually. —MisterSynergy (talk) 19:07, 2 August 2019 (UTC)

────────────────────────────────────────────────────────────────────────────────────────────────────@MisterSynergy: Having checked all of the statements on items, it seems most of the statements are problematic in other ways, though I would still move most of them to quotation or excerpt (P7081). I think a more in-depth discussion about the acceptable uses of quotation-related properties (e.g. through proposing a property for quotations about things, or proposing to widen the scope of quotation or excerpt (P7081)) would be necessary to determine whether we should keep this data.

In summary, at most four of these would work without any constraint violations (if none of the P7081 constraints are changed). Jc86035 (talk) 17:22, 3 August 2019 (UTC)

I just moved statements in 12 items, as indicated above. Let me know if you need more moves… —MisterSynergy (talk) 18:11, 3 August 2019 (UTC)

I don't think this would be a valid use of YouTube video ID (P1651), since the statement would violate the property's type constraint. Jc86035 (talk) 05:25, 2 August 2019 (UTC)
I agree. That property is for copies on Youtube of the audiovisual work described in an item (films, trailers, music videos, etc.).

On a second thought after think about why one is linked from the other. One seems to be the action of recording, the other seems to be the result of that action. If so, we should update the description to be more clear. --D-Kuru (talk) 09:46, 2 August 2019 (UTC)

Ineligible for copyright

There are a number of items representing concepts which could form and/or be described as creative works, but are nevertheless not copyrightable due to not being complex enough (e.g. C diminished seventh (Q58233626)). The Commons analogues are c:Template:PD-ineligible and c:Template:PD-shape. Is there an item which can be used as a determination method (P459) qualifier for copyright status (P6216) statements, or does one need to be created? Jc86035 (talk) 17:29, 3 August 2019 (UTC)

Common needs these templates to mark files, which could (in theory) be copyrighted, hence the need for the template. I don't think there is a need for something like that here. Circeus (talk) 20:35, 3 August 2019 (UTC)
Your example can be marked up like this; which is factually correct, but perhaps does not serve any useful purpose. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 08:58, 4 August 2019 (UTC)

same label and description

I can't understand why we can't have two items with the same label and description. Georgios Papadopoulos (Q53996986) Georgios Papadopoulos (Q66108465) Xaris333 (talk) 20:01, 3 August 2019 (UTC)

because the description are supposed to be disambiguating and if they are not, they're no more useful than there being no description at all? Circeus (talk) 20:40, 3 August 2019 (UTC)
The other reason, I think, is that if there are two items with the same label and description, it is quite likely that they're duplicates. So the prohibition is a nice reminder to double-check for that -- and if indeed they're not duplicates, the requirement to make the description distinct (to get past the prohibition) also serves to make the description more specific and more useful as a discriminator. —Scs (talk) 13:52, 4 August 2019 (UTC)

Movement Strategy online surveys - opportunity to share your thoughts about reworking movement structures

Community conversations are an integral part of movement strategy “Wikimedia 2030”. They have been ongoing in multiple formats and in numerous languages over the last 2.5 years. Now it is possible to also contribute to the development of recommendations on structural change via an online survey. We are keeping the survey open for additional 2 weeks and post it to wikis to provide wider opportunities to participate for people interested in it.

The survey is available in 8 languages: Arabic, English, French, German, Hindi, Portuguese, Simplified Chinese, and Spanish. They contain designated questions about each of the nine thematic areas that the working groups are analyzing and drafting recommendations for.

Wikidata items for references/citations?

Can Wikidata be used to store references for Wikipedia? I mean, today a Wikipedia article uses a book as reference. My question is can we make an item on Wikidata for the book and then use the Wikidata item as a reference in an article? Like this, references could be tracked easily, being shared among multiple articles etc.--Kozuch (talk) 11:26, 4 August 2019 (UTC)

PS: In Wikimedia_Foundation_Annual_Plan/2018-2019/Final I can see following: "High quality citations support verifiability. To build a more reliable internet based in facts, we need a more robust network of references on and beyond Wikipedia." This may point to using Wikidata for citations.--Kozuch (talk) 11:30, 4 August 2019 (UTC)

  • Wikidata stores most of the fields needed for w:Template:Citation. I think there is some development ongoing to store it more systematically (cite extension?).
Also, Wikidata stores references for specific statements that can be displayed on Wikipedia (e.g. date of birth). Not that this is really new. --- Jura 11:43, 4 August 2019 (UTC)

That is a very interesting topic that you have brought up and will most likely be a hot topic for Wikidata in the time yet to come. I think that Wikidata Bridge will be the project to really make this change come alive, and connect Wikidata and Wikipedia like Wikipedia and Commons are linked today. If you are looking for an existing way of using Wikidata entries with w:Template:Citation. Will I recommend using w:Template:Wikidata. - Premeditated (talk) 13:25, 4 August 2019 (UTC)

  • I don't quite see the relation, but w:Template:Cite Q might be closer to what Kozuch has in mind. --- Jura 13:33, 4 August 2019 (UTC)
    Cite Q documentation has the following warning at the beginning:
Warning: From the TfD closure: "[...] works-in-progress should rarely be used in the article space until they are 99% finished/accurate/etc. Until the matter of transcluding Wikidata on Wikipedia is resolved (most likely with a huge and contentious RFC) usage of this template should be extremely vetted to ensure that all of the transcluded information is accurate."
 – The preceding unsigned comment was added by Jc3s5h (talk • contribs).
  • Well that's just enwiki and it's not even red there. Other Wikipedias might not require their volunteers to re-copy references for each statement. --- Jura 17:38, 4 August 2019 (UTC)
  • Pictogram voting comment.svg Comment When you talk about making a Wikidata item for a book, you need to be careful, because a book (in Wikidata terms) should never be cited. A "book" can mean a particular work, or a particular edition of that work, or a particular physical copy of that edition. For that reason Wikiproject:Books has rejected the use of book (Q571). Instead you should cite an edition of a book. In other words, you need one data item for the work and another data item for the edition (specific year, specific publisher, specific ISBN, etc.), and you should cite that edition of the work. Different editions will have different publication details, possibly different page numbers, and even different text, so it is important to cite the particular edition used as a source. --EncycloPetey (talk) 21:03, 4 August 2019 (UTC)

Checking if a concept exist in Wikidata

Wisselstraat Brussel Zuid.jpg

In Dutch there is the railway term 'wisselstraat' for a combination of Double slips (Q14905968) crossing diagonaly the other tracks. In de Commons:Category:Railway points in Belgium there are many examples of this. Is there a Wikidata item for this? It is a combination of Q14905968. In Dutch there is only a redirect nl:Wisselstraat (spoorweg) is 'wisselstraat' kan also be a ordinary streetname. ('straat' is 'street' in English) As in Wisselstraat (Q29939452).Smiley.toerist (talk) 12:47, 31 July 2019 (UTC)

@Smiley.toerist: If you're referring to the concept of multiple double slips one after the other (as in the photo), I don't think this concept exists in most languages so it's probably safe to assume that a Wikidata item doesn't exist. If there isn't an existing sitelink then I probably wouldn't create an item for it, although I guess you could create a lexeme for "
" and then link a new item for the concept to the lexeme. Jc86035 (talk) 16:09, 2 August 2019 (UTC)
I am thinking of using 'multiple double slips lane' for a Commons category. This is then a start. Can later be added to Wikidata.Smiley.toerist (talk) 14:00, 5 August 2019 (UTC)

"Error in Wikidata"

Can someone point me to or perhaps explain how to fix issues arising from "Error in Wikidata". In particular at Ovis aries. DonSpencer1 (talk) 03:41, 5 August 2019 (UTC)

I think the problem is that the VN template used by the Commons gallery is intended to be linked with a species item on Wikidata, but the gallery has been linked with a common name item instead. It should be linked with Ovis aries (Q29350771), not sheep (Q7368). Ghouston (talk) 06:45, 5 August 2019 (UTC)

Wikidata weekly summary #376

dedicated to / named after / titular

Hello! As you may know, churches, chapels and altars are named after a saint or another religious figure (God, Trinity), which is called "titular [saint]"; for example, the titular of a "Saint Paul church" is saint Paul. As far as I know, currently there are two properties used for it, property:P825 ("dedicated to") and property:P138 ("named after"); both are somehow correct, but a new "titular" property would be far more appropriate. Is it possible to create it? --Syrio posso aiutare? 12:02, 5 August 2019 (UTC)

Also commemorates (P547). What issue would another property address? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:37, 5 August 2019 (UTC)

Modeling the Survey of Scottish Witchcraft database on Wikidata - which property proposals to go forward with

Hi, currently have a property proposal in place for 'manner of torture/punishment' in place but looking at other interesting data in the Survey of Scottish witchcraft database and looking at where there maybe a good case to argue for inclusion on Wikidata and a new property proposal:

  • Date of torture (add as qualifier to manner of torture/punishment using Point in Time?)
  • Date of confession
  • Location of confession
  • Date of arrest
  • marital status - assume we would just link to spouses, children, siblings, relatives using those existing properties? However, this is sparse.
  • accused of - there is rich information in terms of the different things the accused witches are actually accused of e.g. devil's mark, shapechanging (to a cat, a dog, a hare, an apparition).
  • Ordeal type - technically distinct from the extrajudicial torture that took place although many ordeals involved painful procedures, this was a test conducted in order to let nature or God reveal the truth. Values would include: Bierricht (corpse bleeds), Ducking (otherwise known as the water test, Pricking (the body of the suspect witch was pricked with pins in order to find a Devil’s mark). I imagine we could characterise under manner of torture/punishment if having a separate property for ordeal proved inappropriate. Although this test would have formed part of the trial process.
  • Ordeal date.
  • Cause of malice - why the accused witches were accused of acting as they did (values such as revenge, debt, slander, grudge, failed business). Could Has Cause (P828) be used here? It is more of an accusation/complaint than a direct cause though.

Any thoughts on how these could work? Stinglehammer (talk) 11:15, 23 July 2019 (UTC)

@Stinglehammer: Try to use as much as possible significant event (P793):this reduces the need of specialized properties.
Ex: significant event (P793):confession (Q1219996)
point in time (P585):XX.XX.XXXX
Or significant event (P793):arrest (Q1403016)
point in time (P585):XX.XX.XXXX
location (P276):Y
Snipre (talk) 22:30, 23 July 2019 (UTC)
@Stinglehammer: There is the property convicted of (P1399) too. Snipre (talk) 06:48, 24 July 2019 (UTC)
Many thanks Snipre, this is very useful and a good workaround which encompasses much of what we're looking to achieve. We had planned on using significant event (P793) to link the accused witch to the item on their witch trial. I would just question how useful it is to have confession, arrest, trial and more all under the significant event (P793) umbrella from a modelling and querying point of view. If the general consensus is this is best practice then can certainly import with that method in mind. Any thoughts on the other property types I mentioned? Stinglehammer (talk) 11:45, 24 July 2019 (UTC)
I think an "accused of" property could be valuable and even extend easily to modern persons/companies (where subject item of this property (P1629) is accused (Q28056401)). The "cause of malice" should probably be specified as a qualifier of some sort, but I'm unsure what's best. I think all of the "date of" and "location of" can be done using significant event (P793). --SilentSpike (talk) 08:45, 29 July 2019 (UTC)
Can definitely look to put forward a property proposal for accused of if this would be useful elsewhere too. We've been working with adding date and location information via the significant event (P793) property as suggested above for confessions etc. One thing to note is that we have items of data for each instance of Scottish witch trial with trial dates now added. However the database also includes case dates whereby the case denotes the whole period of investigation the accused witch is subjected to so it could cover a ten year period with one or more or multiple instances of witch trials in this period. Therefore we were wondering whether significant event (P793) could be used again with a new item created for witchcraft investigation/investigated for witchcraft and then dates added as qualifiers. OR whether we might need to create a new item for EACH case and then have those link to the trials.e.g. Case of Isobel Gowdie. Thoughts on this would be welcome. Stinglehammer (talk) 14:58, 31 July 2019 (UTC)

Since so many of these properties involve dates, I should interject that I have emailed Prof. Julian Goodare, one of the editors of the database. The dates in the database use the calendar that was in effect at the time and place of the event described, which is nearly always the Julian calendar, since England and Scotland didn't convert to Gregorian until 14 September 1752. Also, Scotland considered the year to begin on 25 March until 1600, and England did the same until 1752, but the database always treats 1 January as the first day of the year. So dates from the database should be mapped to proleptic Julian calendar (Q1985786), not proleptic Gregorian calendar (Q1985727). Jc3s5h (talk) 14:04, 2 August 2019 (UTC)

Many thanks Jc3s5h, Prof Julian Goodare is aware of the project and meeting with us next week to discuss the work to date with a view to quality assuring. The dates seem to have defaulted to Gregorian on import so we are making changes accordingly. We now have items of data for (1) accused witches in the database (biographical, geographical data added) and these are linked to (2) the witch trials they underwent and (3) the people associated with those witch trials (sherriffs, lairds, judges etc.). Returning to my other question, we also have dates of 'cases' which are defined as "The witchcraft case follows the series of events and specific accusations that emerged from a denunciation of a person accused for witchcraft that was pursued by either ecclesiastical and/or civil authorities. The case encompasses the beginning (i.e. initial denunciation or supposed denunciation), middle (i.e. the investigation, arrest and trial of an accused witch), and end (i.e. the way the case ended in dropped charges, a verdict of innocence, or execution) of a witchcraft accusation. The ‘case’ does not only refer to a trial or trial process but also includes references to cultural beliefs about witchcraft practice that were found in the documents. It should also be pointed out that ‘case’ refers to one individual who was accused of witchcraft. The term does not refer to a series of trials in a large witch-hunt." e.g. .e.g. Case of Isobel Gowdie - would it be appropriate to have this modelled as significant event (P793) and linked to a newly created item for 'investigated for witchcraft which would be an instance of inquiry (Q21004260) and/or a subclass of witch hunt (Q188494) as a way of including the dates of the case/period of investigation? We have case dates for almost all 3,219 accused witches but trial dates for only 600 so modelling case dates would be very useful for querying/visualising purposes. Thoughts welcome on this.

New data type for EntitySchemas

Hello all,

Based on community request, a new data type is about to be created, in order to link to Schemas from statements. You can already have a look at it on Beta (a test property has been created). The value type is string, so you will enter for example "E1" as a value.

You can learn more in the ticket. This data type will be available on August 7th. Cheers, Lea Lacroix (WMDE) (talk) 15:01, 5 August 2019 (UTC)

Thanks, but why string? Wouldn't it have been wiser to make them entities just as items, properties, and lexemes?
  • One could search for EntitySchemas by label, instead of having to type the E-ID.
  • Use in WDQS would have been more comfortable.
  • It would create backlinks.
    • That would make it easier to validate all statements with this data type via the pagelinks table at any time. Now the value is apparently validated during input (i.e. needs to start with "E" and then followed by numbers; E-ID needs to exist). However, if the EntitySchema is deleted or merged, it will be difficult to update this in statements.
    • Even more in general if everything goes smoothly, it would be interesting to easily find items which link to an EntitySchema.
--MisterSynergy (talk) 15:40, 5 August 2019 (UTC)
@MisterSynergy: With this datatype, it should be possible to unlock Wikidata:Property proposal/Shape Expression for class, that in turn will allow us to write human (Q5) : Shape Expression for class = E10
Presumably this will then add a line wd:Q5 wdt:Pxxx wd:E10 to WDQS (though @Lea Lacroix (WMDE): it would be good to confirm that this will indeed be the case).
You're right that, regarding backlinks, there does appear to be a problem -- eg shows nothing, whereas it ought to show as linking there. Jheald (talk) 19:05, 5 August 2019 (UTC)
In WDQS it will look like wd:Q5 wdt:Pxxx 'E10'. Those are strings, not IRIs, pretty much as with Commons category (P373). —MisterSynergy (talk) 19:15, 5 August 2019 (UTC)
Well that would just be a complete pain. I have added comment phab:T214884#5394245 to the Phabricator thread, that the datatype is not ready to go if this is what would be the case.
EntitySchema-valued properties ought to work in exactly the same way as Lexeme-valued properties, as per eg this query: Jheald (talk) 19:32, 5 August 2019 (UTC)

Hello all,

Thanks for your quick feedback. It seems that we have indeed more things to discuss and to investigate here, in order to find more sustainable solutions. I don't have a precise date but since part of the team will be busy with Wikimania, it will be postponed at least to the end of August. Lea Lacroix (WMDE) (talk) 07:36, 6 August 2019 (UTC)

Thanks, glad to read this. Some additional thoughts: if you make EntitySchemas entities rather than string, ...
  • ... they would come with a canonical URI (which we don't have yet, but ShEx validation needs this as well to reliably resolve relative URIs to absolute ones); see phab:T225778
  • ... their labels etc. could be incorporated in WDQS
  • ... the actual ShEx code could be linked in WDQS as well, e.g. wd:E10 foo:shex <> (with foo:shex being some quickly invented placeholder here, as I am not sure which predicate one would really want to use). We do something similar with images which are not by themselves in WDQS, but there are links to image files at Commons via wdt:P18

New gadget: related items

Wikidata is a strongly interlinked database with many items having ingoing and outgoing links. Unfortunately, the user interface does not display any ingoing links ('inverse properties'). For example, it does not display which notable people are or were member of Footlights (Q857679).

I've created a gadget which enhances the user interface by exactly this kind of information. You can activate it under Special:Preferences#mw-prefsection-gadgets by setting a tick at relateditems. This will add you a new button to the bottom of each item with which you can load the incoming links.

The scope of service can be expanded by any user. Just add to a property page with item datatype a new statement inverse label item (P7087) linking the property to an item containg the inverse labels. --Pasleim (talk) 19:05, 5 August 2019 (UTC)

@Pasleim: Thanks for turning this into a gadget. Does this work with statements on properties (or lexemes, etc.)? I tried to use this on inverse label item of (Q66205187) (which is, of course, now used in a inverse label item (P7087) statement on inverse label item (P7087)) and the inverse statement doesn't show up. Jc86035 (talk) 10:58, 6 August 2019 (UTC)
The gadget only works on item pages but it shows incoming links from items and properties. So if you go to anthem of (Q65933124) the gadget will show you inverse label item of (Q66205187)=anthem (P85). --Pasleim (talk) 15:49, 6 August 2019 (UTC)

Cleaning up the class tree of « Wiktionary linguistic edition »

It seems the superclass tree of Wiktionary language edition (Q22001389)  View with Reasonator View with SQID is really wrong. Can someone help cleaning this up ?

A linguistic edition of Wiktionary should never became … an industry according to Wikidata, for example. A linguistic edition should not became an instance of Wiktionary, as wiktionary is a concrete project and an instance of a project should not become an instance of another one. It should be a part of the bigger project, not an instance of it.

This could be used in the "Search Wikidata" field, and also in the edition dialogs, such as when selecting an item for instance of (P31).

Why is this important? Because people sometimes select the wrong item, generating much confusion.

    • Having it at both places would be valuable. Later one when statements can be created from Wikipedia that search interface likely should likely also have it. Item search as well as property search should have it. I'm not certain about lexemes. ChristianKl❫ 18:54, 7 August 2019 (UTC)

I solved this by replacing a «subclass of» unit of analysis with an « instance of » claim.

I readded omnivore (Q164509) to regain the link to organism (Q7239) however this may have (arguably) introduced some additional noise. The reason for this seems to be that component (Q1310239) is a conflation between an "abstract piece of something" and a "type of manufactured good (Q22811462)". I'm not sure how the latter is intended to be used but maybe deep down we're all just type of manufactured good (Q22811462)s and I'm just too prideful to admit it. :P --- ElanHR (talk) 05:08, 8 August 2019 (UTC)

Company Name imports from GRID

Hi Wikidata folks. At the moment, I believe Wikidata downloads the entire company name from the GRID Database for entities, e.g., which may cause some confusion with international brands, institutes, etc. and also multiply entries unnecessarily, e.g. and Is there some way to exclude parenthetical information from the pulled GRID Company Name for future entity references, and does anyone have any ideas about fixing the multiples problem for existing content? Thank you.  – The preceding unsigned comment was added by (talk • contribs).

Thanks for bringing this to our attention. It appears that these two items were created by different means, and only the former comes (directly) from GRID. This question might be better addressed to the maintainer of @APSbot, @ArthurPSmith. Bovlb (talk) 00:27, 9 August 2019 (UTC)
It looks like it's been merged now. I'll look at leaving out the parenthetical country components of GRID names in the future - it's also a good idea to be a little more careful when creating new entities to match existing things - a simple search in the UI would have found the old entry in this case for example.

taxon name (P225) and taxon rank (P105) usage in instances of organisms known by a particular common name (Q55983715)

Entities using the taxon rank (P105) property should be instances of taxon (Q16521) (or of a subclass of it), but pig (Q787) currently isn't.

I got the warning above when I added taxon name (P225) and taxon rank (P105) properties in an item that is an instance of "organisms known by a particular common name (Q55983715)"

In my opinion, the warning should not be displayed for instances of organisms known by a particular common name (Q55983715), because it is possible for a group of organism to be in the same taxon rank as in this example (pig - genus Sus), or dog, or cat, etc. Bennylin (talk) 05:43, 7 August 2019 (UTC)

Multi-language default editor for labels

Hi, I have some technical question

Right now when I'm viewing items, the default language is shown in two row, Indonesian (my default language), and English (I guess site default? I never set it manually). But now what should I do to add more languages in the default label editor (for example Javanese - jv). I tried to change my preference -> editing -> translation option, from "en" to "en, jv", but it still doesn't show it for me. Any help would be appreciated. Thanks.

Name of Wikidata properties in a dynamic Infobox

Do we need more labels for Wikidata properties when presenting it in a different context like Infoboxes? can we use the name property name (P2561) or name of issued by (P2378) ?

  • when we are in edit mode in Wikidata we would like to see a label telling "Find A Grave memorial ID"
  • when presenting external identifiers in a dynamic infobox we maybe should have another label "Find a grave:"'

Examples of "Infoboxes" displaying all labels

  • Wikidocumentary George Washington see Facts
  • user Larske did a test Template in sv:Wikipedia playing around see link
    • we tested using different labels (Larske correct me if I am wrong)

@Susannaanas, André Costa (WMSE), Larske: - Salgo60 (talk) 10:48, 10 August 2019 (UTC)

@Salgo60: The test function "auktoritetsdatatest1" can now be called with an optional parameter shortnames. shortnames=ja gives the result that the short name (P1813), if it exists, of the external identifier is used as (link) text in the box. See the sandbox. Note than only a few external identifiers do have a short name (P1813) defined, se this list, but you can try to add some more short names for identifiers with very long labels. It can be a challenge to define a short name (P1813) that is short but still unique and possible to understand. --Larske (talk) 08:26, 11 August 2019 (UTC)

OT: regarding the "show all template in sv:Wikipedia" I right now feel a Wikidocumentary solution maybe is step 1 (ex. en,sv) and if other people think "show all" is the way forward we can have a new discussion in sv:Wikipedia what to do.

P180 on abstract or diagrammatic images

How would one use depicts (P180) to describe something like an abstract drawing or a simple geometric shape? I've been thinking about using structured data for the BSicon (Q21152830) image set on Commons, and this would probably be an issue; the individual images are often almost meaningless on their own, but may represent specific things and can be used to draw complicated diagrams.

@Rich Farmbrough: You can link to redirects, but it's necessary to blank the page first (or otherwise remove the redirection). After linking you can restore the redirect.
Also, if the two concepts are very similar to the point that the different sitelinks mostly cover the same topics, you can use Template:Interwiki extra (Q21286810) to add the correct interwikis to the respective articles without having to modify any redirects.

It costs energy as a community when people don't accept the consensus of the RfC's we have and try to fight the decisions. ChristianKl❫ 15:58, 13 August 2019 (UTC)
As seen in the subsequent discussion, the RFC didn't authorize the protection of all items Abian protected, but apparently Abian didn't accept that, didn't unprotected items protected in violation of protection policy nor attempt to make steps to implement the RFC in a reasonable way. So users like me end up having to deal with the fall out. --- Jura 16:05, 13 August 2019 (UTC)
Abian seem to think that all of those 3000 most used items have >500 references. Are you saying that you know that some of those don't have that many references? ChristianKl❫ 16:50, 13 August 2019 (UTC)

New proposed data model: Post-conviction relief

I'd like to propose a new data model, but I can't find a relevant WikiProject through which to propose it. It would include a bunch of new properties. This is an extension of my proposal to add an "exonerated of" property. The purpose of this proposal is to better represent the complexity of legal systems, especially the ways in which a person may be found to be innocent (exoneration) or less culpable (commutation) after an initial conviction. (If there's a better place to start this conversation, please let me know.)

Data Model for "Post-Conviction Relief"

What is it: the category of legal actions taken after someone is convicted of a crime that can lead to reduced or eliminated sentences. This model covers pardons, exonerations, and commutations. In general, I propose that these be represented by pairs of properties -- one would be a "post-conviction relief applied" qualifier to the "convicted of" property, and the other would be a standalone property in its own right ("exonerated of", "pardoned of", "received commutation for")

New qualifier

Convicted of: <crime>

  • Point in time
  • Etc…
  • NEW: Post-conviction relief applied: <pardon|exoneration|commutation>  -- constraint: must have corresponding property, e.g.: exonerated of

New properties

-Kenirwin (talk) 20:03, 12 August 2019 (UTC)

The model here is that you normally are commuted after 2/3 of the time. You have to do something extra ordinary to do full time. IP (Hej!) 07:34, 13 August 2019 (UTC)

Discussing Inclusion criteria for lists like television series episode (Q21191270)

For well known series like Star Trek episode (Q61220733), the included episodes on Wikidata is quite exhaustive. (700+ items) Similarly for The Simpsons (Q886) where it has about 600+ items.

But for a smaller show like Suits (Q370185), even when at least some episodes are on some language wikipedia, there are no records found.

I think for the sake of consistency, it makes most sense that to modify the inclusion criterion to something along the lines of

That creates completeness, rather than half data for series that are not quite as popular but still popular enough to warrant some Wikidata entries. And I believe on Wikidata we should strive towards complete data as much as possible

Soni (talk) 20:41, 7 August 2019 (UTC)

Where is this inclusion criteria that you would have amended? Wikidata:Notability/Inclusion criteria is not it. Can't find it within Wikidata:WikiProject Movies. Nor is it covered AFAICS at Wikidata:Notability; but that page makes the point that items are notable if they meet some structural need, which episodes of a series surely do. As to the proposed change: should is inappropriate for an inclusion criteria, in the sense that the criteria for item A should not be 'oh go on then, create also items B - Z'. Could is appropriate for an inclusion criteria, but the structural need notability criteria seems to have that angle covered already? --Tagishsimon (talk) 21:00, 7 August 2019 (UTC)
  • If not all episodes of "Suits" are here it's just that nobody bothered including them. --- Jura 21:04, 7 August 2019 (UTC)
  • With the current standards there's nothing stopping someone from creating items for all episodes of Suits. We don't need to change any policy for this case. There might be cases where a YouTube user has a "TV series" with 1000 episodes and one of those episodes is a source for a Wikidata claim. In a case like that I woulnd't want a policy statement that says we automatically should add items for all the episodes. ChristianKl❫ 07:12, 8 August 2019 (UTC)
    • This. Nothing is witholding you to document every episode of a notable television series. Just takes some time. Sjoerd de Bruin (talk) 09:07, 8 August 2019 (UTC)
      • Thank you all for this clarification. I did not know if documenting every episode was a good idea or not, and did not want to waste time doing so, only to be deleted. Hence thought it's better to clarify policy/ask directly for the policy to be changed before I start doing so. Soni (talk) 19:12, 13 August 2019 (UTC)

Looking to create a dataset for our website

Our site appears in Wikidata, but I believe that there isn't an actual dataset for our movies/tv-shows on your website.

The idea is to export all the URLs from our website with a small description, so links will appear at the bottom of each movie/tv-show in relations to data that appears on our end and link the two.

I've seen it a couple of times in film/tv series items in the past few days, where at least IMDb ID (P345) and Netflix ID (P1874) would show such constraint violations, claiming that the value was also already used on a property (where the property number = the Q number of the item) as well as on the item itself.

Preferred status for population

@Martin Urbanec: is about to remove preferred status from the population property ([19]). He explained his reason here. I would rather see a preferred rank bank in this property. Is it the right way to record the population that way? Many features rely on the preferred status. Now you can see the strange effect in the infoboxes here: voy:de:Heilbronn and here: commons:Category:Heilbronn. If somebody wants to look for the most recent entry he can run through the result set of getAllStatements without being interferred by a possible prefferred rank, right? And besides, the bot PreferentialBot will put the rank back, if I understand it right. -- DerFussi 05:13, 9 August 2019 (UTC)

It is a result of a discussion on cswiki (w:cs:Wikipedie:Pod_lípou_(technika)#Počet_obyvatel_z_Wikidat), as for some municipalities 30+ years old data were marked as preferred. Removal of preferred rank for most recent data seems to be error in script to me. Anyway, PreferentialBot will fix all soon. Not limiting P1082 output is more likely design flaw of the template.--Jklamo (talk) 08:57, 9 August 2019 (UTC)
Maybe the edit summary should explain that (after an onwiki discussion). It's a feature (or known problem) that PreferentialBot doesn't adjust preferred ranks once new data is added. You'd have to ask @Laboramus: explicitly to do it. --- Jura 16:35, 9 August 2019 (UTC)

Query and infoboxes generally expect just one or a few values. Usually there are just 1 or a few values with preferred rank. Unless this is fixed by next Tuesday, I will undo the changes by Martin. --- Jura 12:24, 11 August 2019 (UTC)
Jura already answered. I agree, it's our local design flaw, that we are dependent only on a preferred rank not on a fresh date mark. Because of that infoboxes rendering whole list of population values or throw template argument size error. I notified our lua guys about it, but for this time they did not solve a problem.

Names in different alphabets

Some of European people has their articles in Japanese or Thai version of Wikipedia saved in their alphabets (names and pseudonyms). Are they transliterated or transcripted?

Can only speak for Thai, there names are usually transcribed, but using mai than tha khaat (Q4466856) to keep spelling close to original one. But IMHO, we should keep birth name and similar properties to those in the original script of the subject, only for a bi-national both scripts might be worth adding.

RfC about model for document description

Dear all,

I started a RfC to improve our model for document description. As I am not all-knowing, I did a proposition of model and I expect some modifications before we can launch a decision phase. The principle of that 2 phases RfC is to avoid to start the decision before having input from a large number of contributors mentioning particular cases which can change the original proposition. This is always frustrating to give its opinion about a proposition which changes several times between the start and the end of the decision phase.

“Wikidata item” link to be moved in the menu column on Wikimedia projects

Hello all,

Currently and since the Wikimedia projects pages and Wikidata items have been connected, the link "Wikidata item" appears on the menu column of the Wikimedia wikis, in the section "Tools".

However, many editors from various projects told us that it would make more sense to have the link in the "In other projects" section, since Wikidata is one of the Wikimedia projects and the Wikidata item link doesn’t really belong to the list of special pages.

This is why we are going to change the position of the link, on August 22nd for all Wikipedias and August 21st for all the other projects. After this date, you will find the "Wikidata item" link in the "In other projects" section.

In some cases, for example on help and meta pages, the section may contain two links to Wikidata, for example on en:Help:Contents where there will be the "Wikidata" link (linking to d:Help:Contents) and the "Wikidata item" link (linking to d:Q914807).

If you want to know more about the previous discussions or mention a bug or an issue, please add a comment to the related Phabricator task.

Thanks for your understanding, Lea Lacroix (WMDE) (talk) 09:45, 8 August 2019 (UTC)

  • The solution of having a "Wikidata" and a "Wikidata item" link in cases were seems to me like a good solution to the problem. I think it's helpful to list is in the list that way to introduce us as being a proper site in the Wikimedia ecosystem. I can't see of a reason why it would make the enwiki people mad, so I'm in favor. It feels to me that if there are no objections coming up here the time till the 21st is enough time so that further delay isn't needed if the hotkey still works.

Should I recognise original CAPITALICS from source or nOt? Eurohunter (talk) 09:55, 4 August 2019 (UTC)

  • What are "CAPITALICS"? Capital letters? Italics? Specifically capitals in italics? Something else? Is it a word always written entirely in uppercase? - Jmabel (talk) 16:13, 4 August 2019 (UTC)
    • @Jmabel: Yes just capital letters (schould be included or not). "Is it a word always written entirely in uppercase" - no there is no reason for it but capital letters are used sometimes in the titles of articles or for marketing purposes and question is if we should recognise it (original records) or not. Eurohunter (talk) 20:33, 9 August 2019 (UTC)
      • To my knowledge there is no definite rule regarding capitalization. I personally prefer to "normalize" all-capital letter strings to a more readable form, and it depends on the language what this exactly means. Mind that quite often names are only *displayed* with capitals only, but not stored in that form in the source. —MisterSynergy (talk) 20:40, 9 August 2019 (UTC)
        • @MisterSynergy: How to know how they are stored? What if capital letters are needed in some cases to destinglish one name from another and not in the others in one item? Eurohunter (talk) 17:53, 15 August 2019 (UTC)
          • You know how they are stored if you get them from a web page that is using an HTML small caps style via font-variant (or a now-deprecated tag), but the underlying content uses lowercase or mixed case. - Jmabel (talk) 23:40, 15 August 2019 (UTC)
            • @Eurohunter: I think that P1810 is not used "to destinglish one name from another". It's not a search string, but information about the subject. My interpretion is that the format is free, as already mentioned, but the intention for this property is to be accurate rather than to align with Wikipedia naming standards. If a list is in all caps I would probably normalize it, but if particular names are stylized, such as "A$AP Rocky", I would keep that format in P1810. The main use is probably not to show formatting, but to indicate where he's known as "Rakim" or some other "alias".

Biggest missing feature

I mentioned it few times already but it's the most important missing and basic feature of Wikidata. There need to be option to set up languages to edit labels and desriptions in languages which you want instaed of using babel template.

What are you trying to do? What's wrong with clicking on "All entered languages" for your use-case? Why do you feel it's impossible to use the babel template? ChristianKl❫ 11:08, 10 August 2019 (UTC)
@ChristianKl: I think Eurohunter's use case is specifically that he adds labels in all (or most) Latin-script languages at the same time, since this is possible/appropriate for items for which the label doesn't need to be translated. Using "All entered languages" doesn't work for items where this is necessary, since there has to be data for a language to be included in that list (if not indicated in the user's Babel boxes). Jc86035 (talk) 11:18, 10 August 2019 (UTC)

@Jc86035 : This is a habit I've had since is I first started editing, it's more or less on autopilot.

Help with given names and surnames

  • Maytê = given name
  • Bernardes = mother surname (1)

  • There is also second family name in Spanish name (P1950), if applicable, although I don't know how different Portuguese and Spanish naming customs are. -Animalparty (talk) 04:45, 13 August 2019 (UTC)
    • In Spanish custom, the mother's family name always comes after the father's, though, which seems not to be the case here. - Jmabel (talk) 06:14, 13 August 2019 (UTC)
Portuguese naming is opposite of Spanish: given name/mother's lname/father's lname (Spanish is given name/father's lname/mother's lname). So while Spanish people might omit the second last name, the Portuguese will typically omit the first last name. Scandinavian middle names are typically the same as the Portuguese "mother's last name".. 🤷‍♂️ Moebeus (talk) 23:33, 14 August 2019 (UTC)
So it sounds more like Scandinavian middle family name (P6978) than second family name in Spanish name (P1950); either the latter should be renamed (in English) to not be specific to Scandinavia, or we should have another property just like Scandinavian middle family name (P6978) for Portuguese usage. - Jmabel (talk) 23:44, 15 August 2019 (UTC)

What to do when two items share the same identifier

Hello, I was wondering what should be done when two items share the same identifier (with the property having a distinct value constraint)? This relates to UEFA player ID (P2276) as part of UEFA's player database. UEFA currently have a mistake with the following people who have the same name:

I would think both items should have the identifier. Is there a way this can be marked so the statements are not listed as having an 'issue'? Otherwise the identifier will continue to be removed from either one of the items. Thanks, S.A. Julio (talk) 05:19, 15 August 2019 (UTC)

When I'm looking at the list I'm not sure that a single value constraint is appropriate. It seems to me that Ermin Bičakčić (Q75993) has two values by virtue of being in the tournament both in 2016 and 2020 and that looks like it's intentional. ChristianKl❫ 11:27, 15 August 2019 (UTC)
@ChristianKl: I don't think it is intentional, UEFA use the same player ID for people in their match reports throughout their careers, except in these few instances. With the Ermin Bičakčić (Q75993) example, you can see the top bar of UEFA's website appears a bit different in the two links. This is because UEFA keeps a "cache" of player profiles to display. Occasionally the UEFA ID of a player will be changed, as in this case. While both links appear to be valid, the reason is a bit clearer looking at UEFA's competition database: the ID 250025190 is now invalid, and has been replaced by 250008197. However, because UEFA keeps this "cache" page, the profile of the invalid ID still is accessible on their site. S.A. Julio (talk) 23:06, 15 August 2019 (UTC)

Source item showcase

Lately I've been working to adequately source some of my statements because Wikidata as a whole is pretty lacking in that regard. However, there are a few hurdles I've encountered in the creation of source items which I'm only just now starting to understand.

I think to help others like myself and even just as a reference for the more experienced, it could be very valuable to establish some showcase source items (à la Wikidata:Showcase_items). Ideally, an item for each imaginable type of source (i.e. a book with multiple edition items; a periodical with multiple volume, issue and even article items; an e-book; an audio book, etc.) and an example of their use as a source. Perhaps it's best to create a separate area for this purpose for discoverability and since there's a slightly different priority to the item showcase.

Would anyone else be interested in something like this? We could set up a WikiProject and establish some goals. Admittedly I still have a few questions regarding source items, but part of the motivation here is to have those answered with future reference available. --SilentSpike (talk) 13:59, 15 August 2019 (UTC)

        • Yeah that is a good example of a book source item because it shows the correct work + edition structure with multiple editions. Basically I'd like to have some discover-able resource of different types of source items and their use that people can refer to if they need to create new such items to add as sources to statements. See the question I link to in my original post for an example of a situation where I have been unable to identify the correct source structuring in practise --SilentSpike (talk) 21:13, 15 August 2019 (UTC)

  • Symbol oppose vote.svg Oppose I would prefer to improve Help:sources first before starting to spread the information over several pages. People don't have the time to read to read several pages to find the information they are looking for and for me showcases can't provide a rule: there are always plenty of special cases and a showcase can't provide a good overview of what is important to respect. Snipre (talk) 20:04, 15 August 2019 (UTC)
    • I agree, especially when it comes to Help:Sources/Items not needing sources. --Succu (talk) 20:27, 15 August 2019 (UTC)
    • You raise a good point and updating the help pages could also be a priority for a WikiProject in this vein. I personally find it easy to learn from examples which is why I think it's valuable to have items for reference somewhere too (no need to do only one or the other). If we create a WikiProject we could even just use that as the repository of example items and include a link to the project from the help pages with the suggestion that sourcing questions be directed there. Any questions that do come up can be clarified on the help page and we can make sure an example is present that covers the situation (like testing in a development environment, you encounter an issue, you write a test for it so that future instances are caught). --SilentSpike (talk) 21:13, 15 August 2019 (UTC)
      @SilentSpike: The definition of a data model is often an iterative process with improvement of the initial model with the study of special cases which can't be covered by the inital formulation of the model. And this is why showcase can't be a good way to represent all particular details requiring additional properties/qualifiers. Often showcases represents the simple case in an item category (perhaps 80% of all items) and then to cover the remaining 20%, you need 2-4 additional showcases. So at the end you don't have 1 showcase by category but 3-5 showcases. And without any explanation describing what are the differences between the showcases: people have to analyze the difference shocases to understand what is the characteristics of each item and then establish themselves the general rule leading to the different models.
      Finally, do we really need a new Wikiproject for that ? Currently, when people have problem with describing sources they use the talk's page of Help:Sources. From my experience of Wikiproject, very few persons are involved in Wikiproject and it is difficult for someone from outside WD to find the correct Wikiproject where to present the problem. Most problems are solved directly in the Project Chat but then we lose the solution when the discussion is archived.
      My recommandation is to use Help:Sources as place for discussion and data model presentation. Snipre (talk) 21:54, 15 August 2019 (UTC)

Work in progress : a gadget to visualize class trees and subclass-of paths between two classes

Motivation : there is often problems with parent classes of some items − see for example the section #How a human becomes faultly an artificial entity above. It’s then useful to visualise the superclasses of a class to see which other classes their instances are also instances of.

So I created a gadget that allows to embed the graph visualisation of WDQS in a Wikidata item page. If a weird superclass is found


The few next steps :

  • add translations in other languages
    ✓ Done translation possible, translated if french 15:07, 16 August 2019 (UTC)
  • add a feature, for items who are instances of some class, to show to the user some of the other class he his instance of to spot some weird stuff, to help finding bugs in the class tree. For example if « Albert Einstein is an Abstract object » is shown this should raise suspicions. Maybe add a button to leave a message with the oddity on some page for other people to try to correct the bug.
    ✓ Done 15:07, 16 August 2019 (UTC)
    also ✓ Done, the ability to report a « bug » in the class tree, if it occurs something weird, such as human becoming an instance of law or something like that. 15:14, 16 August 2019 (UTC)
  • TODO: Other idea : show the metaclass (for example if an item is an instance of a class that is itself an instance of « car model », show that its class is a car model. 15:07, 16 August 2019 (UTC)
  • See if there is other ideas/suggestions/bugs after this post :)

Making progresses

I made progresses and implemented something for showing the classes an item is an instance of on a sandbox for this gadget User:TomT0m/classification/sandbox.js. It’s now possible to report weird instances to WikiProject Ontology by clicking a link of the gadget, resulting in [22] this kind of messages. (the weirdness comes from the fact that this item is labelled « heterotroph » in english and in french it’s more like « heterotrophia », which is a process)

Researcher and scientific articles

Trygve Ottersen (Q66424846) is a researcher and have published notable work (P800) A Typology of Scientific Advisory Committees (Q56797691) as author (P50) and other works as contributor to the creative work or subject (P767). Is it wanted that all (about 40 ) Works and "co-Works" shall be listed as notable work (P800) for this person? Pmt (talk) 19:18, 15 August 2019 (UTC)

No IMHO; only the notable ones. Nomen ad hoc (talk) 19:45, 15 August 2019 (UTC).

@Nomen ad hoc:, @Succu: and @ElanHR:. I do think the same as you they should not be listed for the researcher, and have had an answer. @ElanHR: Mainly such scientific articles do not have author (P50) , only author name string (P2093) so there is no "connection" to Trygve Ottersen (Q66424846) as author (P50) just author name string (P2093) as Trygve Ottersen. @Nomen ad hoc: You are reverting my edit by asking me, to what extent exactly it is notable? together With your comment No IMHO, only the notable ones. I can only answer to what extent exactly it is NOT notable? Being a scientific article, published in a well known scientific Magazine. Probably evaluated by other fellows. Recogniced for a publication by a Publishing commity. The main thing is shall all the scientific articles be listed as notable work (P800) for a researcher. Probably not. But there must be a better argument for not listen the article than just some dull not notable and at the same time the articles must be connected or related to the Author in some way. And I can not see that author name string (P2093) will cover this as long as it is a text string. The same for short name (P1813). Queries may be ok, but for daily use thay may be to "Heavy" I am just asking Pmt (talk) 23:57, 15 August 2019 (UTC)
Hi. I've replaced all claims of Ottersen as author name string (P2093) by author (P50) ones. Pmt, just publish a work in a well-know journal doesn't make it notable; it should have been cited ("evaluated by other fellows", in your words) a certain number of times, for instance, or, say, have received an award. So the burden of the proof of its "notability" lies with you. For me, the better solution to your concerns is, for each author, to replace all claims of P2093 by P50, as done in this case. Cheers, Nomen ad hoc (talk) 07:12, 16 August 2019 (UTC).
@Nomen ad hoc: Thank you for your answer. And thanks for changing from author name string (P2093) to author (P50). Is there any tool for doing this or is it done manually?

Hello. Why there is a constraint in Building of Ministry of Foreign Affairs (Cyprus) (Q66488884)? The statement is an example of a administrative territorial entity (Q56061). Xaris333 (talk) 04:00, 17 August 2019 (UTC)

Building of Ministry of Foreign Affairs (Cyprus) (Q66488884) has located in the administrative territorial entity (P131) of Ayioi Omoloyites, Nicosia (Q16868998) which was a instance of (P31) of Parish of Nicosia Municipality (Q47320699), which was a instance of (P31) of third-level administrative country subdivision (Q13221722) rather than a subclass of (P279) of third-level administrative country subdivision (Q13221722). I've changed this now. (See Teester (talk) 16:04, 17 August 2019 (UTC)

List of ministers.

Hello. Should I add all the ministers in Ministry of Foreign Affairs (Cyprus) (Q3315347) using chairperson (P488) (like United States Department of State (Q789915)) or should I add them to Cypriot Minister of Foreign Affairs (Q25309937) with officeholder (P1308)? (Of course with qualifiers start time (P580) and end time (P582) for both cases). Xaris333 (talk) 04:32, 17 August 2019 (UTC)

Well, a minister isn't a "chairperson" of its ministry, is it? So I would consider the second option. Nomen ad hoc (talk) 06:52, 17 August 2019 (UTC).

Qualifiers for identifiers

Which qualifiers should be included in identifiers? Schould they be inluded in references or schould they have references independly anyway (expect cases reference is needed to confirm that certain id is official)? Eurohunter (talk) 17:56, 15 August 2019 (UTC)

Qualifiers are usually used to differenciate several values, and as identifier are by principle unique, no qualifier should be used with identifier. Snipre (talk) 21:59, 15 August 2019 (UTC)
There are some exceptions to that rule, identifier shared with comes to mind? Moebeus (talk)
@Snipre: Shouldn't it have atleast named as (P1810) (any expections?) or identifier shared with (P4070) in few cases (very rare I think)? Eurohunter (talk) 23:29, 15 August 2019 (UTC)
I don't think there are any that should, but there are plenty that can. Some examples:
Perry Barr (Q7169723) has a good example of how qualifiers on an identifier can be appropriate - it uses subject has role (P2868) to clarify that it refers specifically to a certain type of administrative area, and has start/end dates because the admin area only existed in that period. Start/end dates can also be used where you have two identifiers that apply at different times (say an official ID scheme changed and they issued new ones for every item, or the external source breaks things down more granularly than we do).
named as (P1810) means that you can say what name the identifier uses, which might be very useful if, say, you have an author who writes under two different pseudonyms, and there are identifiers for each of them separately. Andrew Gray (talk) 19:57, 16 August 2019 (UTC)
@Andrew Gray: When I'm adding stated in (P248) as qualifier it shows me "The source property should not be used in this location (as a qualifier). The only one valid for this property is as the source". Eurohunter (talk) 21:07, 16 August 2019 (UTC)
I think this is because that particular property should only be used in references - it doesn't matter if it's for a normal property or an identifier. Andrew Gray (talk) 21:33, 16 August 2019 (UTC)
@Andrew Gray: Most of identifiers can't have references because it would be nonsense and would conflict with "real references" under identifiers that requires it. So what to do? Eurohunter (talk) 08:55, 17 August 2019 (UTC)
@Eurohunter: I'm not quite sure what you're trying to do here - is there a more appropriate qualifier you could use than stated in (P248)? If it's only for references, and you aren't using references, it's probably not the right one. Andrew Gray (talk) 09:28, 17 August 2019 (UTC)
@Andrew Gray: So why is bot adding it to references if it's not real reference? Eurohunter (talk) 10:54, 17 August 2019 (UTC)
I don't understand what you're asking. Could you show me an example? Andrew Gray (talk) 13:05, 17 August 2019 (UTC)
@Andrew Gray: [23] in reverse. Eurohunter (talk) 13:24, 17 August 2019 (UTC)
@Eurohunter: The problem here is that stated in (P248) should only be used as a reference, not as a qualifier. So the bot moves it into the references section whenever it's added as a qualifier. In this case, though, I don't think it makes sense to add as a qualifier or as a reference - what is it you were trying to say by adding this qualifier? Andrew Gray (talk) 16:46, 17 August 2019 (UTC)
@Andrew Gray: So what is the way to describe "id provider"? Eurohunter (talk) 19:04, 17 August 2019 (UTC)
@Eurohunter: In this case, I don't think we need to. "VIAF ID provided by VIAF" doesn't seem like something we need to state at all? But if we were saying "this ID was found in a different database", then a reference with stated in (P248) would be sensible. Andrew Gray (talk) 09:39, 18 August 2019 (UTC)

Participation in an event

If a person is set as a participant in an event entry I do not see that the event shows up as participated in from the person entry. I would think that logically the relationship should be established between the two records, but I am new to Wikidata. So for now, I should assume I always have to create a participant property in both the person and event records?

Thanks for any guidance...  – The preceding unsigned comment was added by Tdefarlo (talk • contribs).

IMHO participant in (P1344) in the participant's item would suffice.

I woukd say no for two reasons.

(2) This property should be qualified with start time, end time, replaces, replaced by - you can’t qualify a qualifier. That said, this seems to be a widely misused property. Values like “professor” and “2001” are incorrect. Perhaps the definition needs to be refined. And we need to add a lot of additional named professorships. - PKM (talk) 19:57, 16 August 2019 (UTC)

I recently added an image into an item (You Shook Me (Q1088200)). I saw two infoboxes of the Russian article ru:You Shook Me having the same image, but the infoboxes have different info. One is about Muddy Waters version; other the Led Zeppelin version. The Led Zeppelin image shouldn't have displayed a different release, so what can be done about it?

Hello George! Thank You for Your message. I fixed it in Russian Wikipedia, is it all right now? --Ksc~ruwiki (talk) 18:31, 17 August 2019 (UTC)
I see the edit now. Thanks, Ksc~ruwiki! Nonetheless, I would appreciate a hidden note like this: <!-- example -->. That way, most editors can understand why the edit is to be made. George Ho (talk) 18:54, 17 August 2019 (UTC)
That's a solution used only in Russian Wikipedia (I am not sure about other Wikipedias). The mechanism described here (in Russian: "Чтобы отключить свойство Викиданных, ничего не добавляя взамен, используйте в статье значение -. " --Ksc~ruwiki (talk) 19:27, 17 August 2019 (UTC)
  • In plwiki the word no (Q1814990) is used as argument for image file name to disable the image in those infoboxes, which uses some image property from Wikidata such as image (P18). Paweł Ziemian (talk) 17:44, 20 August 2019 (UTC)

Obtain a label onwiki in a specific language

I simply want, for example, the French label for sand (Q34679) to be returned. (sable) If there is no French label, I want nothing. Reading w:en:Module:Wd, my impression is that this is not possible without changing that module to return what I want instead of the language of the wiki. (and I don't speak Lua, so that's that) How do I do this? Alexis Jazz please ping me if you reply 23:40, 18 August 2019 (UTC)

@Alexis Jazz: {{#invoke:WikidataIB|getLabel|Q34679|lang=fr}} should do what you want - except the version of Module:WikidataIB here is a bit out of date, so you have to use it on enwp/commons/elsewhere with the latest version available. Thanks. Mike Peel (talk) 06:50, 19 August 2019 (UTC)
@Mike Peel: Thanks! I need it on Dutch Wiktionary, so I'll just import any required modules and templates. Alexis Jazz please ping me if you reply 08:33, 19 August 2019 (UTC)
@Mike Peel: The same thing doesn't work for descriptions, is that correct? They keep falling back to English. I needed this for wikt:nl:Sjabloon:vertalingen#Voorbeelden. Alexis Jazz please ping me if you reply 07:38, 20 August 2019 (UTC)
I think this needs @RexxS: to add lang as a parameter for the getDescription function. Thanks. Mike Peel (talk) 09:52, 20 August 2019 (UTC)
@Alexis Jazz, Mike Peel: It's not quite that simple, Mike. If you want the description in a particular language, you have to load the entire Wikidata entry, then look through the description table to find that language. Rather than have to import all of a modified WikidataIB and its dependencies into the Dutch Wiktionary, I've simply created nl:wikt:Module:Wdnl with the two requested functions. On its talk page, nl:wikt:Module talk:Wdnl, I've make some tests as a demo of how to call the functions and to show that they work in the way that I think was intended. if that doesn't do the job, then please let me know and I'll try again for you. Cheers --RexxS (talk) 16:09, 20 August 2019 (UTC)
@RexxS: Ah, sorry, I thought it would be straightforward. Is that because there's no description version of mw.wikibase.getLabelByLang? Thanks. Mike Peel (talk) 20:47, 20 August 2019 (UTC)
@Mike Peel: Principally that, but also determining whether the fallback languages are used or not. If I add the language parameter to WikidataIB|getDescription (which I can do), what do I do when someone else wants to be able to specify the language and have it fallback if that language has no description (which is how I treat getValue returns that are monolingual text)? I have all the code, so I suppose I could add a parameter |fallback=true or false for the call, and then the same for the labels. But it looks like work, so I think I'll wait for somebody to ask for the features. --RexxS (talk) 21:32, 20 August 2019 (UTC)

Change interwiki in VK (Q116933)

Hello, I'm kinda new to Wikidata, so, sorry if I'm asking in the wrong place. Can anyone edit the pt.wikipedia link in VK (Q116933)? The page has been moved from "VK (rede social)" to "VK" (proof). That means the item is linking to a redirect instead of the actual article. I can't do it myself because the item is protected. Thank you. GhostP. (talk) 22:51, 20 August 2019 (UTC)

Close to me: view Wikidata items on a map

Hey everyone, i made a new tool that lets you see Wikidata items with a location based on your current location. It's basically a wrapper around the 'map' view on the query service, but without the need to write a complex SPARQL query ;) Check out Close to me. Husky (talk) 08:37, 19 August 2019 (UTC)

Wow! Very interesting. Thanks! Nomen ad hoc (talk) 08:40, 19 August 2019 (UTC).
Honestly, there should be a well-maintained app that would have one's phone buzz anytime one is next to any of those spots and that would then have one take a picture that would immediately be uploaded to Commons and added as a relevant image (P18) here. Using the built-in clock and calendar of the phone (and possibly image recognition technology) could bring that app to use nighttime view (P3451) or winter view (P5252) instead. Thierry Caro (talk) 09:38, 19 August 2019 (UTC)

There's also the Commons app, which also shows the nearby Wikidata items. But not so smart - it includes items which are no longer existing, e.g. around my home it shows elements of the city wall torn down more than 100 years ago. My suggestion of filtering items with dissolved, abolished or demolished (P576) hasn't made it into the app yet... Ahoerstemeier (talk) 08:25, 20 August 2019 (UTC)
It's too bad the Commons app doesn't work on iOS :(. I could imagine showing items that have dissolved, abolished or demolished (P576) might be interesting as well, a picture of the place where those city walls used to be might of use to an article as well...

New termbox on mobile is now live

Screenshot of the mobile view of the termbox (taken from the Earth item on beta)

Hello all,

For the last few months, the Wikidata team has been working on improving the termbox interface on mobile. The termbox is this area on Items where you can read or edit labels, descriptions and aliases in various languages. Our goal is to provide a nicer experience while reading and editing this area from the mobile web pages.

Thanks to the combined work of various teams at WMDE and WMF, to our UX researchers and the editors who gave feedback on the prototypes, the first version of the feature is now deployed on

What is included in this new termbox interface?
  • You can browse labels, descriptions and aliases on a new and more mobile-friendly interface, for all existing languages
  • You can edit existing labels, descriptions and aliases directly from the interface of the Item
  • The behaviour of the mobile termbox is very similar to the current termbox on desktop: preferred languages are sorted based on the Universal Language Selector extension, that is taking information from your Babel userbox (if you’re logged in)
  • The edits made through the interface will have the “mobile edit” tag, so you can track them and watch out for vandalism
What is not included yet, but may be in the future?
  • A dedicated termbox-mobile tag in the edit summary, to track edits more precisely
  • Adding labels, descriptions or aliases in languages that don’t contain anything for now (we’re working on it, in the meantime, you can do it with Special:SetLabelDescriptionAliases)
  • Various interface enhancements (floating buttons, colors, icons, text labels)
What was not included in the scope of this project
  • Ability to edit something else than the Item termbox (eg. statements, Lexemes, other entity types)
  • Any change on the desktop interface

How can you test it and give feedback?

The feature is now live on, which means you can access any Item from a mobile device and check it out. You can also see it from desktop by clicking on the "mobile view" link at the very bottom of a page, or adding &mobileaction=toggle_view_mobile at the end of the URL. Example: Q666

Please note that some pages are cached - if you don’t see the new termbox appearing on an Item, it will appear next time that someone edits this item.

If you have any suggestions or would like to share feedback with us, you can write on the talk page of the termbox project.

If you encounter any bug or serious technical issues, you can also create a task on Phabricator, using the tag Wikidata-Termbox.

Cheers, Lea Lacroix (WMDE) (talk) 09:50, 21 August 2019 (UTC)

Edit: the newly deployed feature seems to have created some errors on Special:NewItem on mobile. We're working on this and the issue should be fixed in the next 24 hours. Sorry for the inconvenience. Lea Lacroix (WMDE) (talk) 16:58, 21 August 2019 (UTC)

Modelling the wiktionary …

The wiktionary class tree is a mess. I think that this is partly because the item is actually merging different meaning : the community, the dictionary itself, the mediawiki website … I propose to sort that out by creating an item for the wiktionary as intellectual work (Q15621286)  View with Reasonator View with SQID and the wiktionary project as a Wikimedia project (Q14827288)  View with Reasonator View with SQID. I also created an item for the website wiktionary website (Q66542603)  View with Reasonator View with SQID. Some wikipedia defines the wiktionary as a dictionary, some other as the project, which make the current item a little blurry however.

There is relationships between all those items of course, I can think of

  • ⟨ wiktionary (content) ⟩ produced by (P2849) View with SQID ⟨ wiktionary (project) ⟩
  • ⟨ wiktionary (website) ⟩ maintained by (P126) View with SQID ⟨ wikimedia ⟩
  • ⟨ wiktionary (website) ⟩ edited though search ⟨ wiktionary (website) ⟩

… (I don’t know if we have properties for everything)

The advantages are that the work item can clearly be subtyped as a kind of dictionary, and which, while the wiki itself is classified as a wiki … author  TomT0m / talk page 10:11, 18 August 2019 (UTC)

Symbol support vote.svg Support This sounds like a reasonable proposal to me. I see this kind of issue a lot where editors have combined multiple distinct concepts onto the same item. --SilentSpike (talk) 12:17, 18 August 2019 (UTC)
  • It's unclear what it's going to fix and if isn't going to make a mess of every other WMF site entry. --- Jura 17:58, 20 August 2019 (UTC)
    • @Jura1: We usually differenciate the work of some author and the authors itself, the editor, and we also discriminate editions of some work. Comparatively … why should we merge such different concept as a work, a community of authors, in the same items, for a few projects ? author  TomT0m / talk page 08:21, 21 August 2019 (UTC)
  • Lots of things are like this. The United States is an area, an organization, a set of people, a set of laws, etc. Splitting things up like that doesn't help. Wiktionary is a community, a dictionary, a website, and a project. --Yair rand (talk) 07:53, 21 August 2019 (UTC)
I think it's worth considering that all the wikimedia project items should be modelled the same way. Although there is a Wikipedia community (Q876040) (and there should reasonably be equivalents for the other projects), there is no separation between wikipedia as content as wikipedia as a website. They are, by and large, one and the same, and edited not through any purported "wikimedia website", but rather through MediaWiki (Q83). Anyway, before you start unleashing this on other items, how about you start with wikipedia items, and remember that there is not so much a wiktionary website (Q66542603) as there are language editions (i.e. English Wiktionary (Q22001375)).

Is there a property to indicate that an item or URL is the draft version or manuscript of the item to which the property would be attached? Arlo Barnes (talk) 18:54, 21 August 2019 (UTC)

Is Q55900412 the same as Q18202241

We have items for Hermann Buttersack (Q55900412) and Hermann Butterweck (Q18202241), two German actors with the same name, born the same month and died on the same day. They have different VIAF, GND and CERL IDs, but I suspect that they are the same person who had 2 entries in GND which were duplicated in VIAF and here. I am not sure if there is a way to establish if there were two such actors. Any ideas? --Jarekt (talk) 14:12, 21 August 2019 (UTC)

@Jarekt: The names are not the same. But in a case like this you should follow through to the original sources - VIAF etc. may have links to other information about them; if there's any news article or other work that lists them that might help. Searching Google books or might also turn something up. Presumably if they are indeed different people, the death date and perhaps birth date only really applies to one of them. ArthurPSmith (talk) 16:56, 21 August 2019 (UTC)
ArthurPSmith, thanks for pointing out difference in names, I did not noticed it. I did follow all the links I could find and I think they are all derivative of GND entry. Google search for term "Hermann Buttersack" finds no valid hits, nor does Google Books or Perhaps there are other places to search, but other than bare bones GND and mirrors I see no proof that Hermann Buttersack (Q55900412) ever existed. Most likely it is a version of Hermann Butterweck (Q18202241) with a typo. --Jarekt (talk) 19:36, 21 August 2019 (UTC)
That definitely sounds plausible. You didn't find the typo anywhere besides GND (and derivatives) then? ArthurPSmith (talk) 19:38, 21 August 2019 (UTC)
No the name is used only at GND and derivatives (VIAF, ISNI, CERL & Wikidata) and none of derivatives has anything about the person other than the bare bones that GND has: name, dates and occupation. --Jarekt (talk) 20:47, 21 August 2019 (UTC)
I think when this one first came up on Wikidata:Database reports/identical birth and death dates/1, we had a few similar ones, but for these others, VIAF/GND indicated that one name was an alias for the other.
It does happen with pairs that come up on Wikidata:Database reports/identical birth and death dates that names and dates get mixed up, without the two persons being the same.
For the pair discussed here, I had brought it up on Wikidata:Forum/Archiv/2018/11#Same_lifespan, but without much luck either. BTW, GND has some complicated way of indicating its source of their data. --- Jura 10:28, 22 August 2019 (UTC)

New tools and IP masking

14:18, 21 August 2019 (UTC)

Johan, one tool I would find very useful for patroling changes, is a single click undo button to reverse bad (malicious or careless) item merges. I see quite a lot cases where some fresh user merges 2 items (possibly using some tool or "game") which is plainly wrong. It takes a lot of work to restore two separate items and it is quite possible that other items linking to the merged items are never corrected properly. I know such tool has nothing to do with IP masking, but if you are looking for potential tools for resent change monitoring, that would be one I could really use. --Jarekt (talk) 19:50, 21 August 2019 (UTC)
Seconded. --Daniel Mietchen (talk) 03:19, 22 August 2019 (UTC)
It's easy if you do it right away, by reverting the two items. It's harder to do it a couple of years and a few hundred edits later, but that would also be hard to automate. Ghouston (talk) 10:40, 22 August 2019 (UTC)
I agree that a one-click tool for undoing merges would be very useful for Wikidata. Especially a tool that also takes care about undoing the changed redirects that happened as a result of the merge. If we had such a tool we could make it easier to discover how to merge items for new users on Wikidata by not requiring to activate a gadget which would be a major step forward. Having a system for the redirects of merges that doesn't rely on a bot would be very helpful for other installations of Wikibase besides Wikidata where there's currently no automatic way to get redirects moved after a merge.

      • @Adelfrank: If you set both family name (P734) and given name (P735), then you shouldn't need to manually define a DEFAULTSORT, the infobox will do it for you. In this case, I think it's a caching issue - you added the family name at about the same time as the infobox. In that case, try doing a null edit (edit the page, then save it without making any changes), or add "?action=purge" to the URL, in order to clear the cache. Thanks.

University presidents

I'm noticing a couple of different approaches for data about university presidents.

In some cases, an item is created for the specific position, such as President of Harvard University (Q19588706) and this is given as a position held (P39) statement on an item for a person (such as Drew Gilpin Faust (Q49128)). In other cases, the more general item university president (Q4376769) is used for position held, along with of (P642) to name the university (such as Edward John Ray (Q5343795).

Either approach seems valid, but is one preferred?

(I've also seen statements using occupation (P106) with either university president (Q4376769) or an item for a specific position, but that is flagged as a potential issue because university president (Q4376769) is not currently an instance of occupation (Q12737077).) Lrobare (talk) 21:36, 19 August 2019 (UTC)

Short answer (my view): probably the first of those - President of Harvard University (Q19588706) as a position held (P39) statement - since we tend towards increased granularity and because it supports easier queries. Ideally both approaches convey exactly the same information, although in fact the class trees for the two examples are currently worlds apart; Harvard President is a Rector which is a ..., and meanwhile a university president is something else altogether, the two meeting eventually at official (Q599151). So if subclass items such as President of Harvard University (Q19588706) are being relied on, the imperative is to square their class memberships with generic positions such as university president (Q4376769), else they become useless or positively harmful. --Tagishsimon (talk) 22:24, 19 August 2019 (UTC)
+1. Nomen ad hoc (talk) 22:27, 19 August 2019 (UTC).
I only create the entry President of Harvard University (Q19588706) if I am working on a list that has multiple entries, I do the same for Mayor of X and Commissioner of X and other positions. If I only have a single entry I use the second method with occupation (P106) filled in with the generic title. We could always have a bot create Mayor of X for every city in the USA, but almost everyone would have no entries. --RAN (talk) 03:16, 23 August 2019 (UTC)

Lists and positions

Cyprus Minister of Communications and Works (Q38112367) is position (Q4164871). Is it correct to connect this kind of items with a list like en:List of Ministers of Communications and Works of Cyprus? Or is it better to have separate items like list of Ministers of Transport, Communications and Works (Q66583238)? I think the second option is better because en:List of Ministers of Communications and Works of Cyprus is Wikimedia list article (Q13406463) and not position (Q4164871).

I don't speak it, but from the shape of the article, the linked page on zhwiki looks likely to be such a list - many different places and different images. Agree on converting this item to be a list. Andrew Gray (talk) 11:49, 20 August 2019 (UTC)
@Liuxinyu970226: given that you seem to be interested in the item I think it would be straightforward if you do the conversion to list article. Is there anything about that, that you don't feel comfortable with, so that you want that someone else helps you? ChristianKl❫ 16:47, 20 August 2019 (UTC)
@ChristianKl, Andrew Gray: why not call (and separate) that zhwiki article as Wikipedia article covering multiple topics (Q21484471) instead? There has also parks that are not met both zhwiki and Wikidata notability policies to have items (e.g. if your home has a garden that named "Zhongshan Park" by yourself). --Liuxinyu970226 (talk) 22:51, 22 August 2019 (UTC)
@Liuxinyu970226: Looking at them, I think all the articles are lists of parks - some only have a few entries but none of them seem to be about one specific place. So it should be fine to convert the item. Andrew Gray (talk) 10:12, 24 August 2019 (UTC)

different meanings of the word for the direction left (Q18340392)

This item, different meanings of the word for the direction left (Q18340392), is used to classify a specific set of disambiguation pages relating to word senses (not homographs or homophones). it should still have some properties, but I am utterly stumped as to which property+item combinations are proper. Circeus (talk) 19:15, 23 August 2019 (UTC)

IMHO, this item should not exist. It isn't linked to any category or wiki article; the concepts "left behind" and "leaving" have nothing to do with direction. If anything it belongs in lexemes. - PKM (talk) 21:30, 23 August 2019 (UTC)

Probable duplicate items

I'm pretty sure and represent the same thing and should be merged. I do know how to do merges, so no need to point me there, I just don't have enough knowledge about the royal family of Jordan to be absolutely certain they are actually not somehow different concepts that need to be separately maintained.

Pictogram voting comment.svg Notified participants of WikiProject Ontology @Multichill, Jheald, Jane023, Spinster:

Our modeling of pigments is all over the place. I'd like to find a consensus that works for both chemistry and art materials communities of practice. Here are some current examples:

  • alizarin (Q267813) AKA Turkey red, pigment red 83 <instance of> "chemical compound" matched to AAT's "colorant for dye and pigment".
  • pigment blue 16 (Q414162) AKA phthalocyanine <instance of> "chemical compound" with no mention of pigment despite the labels.

I think we should have some agreement on these points:

  • The named color should be a separate item from the pigment (I think we've reached consensus on this before).
  • Should the chemical compound and pigment be the same item? If so, should the model be <instance of> "chemical compound" and <instance of> "pigment" or something else? (We might have <use>="pigment", but does this make querying for pigments counterintuitive?)
  • Should pigments be linked to their named colors with <named after> on the color and <color> on the pigment?

And lastly, is there enough interest in this topic to make a WikiProject (maybe dyes and pigments) where we can discuss and document best practices? - PKM (talk) 22:04, 23 August 2019 (UTC)

Please no new Wikiproject: already now too few contributors are involved in existing Wikiproject and we are missing an overview of the problems, partially due to the fact that each one is working in his corner.
To come back to the mentioned problem, my first question is: What is a pigment ? To solve ontological problem we need definitions.
If I take the English definition of pigment and chemical compound I have the following:
Can we link material and chemical substance ?
  • base material (Q214609): substance that can occur in different amounts, all with some similar [mixture of some] characteristics, and of which objects can be made up
  • chemical substance (Q79529): matter of constant composition best characterized by the entities (molecules, formula units, atoms) it is composed of
It seems we can find a link but we need to unify the upper classes of both items before to be able to merge anything. But I think a pigment is a chemical substance but not a pure chemical substance: some pigment are mixtures of several chemical compounds (chemical compound is a pure chemical substance). So if we want to model that case too we can't systematically merge pigment and chemical compound. I think we have a similar situation with drug: there are often one chemical active substance, but in really a drug is a mixture of several chemical compounds.

Are there a way to block scientific articles from showing up in search results?

It often makes it quite hard to find what i'm looking for. --Trade (talk) 03:01, 18 August 2019 (UTC)

Agree, or have an option to sort them to the list bottom. The usefulness of autocompletion completely vanishes if objects only show up if their labels have been written out. --SCIdude (talk) 06:19, 18 August 2019 (UTC)
See also Wikidata:Requests_for_permissions/Bot/LargeDatasetBot, which will import 12 million more such articles. − Pintoch (talk) 09:41, 18 August 2019 (UTC)
On Special:Search, you can append -haswbstatement:P31=Q13442814 to your searches to exclude all items with instance of (P31): scholarly article (Q13442814). That should already help a lot. Unfortunately, it does apparently not work if you type the search term directly into the search form on the upper right corner. --MisterSynergy (talk) 13:07, 18 August 2019 (UTC)
In other words, autocompletion should be configurable the way Special:Search is. --SCIdude (talk) 13:40, 18 August 2019 (UTC)
@MisterSynergy: Are you referring to the autocomplete dropdown, or to making a Special:Search query by typing text into the search box and pressing Enter? If the latter, you can additionally get item results only by prefixing the search query with ": " (Special:Search defaults to properties only for me, and I'm not sure how to change that; if this is happening for you then this would work). Jc86035 (talk) 07:55, 19 August 2019 (UTC)
Generally the search algortihm tries to rank scientific articles lower then other items. Can you give example of searchers you did where you think that the scientific articles get ranked to highly? ChristianKl❫ 19:12, 18 August 2019 (UTC)
@ChristianKl:*typing "neuropatholog" --> medical specialty at #30 after roughly 39 scientific articles but full "neuropathology" --> medical specialty at #1 --Trade (talk) 11:57, 25 August 2019 (UTC)
@ChristianKl: E.g. aiming at the object labelled "angiotensinogen", typing "angiot" gives a drug object at #1, the rest are all scientific articles. The target shows up with "angiotensino" but only at #5 after 4 articles. --SCIdude (talk) 06:09, 19 August 2019 (UTC)
From looking at that search, that does seem wrong. I'm not sure why the search behaves the way it does. It would be good if we would have >10 examples like this of where the search engine works poorly and give it to the developers to tune the search engine to give better results. ChristianKl❫ 07:02, 19 August 2019 (UTC)
@ChristianKl: As you wish (from my field):
  • typing "kissp" --> only scientific articles but full "kisspeptin" --> gene at #1
  • typing "cathel" --> only scientific articles but "cathelicidin" --> group of peptides at #1
  • typing "preproe" --> only scientific articles but "preproendothelin-1" --> non-article items at #1-4
  • typing "proglu" --> only scientific articles but "proglucagon" --> protein at #1
  • typing "preproi" --> protein at #3 after 2 scientific articles
  • typing "apeli" --> only scientific articles but "apelin" --> six non-article items <==== !!
  • typing "thymosin" --> only scientific articles but "thymosin beta" --> 3 non-article items, enough? --SCIdude (talk) 07:36, 19 August 2019 (UTC)
I think that's a good portion for the drug items. If there's a different items that have a similar problem it would be great to have example items of the problem as well @Lea_Lacroix_(WMDE): can you interface with the development team about tuning the search algorithm again? ChristianKl❫ 07:45, 19 August 2019 (UTC)
it should also help the search algorithm if wi link articles to their main topics. It’s a lot of work but as a very good hint of topic for the article is that the subject of research is present in the article title, it should be able to create a wikidata game or something like that to help to do that. If the topic become used in such statements, it should be higher ranked in the results, or am I being naive ? (of course it’s not an immediate answer to the problem). author  TomT0m / talk page 19:32, 18 August 2019 (UTC)
A simple query shows quite promising results. author  TomT0m / talk page 19:48, 18 August 2019 (UTC)
I'm uncertain whether we get millions of instances of people playing the game. It would be nice to have such a game but I don't know if it will move the needle. More direct Zotero integration would be great for having more main subject claims. ChristianKl❫ 07:02, 19 August 2019 (UTC)
I think it's pretty obvious from the apeli/apelin example alone that articles get ranked first and get only overtaken if the item is spelled out in full, which completely nulls the value of autocompletion. That's a bug in my dictionary. --SCIdude (talk) 07:47, 19 August 2019 (UTC)
As far as I remember we introduced a punishment for items types that come from big imports. Items about the proteins are supposed to rank less well then some other items. Songs and movie titles are behave in a similar way. It would be intersting to know if the problem appears the same way for normal items. ChristianKl❫ 09:35, 19 August 2019 (UTC)
I can understand that (1 million) proteins are ranked below less numerous objects. Scientific articles however are many millions, so by that logic should be ranked to the very bottom. --SCIdude (talk) 13:21, 19 August 2019 (UTC)
I do agree, my point was that it's useful to know whether the problem also exists for other items and that's why it would be good if the people who had problems at commons would also add a few examples, so that everybodies usecases are covered when the algorithm gets updated. ChristianKl❫ 15:30, 19 August 2019 (UTC)

QuickStatements just needs a CSV (or tab-delimited?) file as input, right? Those are industry-standard formats, with several million different tools which can generate them. They're totally not limited to Excel. —Scs (talk) 02:31, 25 August 2019 (UTC)
I quite like the way the WE-Framework gadget looks and works. If you gave it the ability to customize the properties available, save statements and run batches i could totally see it work. --Trade (talk) 03:34, 25 August 2019 (UTC)
Thanks for the info! --D-Kuru (talk) 11:49, 24 August 2019 (UTC)
Why not create an empty item, merge the original into it, and restore the original, as described in Help:Merge? --SCIdude (talk) 12:18, 24 August 2019 (UTC)
I think I saw some user do that and then edit only the English label/description. duplicate_item.js can lead to this as well.
BTW, User:Matěj_Suchánek/moveClaim.js can create a new item .. and allows to just copy statements one needs. --- Jura 12:34, 24 August 2019 (UTC)

Problems of bibliographic records

w.r.t (Q66724823)

  1. What's the difference between OCLC control number (P243) and OCLC work ID (P5331)? Please add this book's OCLC number 711513523.
  2. Is there a bot that would crawl worldcat and fill up info according to OCLC no. or ISBN?
  3. Searching an item by ISBN is too user-unfriendly. Take the example of ISBN-13 La Fraternité de l'Anneau (Q22137041), searching 9782267027006 would not find it. Seriously? Most lay users would not care about the dashes.--Roy17 (talk) 14:39, 24 August 2019 (UTC)
@Roy17: several things are very strange for this item. First is it a work or an edition? It seems to be an edition but which one? on Commons/Internet Archive, this is the 1988 edition with an ISBN-10 but you added an ISBN-13 (which is for editions after 2007, I corrected this ISBN to add the dashes but I can't find it in any database). For this identifier "711513523", it's a OCLC control number (P243) (for edition) and not OCLC work ID (P5331) (for work).
For the search, true it should be improved to give results even if you input without the dashes; that said, the ISBN numbers should always be stored with dashes (removing dashes is super easy, adding them can be quite tricky and almost impossible to do automatically). @Lea Lacroix (WMDE): could it be possible? (I vaguely remember that CirrusSearch has option for this but I can't find it…)
Cdlt, VIGNERON (talk) 12:33, 25 August 2019 (UTC)
@VIGNERON: thx a lot! I wanted to add the oclc no., but didnt know which to pick, so copied an ISBN. Since I intend to add a record from worldcat, oclc no. is reliable but isbn might not be, so I edited the item.--Roy17 (talk) 12:47, 25 August 2019 (UTC)
@Roy17: no problem, I added a instance of (P31) and the ISBN-10 (P957). PS: for the name of the Commons cat, should it be "sheng wu" or "shengwu"? Cheers, VIGNERON (talk) 13:59, 25 August 2019 (UTC)
@VIGNERON: the current name is in pinyin character by character, so it is sheng wu. How exactly should Chinese book titles be transliterated is not resolved yet on Commons: c:special:permalink/363319893#Categories_for_individual_Chinese_book.

How do we model pen-names?

We have an item Shōzō Numa (Q3959910) who is a pen name of Tetsuo Amano (Q3519206). Tho items have different VIAF numbers and some other identifiers. Should we use one or two items to model this? --Jarekt (talk) 22:28, 24 August 2019 (UTC)

List the alt identifiers under the real name with a stated as (P1932) statement and criterion used (P1013) pen name (Q127843)? (Typically this would be a reason for deprecation (P2241) statement instead of stated as (P1932), but I don't think that's appropriate here.) Circeus (talk) 05:32, 25 August 2019 (UTC)
Shōzō Numa (Q3959910) is shared pseudonyn of unknown authors. Some reference said Tetsuo Amano (Q3519206) is one of them.--Afaz (talk) 07:42, 25 August 2019 (UTC)

"Organization of formation"

I noticed it is a constraint error that the organization NAFS(k) (Q10593756) has location of formation (P740) set to the school Nya Elementar (Q10604257). It's because the school is not a geographical object (Q618123), which makes sense, because a school could change its physical location and still continue as the same entity. So it would be correct to replace this with a geographical object where the school was located. But still, is there a valid way to store that the foundation was at that school? Pst (talk) 06:09, 25 August 2019 (UTC)

The proper way would probably be to create a new item for the school building and use that one as the value for location of formation (P740). --Kam Solusar (talk) 23:43, 25 August 2019 (UTC)

Merge Maple Lake Municipal Airport Error

When trying to merge Q1030802 and Q35278441 I get an error "Error while "Please wait...": A conflict detected on cebwiki: Maple Lake Municipal Airport (Q1030802) with cebwiki:Maple Lake Municipal Airport, Mavencamp Airport (Q35278441) with cebwiki:Mavencamp Airport"

Any ideas how to fix this?

cebwiki has two different articles. Wikidata items can only have one. So either one is wrong, or both are the same and need to be merged first. --SCIdude (talk) 05:31, 26 August 2019 (UTC)

In GNIS ID (Q19832959) (the source from where geonames imported, and then from where ceb imported) there are both entries, but notably the Mavencamp airport is listed there as historical. So maybe the airport was relocated? When checking in Google Maps, there's just an empty field at the historical location. Ahoerstemeier (talk) 07:47, 26 August 2019 (UTC)

Wikidata weekly summary #379

Category:In Progress datasets

Seems there isn't much going on there. Some users create pages there and then vanish (or maybe expect something to happen). Samples:

Shall we archive or delete pages that don't even link to a dataset? Pages have a lot of text, but most is template generated.

It seems to be me that project chat would be a better point of entry for people interested in doing an upload. --- Jura 18:38, 26 August 2019 (UTC)

Applications for the Wiki Techstorm 2019 in Amsterdam are now being accepted


Hello everybody,

From today, until 8 September, the applications for the Wiki Techstorm 2019 will be open.

Dutch Wikimedia volunteers are organizing together with Wikimedia Nederland, this time in Amsterdam on November 22nd and 23rd 2019, and we are looking for enthusiastic Wikimedians (and GLAM-mers! and technical non-Wikimedians!) who want to be there.
The Techstorm stems from an initiative of the Dutch Gender Gap group, to promote women's participation online in Wikimedia projects. Although this is still our foundation, we are now offering a low-threshold introduction to the world of Wikidata, Wikimedia Commons and linked open data to a wider audience.

Do you recognize yourself in the following categories?

  • Beginning or experienced developers with an interest in Wiki projects;
  • Experienced Wikimedian who wants to learn (more) about the technique behind Wiki projects;
  • Data specialist, information specialist and digital collection manager working in the heritage sector and/or library sector who would like to learn (more) about sharing collections via Wiki projects?

Then sign up for participation!

More information about the Techstorm can be found on information about last year's Techstorms can be found on Mediawiki.
There are several chapters who offer scholarships for travel and board.

On behalf of the organization a warm greeting,
Ciell (talk) 19:50, 26 August 2019 (UTC)

@Ciell: good news! You expect to accept a lot of them? :-) Multichill (talk) 19:56, 26 August 2019 (UTC)
Hi Multichill! Though we'd love to accept every application off course, we have to limit our number of participants to 60 people. This is now our third time organising a Techstorm and we think we are really developing a formula which creates retention and growth, as well in diversity as in numbers, within the communities, and we hope that we can inspire other chapters to adopt the concept.
Please get in touch if, after reading through our documents and recommendations on mediawiki, you would like to organise a Techstorm in your home country and have questions or need help.
Kind regards, Ciell (talk) 20:03, 26 August 2019 (UTC)

Requesting help

Dear fellow members of this wikiproject, I am new here (I am older in the English wikipedia), so I want to request your assistance. I have created 2 Items, the second is the one I need help. (here). That Greek company, FARCO, was brought by Chrysler and was renamed Chrysler Hellas S.A.. I chose the "replaced by" statement, I typed that but it said it is invalid. I chose the "unknown value" and "no value" options in the small box, but now it displays no place to type. Can someone help me out? Best regards, Enivak (talk) 21:24, 26 August 2019 (UTC)

@Enivak: What is the Wikidata {{Q}} code for the item that FARCO (Q66763562) was replaced by (P1366)? –MJLTalk 21:46, 26 August 2019 (UTC)
MJL You mean Chrysler Hellas S.A? If yes, I think it does not exist, this is generally the problem (has no code) Enivak (talk) 21:49, 26 August 2019 (UTC)
@Enivak: Ah, well then you'll likely need to make that item as well. Basically, the property replaced by (P1366) requires a second item in order to make a complete statement. Alternatively, you can make "Chrysler Hellas S.A." an alias like I previously did. Then you can add parent organization (P749) is Chrysler (Q181114). Does that help explain things? –MJLTalk 21:56, 26 August 2019 (UTC)
MJL I will try to see if that helps, if not I will post it here.Enivak (talk) 22:01, 26 August 2019 (UTC)

PHP script to run a Query gets 403 error

I'm taking my first stab at using a PHP script to read results of a query against Wikidata. When I use a GET URI in a browser window I have no trouble, but when I use the PHP script provided in the CODE link on the query page, I get a 403 http error. Is this a permissions errors (as 403 would suggest)? Do I need an API code or some such thing? A request for permissions? The script I'm working on is more interactive than what I'd call a bot, but maybe the bot rules apply and I need to apply for bot permissions? The fact that the query results page includes the PHP code makes me think it ought to "just" work. Any advice?

Deletion of birthdates

On Trygve Ottersen (Q66424846) the birthdate have/was been deleted with the reason please provide a reference for this date . Adding a birthdate to a person gives Suggestions citation needed constraint Statements for date of birth should have at least one reference. Is this an indication that whenever I come across an unrefferenced birthdate on Wikidata I shall delete it, or should I just await and have confidence that sooner or later an Reference will be added. My opinion is that even if no reference is provided and it is a suggestion someone have given this date because they hade found it somewhere?. imported from Wikimedia project (P143) can not be used here since the date first have been deleted on the wikipedia and then deleted in Wikidata. Pmt (talk) 12:55, 17 August 2019 (UTC)

Birthdates are very rarely incorrect in Wikipedia / Wikidata, because the subject of a biography (or a family member) typically corrects it if he or she sees that it is wrong. All statements should have a reference, but I wouldn't blindly delete a birthdate without a reference, unless I had specific reasons to believe that it was incorrect. Regards, Kjetil_r (talk) 13:44, 17 August 2019 (UTC)
The subject of a Wikidata item very rarely sees it and therefore is unlikely to correct an error - we should not rely on that happening. Nikkimaria (talk) 00:17, 18 August 2019 (UTC)
But they will see the connected wikipedia lemma, and correct it there. From there we could add it to a list where the dates between different wikipedias and wikidata (and other sources) differ. More sources means more checks so more chances to find errors, and improve the contents from there. Edoderoo (talk) 14:20, 18 August 2019 (UTC)
English Wikipedia does not allow the subject of an article to edit the article. In fact, it is not just "first person" banning, it is any personal involvement with the subject of an article. That means the offspring, or the media agents (for a celebrity), or even me, who was blocked for a COI when I tried to correct the spelling of my ex-girlfriend's son's name. Quakewoody (talk) 16:20, 18 August 2019 (UTC)
When we had the RfC about living persons the community decided against having a bot that goes and automatically removes privacy sensitive statements. This suggest that there's no desire to have people go out and simply remove all uncited privacy sensitive statements. ChristianKl❫ 17:51, 18 August 2019 (UTC)
@Pmt: (because of this edit) Deleting all birthdate statements that don't have at least one reference is one thing, removing a birthdate statement because one was not able to verify it with reliable sources another. Wikidata statements should generally be supported by referenceable sources (see Help:Sources). There are some exceptions, but I don't think that this birthdate is one of them. There are even stricter rules for biographies of living people (see Wikidata:Living_people). Please provide a reference if you want to keep this statement. - Valentina.Anitnelav (talk) 17:56, 20 August 2019 (UTC)

@Pmt: Help:Sources lists some kind of sources that may be appropriate references (books, scientific papers, databases, etc.) and in Wikidata:Verifiability you can find more information about the relevance of sources. Help:Sources explicitly excludes Wikipedia as an appropriate source ("Please note that while pages on Wikipedia (and other Wikimedia sites) should and can be added as sitelinks, they are not appropriate as sources for Wikidata statements."). If a source is a "reliable" or "referenceable" or "appropriate" or "authoritative" source does also depend on the context and may be subject of debate, but Bibsys seems quite appropriate to me for this statement.- Valentina.Anitnelav (talk) 18:42, 20 August 2019 (UTC)

Petscan help

A while ago someone who was more tech savvy than I am set up this pet scan for me, so that I could just enter category name from the English Wikipedia, and it would tell me corresponding articles on the English Wikiquote that were in the same category as defined by Wikidata. It no longer seems to be working and give an error: "manual wiki requested as output, but not set". I'm afraid I'm not pet-scan-inclined enough to know what this means or how to fix it. GMGtalk 12:56, 23 August 2019 (UTC)

@GreenMeansGo: It looks like there's some changes to the way it handles "manual sources" in the new version (you need to specify the wiki in a different place), which is why it's throwing an error. However, weirdly, the new one doesn't seem to like enwikiquote - you can do the query for commons or enwikisource, but not quote. I'll file it as a bug and let you know the URL for the updated PetScan when it's resolved :-). (The answers will be the same, but hopefully the new one will run a bit faster & more reliably for you.)

To quickly walk through how this works so you can reconstruct it in future if you want:
  • tab 1, "Categories", tells it to find all pages, on enwiki, which are in "Category:American Nobel laureates". Depth = 0 means it will not include any subcategories.
  • tab 4, "other sources", tells it that we want the results to be given as enwikiquote pages - this is the "use wiki" option at the bottom. It will thus only give answers which have a valid enwikiquote link.
Everything else is left blank/default. Andrew Gray (talk) 12:24, 27 August 2019 (UTC)

Nth generation lineal descendant

Is there a way to model lineal descendants of the Nth generation from an ancestor in relative (P1038) statements? lineal descendant (Q19671714) can be used as a value of type of kinship (P1039) qualifier, but how to provide information for a specific generation? For the 3rd, 4th, 5th and 6th generation, we have specific items such as son's son (Q23684609), great-grandson (Q19682170), great-great-grandson (Q19682183), and great-great-great-grandchild (Q53277248), but how about other generations? Should we create items for each of them? For example, H. H. Kung (Q631416) is a 75th generation descendant of Confucius (Q4604). What would be the best way to model it?

Are Grammies instance of (P31), subclass of (P279) or part of (P361) of Grammy Award (Q41254)? Because now there are all types... --Infovarius (talk) 09:21, 27 August 2019 (UTC)

I think subclass of (P279) should be used all the way through, except to use instance of (P31) for an item describing an individual award event (X person received Y award on this date) - which I don't think we typically add as items anyway, rather using statements with award received (P166) on the item for the person. So basically, it should probably be subclass of (P279) everywhere for awards. ArthurPSmith (talk) 13:48, 27 August 2019 (UTC)

The algorithm and the constant are two different concepts and thus merging them shouldn't happen. In this case you will get an error that comes from the fact that frwiki has articles on both topics. ChristianKl❫ 11:13, 27 August 2019 (UTC)

Removed or uncertain archaeological sites

For the next Wiki Loves Monuments competition, we have imported thousands of archaeological sites in Finland. We would like to be able to mark those of them that have been listed but marked as removed or uncertain to be able to use that for filtering them out from the lists. Which method to choose? Remove them entirely from Wikidata, or describe them with a property. Which one? – Susanna Ånäs (Susannaanas) (talk)

It depends on the situation:
Ayack (talk) 12:37, 27 August 2019 (UTC)
Answering both: The two types of sites that should be marked are
  1. The site is possibly an archaeological site rather than a pile of rocks
  2. The site is an archaeological site, but it has either been demolished or removed and relocated

Vision and strategy papers for Wikidata and Wikibase are published

Hi everyone :)

More than 7 years ago we started the development of Wikidata. We started out with the main goal of building a central data store for Wikipedia. Very quickly we expanded to also covering the other Wikimedia projects. Then came the interest from people outside Wikimedia to use Wikidata’s data to build their own apps, websites, visualisations and more. And last year we witnessed a significant interest in Wikibase, the software behind Wikidata. This means our work has expanded very significantly from what we started out with. We noticed that more and more people need clarity and certainty about where Wikidata and Wikibase are going. Because of this WMDE and WMF started discussing this more deeply and wrote down a lot of the things we have been talking about in the Wikidata and Wikibase communities over the last years.

The result of these conversations include one product vision paper and three product strategy papers that we are publishing today:

  • Vision: This paper gives a high-level overview of where we’d like to see Wikidata and Wikibase evolve and grow, based on the work of the past 7 years and many conversations with community members, movement partners, and other stakeholders.
  • Wikidata for Wikimedia projects: This paper dives deeper into how we see Wikidata developing in the context of the Wikimedia projects and how it can better support the projects.
  • Wikidata as a platform: This paper explores the value of Wikidata as a source of data for others outside Wikimedia to build upon.
  • Wikibase Ecosystem: This paper goes deeper into the idea of the Wikibase Ecosystem, a network of Wikibase instances which share data and other capacities.

I would love for you to read these papers now and give your feedback. We are collecting feedback until the end of October and will then integrate it as appropriate into a second iteration of the papers.

The papers are published at m:Wikidata/Strategy/2019. Please leave your feedback and questions on the associated talk page.

I am looking forward to reading your input.

Alternative ship name: qualifier?

Hi, after editing the item about the vessel Dida, I got warning signs about the property 'Alternative name' that I had chosen to represent this information about the various names of the vessel:

  • Amstel (1998)
  • Fort Mingan (1995)
  • Nordbec (1970)
  • Oslo (1969)
  • Dida (1962)

The information blob says that 'Alternative name' should only be used as a qualifier, but I can't find the property to which this property belongs. Anyway such a qualifier would need a subqualifier for the year.

I believe it would be best to create a property (re)name or christening with qualifiers for date, place, the organisation (shipping line, navy) that ordered the (re)christening, and possibly the ceremonial christener and more. Merchant vessels are sold frequently as illustrated above and subsequent shipping lines generally apply new names.

Maybe there is already a solution in place I am not aware of? Thanks! — bertux 12:50, 27 August 2019 (UTC)

You should use official name (P1448) with start time (P580) and end time (P582) instead. Ayack (talk) 13:05, 27 August 2019 (UTC)
Actually, since there are various properties used (short name (P1813), native label (P1705), etc.) you should ask your question to Wikidata:WikiProject Ships. Ayack (talk) 13:14, 27 August 2019 (UTC)

Use P131 as a qualifier for a settlement ?

It seems that there's a lot of misuses of P131 as a qualifier.
I think there's 2 typical misuses :

  • When P131 point to a division who is containing the qualified statement, as I can see, by example, in P19 :
    SELECT ?lnLabel ?laLabel ?item
      ?item p:P19 ?n .
      ?n ps:P19 ?ln .
      ?n pq:P131 ?la .
      SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    Try it!
  • When P131 point to a subdivision of the qualified statement, as I can see, by example, in P17 :
    SELECT ?lnLabel ?laLabel ?item
      ?item p:P17 ?n .
      ?n ps:P17 ?ln .
      ?n pq:P131 ?la .
      SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    Try it!

I think that in the first case, the qualifier can be delete. But before doing this on ~23,000 items, the French chat propose to me to expose the situation here to have more feedback.
So, what do you think about that Simon Villeneuve (talk) 20:53, 27 August 2019 (UTC)

It can be useful when the parent division is not obvious at the time used in a statement. Some Wikipedias probably want (for infoboxes) but can't derive a full chain of hierarchy at specific moment of time so they depend upon such information. --Infovarius (talk) 21:52, 27 August 2019 (UTC)
I'm curious (as I believe it is an overused property even as a main statement): are there any legitimate use of located in the administrative territorial entity (P131) as a qualifier to begin with? Circeus (talk) 23:15, 27 August 2019 (UTC)
Take Maade (Q1882240) - while using located in the administrative territorial entity (P131) as a qualifier for country (P17) is IMHO nonsense, it is totally valid for the mouth of the watercourse (P403) statement - and I also added it a few times for rivers in past that way. Ahoerstemeier (talk) 07:47, 28 August 2019 (UTC)
I think it can be useful for situations like with Middlesbrough (Q2673020) where located in the administrative territorial entity (P131) is North Yorkshire (Q23086) but on the next level it has alternatives. In most other cases, this is absolutely not necessary. Сидик из ПТУ (talk) 10:43, 28 August 2019 (UTC)
@Сидик из ПТУ: I don't understand : P131 isn't used as a qualifier on Q2673020. Simon Villeneuve (talk) 13:24, 28 August 2019 (UTC)
Yes, but I think this would be a great solution to build the correct geo-chains in similar cases. Using P131 here like a switch is better than applies to part, aspect, or form (P518) on the next level because we can find more difficult cases where such refinements will be needed for each farm or rock, not just for five districts. For example, (Q46706877) is situated on territories of three districts (read Ukrainian article). Сидик из ПТУ (talk) 13:51, 28 August 2019 (UTC)

Audio engineer

There seem to be differning uses of audio engineer (Q128124) (in English: "audio engineer", alises include "sound engineer") for both people who engineer speakers and the like, and people who assist record producers. Is there a better alternative for one of these, or do we need an additional item? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 15:15, 28 August 2019 (UTC)

@Pigsonthewing: I would love to see "recording engineer" separated out, at least. In general this area could do with some fleshing out by someone who knows the field. On a side note, the term "engineer" is used very loosely by English speakers while (at least in) Scandinavia it's a protected title that comes with a certain education. So what you call engineer, would often be a mere "technician" to us ;-) Moebeus (talk)

Words with a masculine and a feminine form

Beeyan Rachmat04 Fadirra Martin

Pictogram voting comment.svg Notified participants of WikiProject Language

In some languages such as Italian, French and German, nearly all proper names, occupations, nationalities and adjectives (maestro - maestra; lehrer - lehrerin; docteur - docteure; bianco - bianca) have a masculine and a feminine form. Currently, Wikidata has a lexeme for each form, but there's no link between one form and the other. What's the best solution:

  • Create "feminine form", "masculine form" and "neutral form" properties to link one form to the other;
  • Create only one lexeme for such words and point out the masculine and feminine forms in the Forms section.

Lore.mazza81 (talk) 00:09, 26 August 2019 (UTC)

You yourself used the term "form" to describe the differences, so it seems clear to me they should be considered different "forms" of the same lexeme. There may of course be other opinions on this. If somebody has a good reference, I'm sure this has been discussed in the lexicographical community! ArthurPSmith (talk) 17:33, 26 August 2019 (UTC)
@Lore.mazza81: Swedish has two, three or four "forms" depending on how you define the model. Add to that "gender-free form", which is none of these four (or was is five?). I would therefor prefer a property with the label "form" where you could add whatever you like of any form there could be in the wide world. IP (Hej!) 19:51, 26 August 2019 (UTC)
@ArthurPSmith: I prefer this option, too. It seems to me the best one also because it makes easier to use the "translation" property in the case of words that have no gender in a language, but many of them in another.
For example, the english word "white" can be translated as "blanco" and "blanca" in spanish, as "bianco" and "bianca" in Italian, as "blanc" and "blanche" in French, as "weiß" and "weiß" in German...
@Sextvå.tvånoll.ettsjunoll.sjufyra: What's the difference between what you propose and the "Forms" section?--Lore.mazza81 (talk) 01:07, 27 August 2019 (UTC)
I'm not sure if the samples from different lexical categories of random languages are really equivalent. Translations would generally be between specific senses of lexemes. Some languages have countless forms for most words, so you can't easily define them in the same way as in other languages. It should be possible to find an equivalence between languages independently of the chosen approach. --- Jura 02:40, 27 August 2019 (UTC)
@Lore.mazza81: My main point is that linking to the feminine form by a specific property does not make much sense. Then you have to create a new property for all forms there are in the universe. As I said, Swedish has more forms than only "feminine", "masculine" and "neutral". When I was in school, we learned four forms, the forth was a "second neutral" form. My sister learned two forms: neutral and "non-neutral". In practise we today use a "gender-free" form that isn't neutral. That expands your model of three new properties to six only by expanding into one single language. IP (Hej!) 08:41, 27 August 2019 (UTC)
@Sextvå.tvånoll.ettsjunoll.sjufyra: I don't like the property approach either.
@Jura1: In my opinion the spanish words "blanco" and "blanca" are different forms of the same lexeme, whose sense (or at lease one of its senses) is equivalent to (one of) the sense of the English lexeme "white". On the other hand, if we consider "blanco" and "blanca" two different lexemes (the current approach), none of their senses can be considered equivalent to any sense of the "white" lexeme.--Lore.mazza81 (talk) 02:31, 29 August 2019 (UTC)
I'd think Spanish would make just one entity for this adjective. We probably didn't quite get to the point to seek a way to flag senses of adjectives that apply to just some of the forms. --- Jura 08:14, 29 August 2019 (UTC)

Merger request (kind of)

There are two (2) overlapping items, Q1045852 and Q10809927, the former includes any articles in various language and the latter only the Vietnamese-language article w:vi:Quan (tiền), well "Quan (tiền)" is about the currency unit "String of cash coins", going down the list of articles from the item "Q1045852", the German, Lithuanian, and Korean articles are exclusively about the "貫" weight measurement unit used for cultured pearls, while the English, Mandarin, and Japanese are all primarily about the currency unit, but also fully explain what the unit of mass is. Obviously the Vietnamese article should be in the same list as the English, Mandarin, and Japanese articles as well as the Wikimedia Commons (Commonswiki) article while the German, Lithuanian, and Korean language articles are about a concept which is mentioned in all other articles except for the Vietnamese one.

While the simplest solution would be merging these two items, the scope of the articles overlap in some cases, but not in others, what would be the best solution here?

Maybe the English, Mandarin, and Japanese Wikipedia's should have separate articles for the weight unit, but this seems to be a bit more complicated than that. -- Donald Trung/徵國單  (討論 🀄) (方孔錢 💴) 19:29, 28 August 2019 (UTC)

In theory the Japanese language article could become a disambiguation and be split into the articles "w:jp:貫文" and "w:jp:貫目", the same could also happen on the English language article and the Mandarin one (which contains the least information on the Japanese unit used in the cultured pearl-industrial complex). -- Donald Trung/徵國單  (討論 🀄) (方孔錢 💴) 19:33, 28 August 2019 (UTC)

Interesting topic. We can not force Wikipedias to split or merge articles, it depends only their own policy and the size of the content in that language. To me it sounds like a valid case for merging, provided we specify the right instance/subclass statements. Cheers! Syced (talk) 03:18, 29 August 2019 (UTC)

Storing in Wikidata the preferred language variant used on Wikipedia?

Hi all,

I was asked a question by User:Boshomi that I’m not too sure about, so relaying here :)

On the German-language Wikipedia, editors decide when an article should use Austrian German (Q306626) spelling, and add it to a tracking category ( (Q32078103)) − that’s about 17K articles.

(Worth noting that this use-case is not specific to German-language Wikipedia − English-language Wikipedia also has Category:Wikipedia articles by national variety of English (Q8110126))

User:Boshomi was wondering whether it would be possible to somehow store that information on Wikidata. It would then be possible to use that information on the article (for example for formatting the dates automatically in Citation templates, as I understand it).

As I understand it, whether an article 'should' use Austrian-German spelling is not something that can easily be inferred from the already existing properties (such as country (P17) or country of citizenship (P27)) − it’s an editorial decision made by the editing community based on several factors. It would then need to be stored as its own thing.

On the face of it, my first thought was that we store here statements about the entities, not about the Wikipedia articles about it (except for the Badges). That said, we do have several Wikidata property about Wikimedia entities (Q51118821). So I am relaying the question here in order to get a more definite answer :)

Thanks, Jean-Fred (talk) 16:29, 28 August 2019 (UTC)

To clarify the use case: that information is stored Wikipedia-side using tracking categories, but this is not accessible from other templates used on the page − or at least it’s not clear how to do so: maybe there is some Lua function to do exactly that :) Jean-Fred (talk) 16:37, 28 August 2019 (UTC)
I looked for a lua function and for magic words, but I could find nothing. The easy way is invoke a property from wikidata. –Boshomi (talk) 18:03, 28 August 2019 (UTC)
It seems to me like an editorial decision made at dewiki based on dewiki policy that only concerns dewiki (other Wikis might make different decisions about how a name is supposed to be spelled). Such information seems to me like it's ideally stored in a dewiki tracking category and not on Wikidata. ChristianKl❫ 09:27, 29 August 2019 (UTC)
@ChristianKl: Yes, it is an property of a dewiki article. The tracking category exits (Q32078103). The use case for wikidata is template programming:
 if invoke dewikiLang=de-AT then Jänner else Januar end
 if invoke dewikiLang=de-CH then replace(sometextwith_ß , ß, ss) end
The result is a text output of templates that fits to the article, and there is no need for editing tousends of articles to put same extra parameter into each templates transclution.–Boshomi (talk) 18:03, 29 August 2019 (UTC)
  • May be these wikis should create appropriate "badges" which could be assigned to such articles? --Infovarius (talk) 20:14, 29 August 2019 (UTC)

Modeling the ratings and reviews of critics

Is anyone aware of a precedent for general modeling of quality ratings and reviews by critics?

Expert organizations and commentators routinely rate and review media, places, products, and organizations. Here are some examples:

Every big budget, book, music collection, video game, and movie gets critic ratings from lots of publications. In academia all sorts of individuals, organizations, and journals rate and review everything that is the subject of human discourse. Citizens, corporate entities, and government rate and review each other continually.

What discussion already exists about bringing this into Wikidata? I am especially interested in brief ratings, either numbers on a scale, a grade, single words, or a generalization like pass/fail. Let's put complex ratings and reviews, like essays, aside for now.

Possible paths forward
  1. Have Wikidata properties for every sort of rating
    • Seems unlikely as there are endless rating systems and the majority are small datasets of <100 ratings
  2. Have some general property which we adapt with qualifiers
    • Perhaps we match this with identifiers, as many ratings are from data collections?
  3. Something else?

Thanks. More than anything, I wish for anyone to speak up if they remember or can point to any previous or ongoing conversation. Blue Rasberry (talk) 14:14, 29 August 2019 (UTC)

Hi Bluerasberry. I can give an overview of how things are done for video game (Q7889).

Need physician physicist

Can we merge deuteron (Q27459116) and deuteron (Q503527) ? Snipre (talk) 08:14, 28 August 2019 (UTC)

Physican here but a physicist would be more appropriate in this case ;-) Kpjas (talk) 08:35, 28 August 2019 (UTC)
@Snipre: I'm a physicist - though the properties on deuteron (Q27459116) look more like a chemistry point of view. But both items are about the same fundamental object, so it seems fine to me to merge them. ArthurPSmith (talk) 18:11, 28 August 2019 (UTC)

deuterium is an atom or isotope, yes. But the 1+ ion is missing its electron, so it's only the nucleus. ArthurPSmith (talk) 20:30, 28 August 2019 (UTC)

Missing items from WLM lists on itwikipedia

Hi, I am working with User:Giaccai on WLM lists for Tuscany and since one week we have been having problems with bizzare Listeriabot removal on itwikipedia. Some of these items were previously indexed but are not "seen" now by the system. For example this removal is where Piazza San Francesco (Q63982735) suddenly disappeared, few days ago it was only those items (that are still regularly removed if inserted). So it's hetting worse, apparently. Today we cannot insert almost anything from the civil parish of Vernio, at the bottom of the list example. We have similar situation in other local list but for some reason this is the worst one and it gives you a clear idea just in one place. I have however no clue why this happens so far, mostly because I have few time to analyze it. I hoped it would just naturally disappear...

The Italian community gave no resolutive answer by email so... any advice? It's not about local null edits or something like that. I also massively edits the items on various details just to be sure it could unblock something, it's not related to warning signs such as for example missing commons categories... One troubleshooting test I did not perform is to see if the problem is also on other wikipedias, I could do this as well but we are busy with hundreds of items to insert during these last days, i hope somebody can give me some advice before September, 1st. Otherwise the only temporary solution we have is to insert them manually every day to see them removed...--Alexmar983 (talk) 15:42, 30 August 2019 (UTC)

  • I think (Q63982735) disappeared as the item was merged the day before with another item that was already in the list. --- Jura 15:51, 30 August 2019 (UTC)
(Q66828154) is excluded from the query as P2186 has an end date. [24] --- Jura 16:02, 30 August 2019 (UTC)
but if the end date is this year, it should be excluded next year. i can try to put an end date and strat date together, it this is how is encoded.--Alexmar983 (talk) 16:04, 30 August 2019 (UTC) No let's try point in time.--Alexmar983 (talk) 16:07, 30 August 2019 (UTC)
ok now it works but I am not sure it's formally encoded correctly. For example if my WLM code is valid from year 2014 to 2019 (up to the end of the town council, as it could happen... I cannot encode it as "start date=2014, end date=2018", plus "point date=2019". it should be able to understand that end date implies the removal from the following year...--Alexmar983 (talk) 16:12, 30 August 2019 (UTC)
Maybe [25] or [26] works excludes the ones you are interested. The second query takes in account date precision. --- Jura 16:44, 30 August 2019 (UTC)
Don't worry, they are done manually to fix all minor details including external ID and commons category, so we know them quite well. we spot if a code is missing in the list. Thank you for the queries BTW, they might useful in other regions if they also refine this qualifier as we start to do (but still, this upper limit should not be encoded this way, when we say the last year we clearly include it).--Alexmar983 (talk) 17:16, 30 August 2019 (UTC)

Jura I still have doubts... I wish I had more times but WLM sucks a lot of energy with the social media campaign and reply to civil servants, I just try to do my best with some clear instruction and understand later. So if you have time to help me consider Calcinaia, I put "point in time 2019", as it should be and now it's gone. But I am quite it was not like that last year, I put "point in time" 2018 to at least one case, and they were listed. I might be tired but I feel something is different. You changed the code here right? They did modify something, maybe a comparison might show some clue. I am sorry i am just too full of stuff to process urgently to understand it right now. Thank you a lot.--Alexmar983 (talk) 17:58, 30 August 2019 (UTC)

  ?item wdt:P131* wd:Q16250 . 
  ?item wdt:P2186 ?wlmid .

  OPTIONAL { ?item p:P2186 / pqv:P585 [ wikibase:timeValue ?date ; wikibase:timePrecision ?dateprec ]  }

Try it!

Maybe the above helps. Seems I confused start time with point in time, but given the data, it didn't matter. If you know what dates you want to exclude (with or without a given precision), I can try to adjust the query. --- Jura 18:06, 30 August 2019 (UTC)

Automatically display lists of properties for Wikidata property items

For Wikidata property items like Wikidata property to link to Commons (Q18610173) (Wikidata property to link to Commons), it would be helpful to display a list of the corresponding properties like icon, image, Commons gallery, etc. on the Q18610173 page. The closest we have right now is the "What links here" link, but that's not limited to just the properties that are an instance of the property item, and it's not as easily accessible as including the list directly on the page.

Years of service for military person

I'm doing an integration of a local wiki "Infobox military person" with Wikidata, and there is a parameter "Years of service" which is a range of years, like "1879-1918". I was not able to find a property for that. Does anybody have an idea how can I define that in Wikidata? --StanProg (talk) 15:49, 28 August 2019 (UTC)

How to find a relevant property

Sometimes I need to find a matching property to express a relationship. For example, today, I wanted to connect the alligator Saturn (Q30600555) to Moscow Zoo (Q613676), where he is held, and I needed to figure out the appropriate property for that.

One way that might be helpful is the following SPARQL query:

It tells you which properties connect animals with zoos how often - and in the Query Helper UI it should be easy to change either types to figure out good candidates for the property you are looking for.

I thought this might be helpful to share.

Also, I recommend reading the article on Saturn (Q30600555) --Denny (talk) 16:53, 30 August 2019 (UTC)

@Denny: oh that will be very useful. Thanks! - PKM (talk) 19:08, 30 August 2019 (UTC)

Rock paintings into paintings with genre rock painting?

I would like to discuss the justification for a mass edit of cave painting (Q214334) into painting (Q3305213) with genre (P136) cave painting (Q214334). (Q11863834) one example. I wonder if it is a recommendation made in a project or just individual reasoning. In any case, I would like to oppose to this change, as it removes any hierarchies that cave painting (Q214334) could have that relate to archaeology, and promotes a visual arts perspective over others. @Nurni: – Susanna Ånäs (Susannaanas) (talk) 07:28, 29 August 2019 (UTC)

Provisionally AGREE with the above objections. seems arbitrary & limiting; could as easily be rationalised into a common group with rock-carvings into "cave art", with the property of being a painting :p & the archaeological considerations certainly apply! Lx 121 (talk) 08:30, 29 August 2019 (UTC)
Tried pinging the project Visual arts, but seems I cannot use the ping correctly. Sorry for the inconvenience, removed the blurb, but the respective members were probably pinged. – Susanna Ånäs (Susannaanas) (talk) 10:35, 29 August 2019 (UTC)
Agree - cave paintings are not, in the strictest sense, paintings as we refer to them in the d:Wikidata:Sum of all paintings project. Jane023 (talk) 12:57, 29 August 2019 (UTC)
As per this discussion I will revert those changes that I encounter in the set of items I am working with from the Finnish Heritage Agency (WLM for Finland). Thanks for your comments! – Susanna Ånäs (Susannaanas) (talk) 05:46, 31 August 2019 (UTC)
Consequently, the cave painting (Q214334) item needs revision, as its instance of (P31) is genre of painting (Q16743958). There is also a shift in the concept between the Finnish and English translations. The Finnish Wikipedia article and the source I added refer to paintings on rock surface while the English description and article refer to paintings on cave walls. I hope we can set up an alignment project for archaeological concepts! – Susanna Ånäs (Susannaanas) (talk) 06:17, 31 August 2019 (UTC)
@Susannaanas: I don't think I would call it a genre of painting. See Wikidata:WikiProject sum of all paintings/Top genres for often used genres. I made cave painting (Q214334) a sublcass of mural (Q219423) (which is a subclass of painting (Q3305213)). Multichill (talk) 14:56, 31 August 2019 (UTC)
Thanks, I think that should link it to painting. Perfect! – Susanna Ånäs (Susannaanas) (talk)

subclasses of physical quantity (Q107715)

I'm interested in an ontology of terms used in physical science. With it I found that the graph of subclasses of physical quantity (Q107715) contains a huge amount of objects which should not be subclasses of physical quantity, for example carnival (Q4618) should never be a physical quantity. Also the time measuring unit minute (Q7727) is not a physical quantity (it has a time interval but it should not be a subclass of "time interval"). Also events have time properties but they are never physical quantities. For more details about my concern see that discussion.

I've been wanting to translate the Wikipedia article on w:Julia Cagé from English into Spanish, but I want to use Wikicite for that.

  • Not sure I understand, but the template you linked is on en-wiki. You'd need to create an equivalent template on the relevant wiki. If you aren't at the relevant level in Spanish (or German) or even just with the citation mechanisms in those Wikipedias, you'd need to get someone with the relevant skills to do that, which I would think you are more likely to find on the relevant wiki than here. - Jmabel (talk) 17:49, 31 August 2019 (UTC)

Lac (resin), shellac, and lac dye

lac (Q15112450) and shellac (Q429659) seem to be confused.

Harlem Yacht Club confusion

Harlem Yacht Club (Q20642319) is a yacht club on City Island (disclosure: I'm a member). There is (was?) also a rap group named Harlem Yacht Club, which as far as I know has no wikidata entry. What's confusing is that WorldCat has an entry which somehow merged the two (as in, "which part of unique identifier did you not understand?"). What I'm trying to figure out is if there's something messed up in wikidata that's causing this, or if it's something WorldCat managed to mess up on their own. I'm guessing the later, but figured I'd start here. RoySmith (talk) 23:39, 29 August 2019 (UTC)

I don't see that Wikidata has ever had anything about the rap group - certainly not in the history of that item. LoC and other linked sites also seem to be about the club, not the rap group. Seems to be purely WorldCat confusion? ArthurPSmith (talk) 00:16, 30 August 2019 (UTC)

Bulk Loading of Entity URI

I am writing from the National Library Board Singapore. We have previously created a property National Library Board Singapore ID (P3988) to insert our name authority URI to existing Wikidata items. An example is the Wikidata item Catherine Lim (Catherine Lim (Q5052793)) which is inserted with the National Library Board Singapore ID We would like to bulk import our name authority URIs that match with the same Wikidata items. How do we proceed? (Nlbkos (talk) 02:57, 30 August 2019 (UTC))

Not clear what advice you need. Maybe quickstatements to enter data. Maybe a federated SPARQL query - presuming you can federate your RDF datastore and wikidata - to match candidates (e.g. based on VIAF, other common identifiers, or names and dates of birth)? You certainly don't need permission to proceed; the major questions are how & on what will you match items with your records. --Tagishsimon (talk) 03:10, 30 August 2019 (UTC)
Did you already match them with Wikidata items? If yes, you could use QuickStatements to upload the identifiers.
If you first need to match them, it depends on the other data or tool you have available/is available. Apparently P3988 is also in VIAF, so it might be possible to find the applicable items with that. --- Jura 03:12, 30 August 2019 (UTC)
@Nlbkos: can you describe what you want to do? With this query you can get the list of what is already matched. Do you already have matches or are you looking for a tool to make these matches? Multichill (talk) 13:13, 31 August 2019 (UTC)
@Nlbkos: As there are currently only 42 items in Wikidata with a value for P3988, I assume you wish to add further values to Wikidata. If you have already made the matches in your system, you can export them as a TSV (or speadsheet) file, then add the IDs to Wikidata using QuickStatements; if you have not, and need help with the matching, and to then add the matched values to Wikidata, you can use Mix'n'Match. Please let me know if you need help with either. it would also be good if you could display Wikidata IDs (and links) on your pages, like gzmyZ3wowyA.

Closed Airport Property

Kokura Airport (Q1930822) uses P582 to indicate the end time of the airport. Stapleton International Airport (Q1436575) uses P576, but P576 says to use P730 for buildings.

    significant event (P793) permits to have a very precise statement, here for example the end of use of an airport that is different from a destruction or even the start of construction of towers in the site of an airport. The main problem we can have is the lack of translations for these items (and because you are a chinese speaker, you have a big idea of this problem). In my opinion it is the biggest problem in Wikidata, by the past I propose we give a list of the 5000 more used items and more crucial to local Wikipédias, in the idea to obtain a minimum of translations, considering a minimum of items translated permits to offer a basis to future translators, but this proposal was systematicaly ignored. end time (P582) is a "wide" property, so we naturally use it when we must indicate an end. Not everybody know all specific properties, for example two days ago I discover date of official closure (P3999). Jérémy-Günther-Heinz Jähnick (talk) 08:51, 4 September 2019 (UTC)
