Counting uses of a property[edit]

What tool or query can I use to find how many items have a particular property? Is there (or should there be) a FAQ page with such info, and other simply query tips? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 23:13, 20 January 2016 (UTC)

@Pigsonthewing: Tabulated at Wikidata:Database reports/Constraint violations/All properties (though the report is a bit out of date).
The top of the constraint violation report (eg Wikidata:Database reports/Constraint violations/Pxxx for property Pxxx) gives a count which is usually pretty recent.
WDQ and SPARQL can also both produce counts fairly easily, eg if you want to add any specific conditions (eg counts for particular values of a particular property). Jheald (talk) 23:29, 20 January 2016 (UTC)
@Pigsonthewing: On the talk page of every property, the top-right corner of the {{Property documentation}} now displays various links, such as List of instances that shows counts & classes of items using that property. -- LaddΩ chat ;) 00:14, 21 January 2016 (UTC)
? Are you going to write a FAQ on this? --- Jura 05:11, 21 January 2016 (UTC)

Properties awaiting use[edit]

You could use Whatlinkshere to find if properties you proposed are still unused, sample(s):
--- Jura 07:14, 25 January 2016 (UTC)
vice-county (P1887) is not a special exceptions. On Wikidata:Database reports/List of properties/all you can list all properties sorted by the number of uses. There are in fact 256 properties which are used less than 3 times. --Pasleim (talk) 09:39, 25 January 2016 (UTC)
  • I had a looking into the various economics properties and had brought this up at Wikidata_talk:WikiProject_Economics#Sample_items.3F. While the same may apply to other properties with datatype quantity, it doesn't explain unused properties with other datatypes: e.g. string and item. I think it would be worth doing some stats on properties created more than a month ago and added to only five items or less:
  1. What is the property datatype?
  2. Who requested them?
  3. Is the requester still active?
  4. Who created them?
  5. Why aren't they being used?
  6. Why have they been requested?
All these properties create overhead and going through the property creation process isn't worth it when they aren't used. If they aren't used, it's not even clear what they may be used for. This may lead to the conclusion that we need to change the property creation process.
--- Jura 10:25, 25 January 2016 (UTC)

Jura is apparently still unhappy that his call to delete vice-county (P1887) garnered no support. Meanwhile this en.Wikipedia essay is pertinent. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 12:21, 31 January 2016 (UTC)

Unused property study[edit]

An additional factor to the ones mentioned above might be:

  • 7. How long did it take between the date the proposal was made and the property was created.

Possibly people loose interest when the delay is too long.
--- Jura 07:31, 5 February 2016 (UTC)

Wrecking (Soviet crime) is misleadingly linked to Politisch-ideologische_Diversion[edit]

I'm new to the project and would like to fix this language link.

The article for "Wrecking (Soviet crime)" describes a different phenomenon than the German one linked in "Languages" section. Russian and English articles describe the same phenomenon, but the German is something related but different.

How do I fix this?  – The preceding unsigned comment was added by Fungusakafungus (talk • contribs) at 14:07, 30 January 2016‎ (UTC).

Skin color property[edit]

Is there a skin color property in Wikidata to be assigned to instances of human (Q5)? --Jobu0101 (talk) 22:04, 30 January 2016 (UTC)

I hope such properties will never exist. --Succu (talk) 22:21, 30 January 2016 (UTC)
Why is that? By that logic properties for genders should not exist either. --Flukas (talk) 02:46, 31 January 2016 (UTC)
well, apart from rare cases (statistically speaking), gender is pretty objective ;)
skin color is not… and is certainly not a good way of classifying humans - it may change a lot in time (just getting sun-tanned may get you darker than many people considered as colored) and is racially prejudiced.
Race is not and (I hope) will never be a property on wikidata either… --Hsarrazin (talk) 09:49, 31 January 2016 (UTC)
As long as sex or gender (P21), sexual orientation (P91), ethnic group (P172) and religion (P140) properties exist, skin color property can be defined as well with the same restrictions. i.e. "reliable sources are required". Different cultures may have different opinions, but from database point of view it is just another property that can be obtained from reliable sources. But currently there is no such distinguish property. -- Vlsergey (talk) 09:50, 31 January 2016 (UTC)
Right some cultures are not really in line with what Wikipedia stands for. This is not a platform for a culture and having 'skin colour' is not excused by some culture, at most it is an excuse when it is YOUR culture. Thanks, GerardM (talk) 10:09, 31 January 2016 (UTC)
Would yo mind to move aside personal offensive and point out where exactly Wikidata rules or ideas prohibit any kind of property basing on European (ssuming) culture? Let me also remind you, that linking to image of any person is also prohibited by some cultures. Pointing out person ethnic group (P172) is also indecent in some cultures. Wikidata is not culture oriented in rules. Of course, in Wikidata (as long as i can see) rules in not everything. Too many solutions are made basing on personal or voting basis (and this is very sad). And because of that such rule will not exists in next few years (and this may be good IMHO). But not because of rules, but because of voting by Wikidata members. -- Vlsergey (talk) 10:23, 31 January 2016 (UTC)

@Succu: Such properties do already exists. See for example eye color (P1340) and hair color (P1884). In particular the latter one can also change. But that's no problem, we've got quantifiers which can tell a point in time or a timespan. --Jobu0101 (talk) 10:47, 31 January 2016 (UTC)

I think all information which can easily put into a database and is mentioned in Wikipedia should be (as a longtime goal) also represented in Wikidata. Skin color is such an information. Read for example the second sentence in the article en:Halle Berry:

She won an Academy Award for Best Actress in 2002 for her performance in the romantic drama Monster's Ball (2001), which made her the only woman of color to win a Best Actress Academy Award to date, as of 2016.

This sentence talks definitely about her skin color. So that's a relevant topic in Wikipedia and so should also be in Wikidata. --Jobu0101 (talk) 10:53, 31 January 2016 (UTC)

this sentence does not speak about her skin color, it is a polite way of telling she has african ancestors, therefore it's not a matter of color, but a racial identification :/
ethnic group (P172) is a controversial property, and I do not use it, myself…
instead of physically describing a person, putting a picture seems much better to me :) --Hsarrazin (talk) 10:58, 31 January 2016 (UTC)
PS : I think the only "objective" way to give skin color (without racial prejudice) would be to use a colour chart, which would not use words... but the variability of skin colour through the same year, just by sun action (and poor quality pictures) is too big to allow that ;) --Hsarrazin (talk) 11:02, 31 January 2016 (UTC)

@Hsarrazin: You're right. I was acutally not looking for a skin color property (you still might discuss this here and create it if you want). I was looking for a race property to which values like white, black, hispanic and so on are assigned. When you look at ethnic group (P172) you see that people assign countries there instead. --Jobu0101 (talk) 11:22, 31 January 2016 (UTC)

All that discussion is bullshit unless someone can propose an official and sourced system describing skin color or races. All other properties are well accepted because they are issued from offical identification systems provided by governements. Without that kind of caution any property will be a source of problem because everyone will do according to his point of view. Instead of losing time with that discussion start to find if you can source this kind of affirmation for a large number of humans having an element on WD. Just having a property for a small part of a elements class is useless from database point of view. Snipre (talk) 15:14, 31 January 2016 (UTC)
ethnic group (P172) is the best property to indicate a race, that gives a skin colour. Jérémy-Günther-Heinz Jähnick (talk) 16:22, 31 January 2016 (UTC)
Snipre I agree with you. Physical description on subjective and changing criteria is absurd :)
and racial description is prejudiced, since race is not scientifically proven. It's only been used to support discriminant policy.
as for ethnic group (P172) it is very controversed, being used to differentiate people from the same country on supposed different origins to justify battles that were based on language and/or culture... :( --Hsarrazin (talk) 16:42, 31 January 2016 (UTC)

Hoi, many people in India are much darker than many people in or from Africa. The notion that colour has anything to say with race is a fallacy. Thanks, GerardM (talk) 18:34, 31 January 2016 (UTC)

Not sure that skin color property is useful for real people. Many people change skin tint each half year because of sun exposure. However it could be useful for paintings. That's another example, when color of skin has nothing to say with race. --Lockal (talk) 21:11, 5 February 2016 (UTC)

Use color (P462) qualified by applies to part (P518) = skin (Q1074). --Succu (talk) 21:42, 5 February 2016 (UTC)

Can't find a Wikidata entry[edit]

Hi I have previously made edits to a wikidata entity for luiz ildefonso simões lopes. I can't seem to find this entry any more, Could someone please help me locate it. Thanks  – The preceding unsigned comment was added by 5.62.12.166 (talk • contribs) at 14:53, 31 January 2016‎ (UTC).

I can't find it too and I also can't find any (deleted) contributions on this IP adress. Makes it difficult to find it. Sjoerd de Bruin (talk) 14:55, 31 January 2016 (UTC)
Good match: Ildefonso Simões Lopes (Q10301036). Did you look for this one? —MisterSynergy (talk) 14:59, 31 January 2016 (UTC) :Another idea: pt:Luiz Ildefonso Simões Lopes was recently deleted at ptwiki due to lack of notability. Maybe the corresponding Wikidata item was deleted as well?! —MisterSynergy (talk) 15:03, 31 January 2016 (UTC)

Thanks for trying to help. The first one Ildefonso Simões Lopes (Q10301036) is a different person. pt:Luiz Ildefonso Simões Lopes is the right person. Would a wikidata entry be deleted automatically if the wikipedia page was deleted?  – The preceding unsigned comment was added by 5.62.12.166 (talk • contribs) at 15:14, 31 January 2016‎ (UTC).

Depends on the notability status. Sjoerd de Bruin (talk) 17:13, 31 January 2016 (UTC)
It will not be deleted automatically, but if it lacks notability at any Wikipedia, it probably isn’t notable at Wikidata as well. Cf. Wikidata:Notability for details. —MisterSynergy (talk) 17:17, 31 January 2016 (UTC)
here, I would disagree. You could have enough info for a wikidata item, without having enough for an article on wp. And some wp are very hard on stubs :/ --Hsarrazin (talk) 17:38, 31 January 2016 (UTC)
Would be great if we could find the item that was deleted, so we can see what statements it contained. Sjoerd de Bruin (talk) 08:33, 1 February 2016 (UTC)
I managed to find Q21803286, I don't see a link to the Portuguese page in the history though, so I don't know if it was just never linked or if there was another item. - Nikki (talk) 15:56, 1 February 2016 (UTC)

Examples of Wikidata in use[edit]

I'm looking for examples of data from Wikidata in use, to include in some upcoming talks. Ideally, they will be "real world" uses, but demonstrators will also help. We don't seem to have a page listing such things (or have I missed it?).

So far, I have:

Can anyone suggest others, or point to an existing list, please? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 17:00, 31 January 2016 (UTC)

I would suggest the beautiful Crotos project, that I often point out to show what's possible :) --Hsarrazin (talk) 17:20, 31 January 2016 (UTC)
@Pigsonthewing: Module:Cycling race, that is able to work on 14 Wikipedias, and that permit to display a table for stages and another for the palmares of a race, it is the fruit of a collaboration between the user Molarus for the code and me for tests and contacting users. A common infobox is currently in development, and we have start a common documentation that will can be translated by users. It works, I can get you more examples if you want. Jérémy-Günther-Heinz Jähnick (talk) 17:29, 31 January 2016 (UTC)

Thanks, all. How could I forget Histropedia! I've made a page at Wikidata:Examples, but please keep them coming. J-G-H, examples of that module in use would be good, please. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:20, 31 January 2016 (UTC)

  • For example, the infobox in fr:Tour de France 2015 uses fr:Module:Infobox/Descriptif course cycliste a Lua module, written by fr:Utilisateur:Zolo.
  • But Wikidata is used most of the time in infoboxes which are build with templates. This is the job of Module Wikidata (see Q12069631 which Wiki has this module).
  • A good example of Module:Cycling race is maybe the table "Palmarès" in fr:Tour de Norvège (2011) and another table in mk:Тур Даун Андер 2016 and ja:ツール・ド・フランス2016. For the infobox we will have to work some weeks, but you can already take some screenshots. Our infobox will have new features, you have never seen before.
  • About SPARQL: I don´t know if this is an examples of Wikidata in use. I used the SPARQL-Endpoint in a javascript tool (User:Molarus/SPARQL-Endpoint-01.js) to find Wikipedia articles about lakes in DE, CH and AT where I read data from infoboxes which I moved to Wikidata. I did this for the property P2044 (elevation above sea level). Maybe a similar task is possible with the tool autolist 2 from User:Magnus Manske. I have never done that, ask him if you want to know.
  • Another use of SPARQL could you see at Property_talk:P625. There are two SPARQL queries at "Lists": The first query lists globe parameters and the second query lists items with a wrong globe parameter. --> SPARQL is used for maintenance work within Wikidata.
  • A nice example is maybe [1], but I don´t speak french.

--Molarus 01:28, 1 February 2016 (UTC)

Suggestion I would recommend making a page like Wikidata:Applications that list these. —Justin (koavf)TCM 04:25, 1 February 2016 (UTC)

Wikiversity getting language links via Wikidata soon[edit]

Hey everyone :)

Just a quick heads-up that Wikiversity will get its language links via Wikidata on 23rd of February. Coordination is happening at Wikidata:Wikiversity. --Lydia Pintscher (WMDE) (talk) 16:09, 1 February 2016 (UTC)

Probably some bug in mass message - thgere was 23rd January [3]

upcoming deployments/features[edit]

Hey folks :)

I just sat down with Katie to plan the next important feature deployments that are coming up this month. Here is the plan:

  • new datatype for mathematical expressions: We'll get it live on test.wikidata.org tomorrow and then bring it to wikidata.org on the 9th
  • Article Placeholder: We'll get it to test.wikipedia.org on the 9th
  • new datatype for identifiers: we'll bring it to wikidata.org on the 16th. We'll convert existing properties according to the list on User:Addshore/Identifiers in two rounds on 17th and 18th.
  • In Other Projects Sidebar: We'll enable it by default on 16th for all projects that do not opt-out on phabricator:T103102.
  • interwiki links via Wikidata for Wikiversity: We'll enable phase 1 on Wikiversity on the 23rd.

Cheers --Lydia Pintscher (WMDE) (talk) 16:14, 1 February 2016 (UTC)

Exciting news! Looking forward to it.
--- Jura 16:34, 1 February 2016 (UTC)
@Lydia Pintscher (WMDE): I still have concerns about the accuracy of that list of identifiers. Where the points raised in the previous discussion addressed? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 18:59, 1 February 2016 (UTC)
Please feel free to change the list until the 17th. I'll take what is there at that point. I don't want to impose too much from my side. --Lydia Pintscher (WMDE) (talk) 19:13, 1 February 2016 (UTC)
Alas, I lack both the tools and the time to make the necessary checks and fixes. Nut I have suggested to the best of my ability some measures that I hope may help others to so so. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:33, 1 February 2016 (UTC)
Lydia, is there some place to interact with the developers working on the identifiers? I really don't know how to judge whether proposed properties meet the criteria or not right now. Also as Andy indicates, it would be REALLY helpful to have a lot more eyes looking at the lists that have been generated! ArthurPSmith (talk) 20:10, 1 February 2016 (UTC)
Feel free to ask questions here. I'm reading it and will answer them as best as I can. Would it help to introduce some way to mark the things someone already went through as checked? --Lydia Pintscher (WMDE) (talk) 20:14, 1 February 2016 (UTC)
I guess, beyond being a string datatype, what are the key criteria for an "identifier"? Does given name (P735) qualify (I assume not) but if not why not? I was left very confused after the discussion on Addshore's talk page. ArthurPSmith (talk) 22:08, 1 February 2016 (UTC)
For me the criteria is something like "it helps us look up the same concept in some other database/website/etc". I'd say given name does not qualify. --Lydia Pintscher (WMDE) (talk) 08:43, 2 February 2016 (UTC)
I think of identifiers as something which (more or less) uniquely identifies something. A given name does not belong to a particular person, it can be used by anyone anywhere (as long as it's allowed by local naming laws). That approach also implies to me that an identifier has some website or organisation behind it which either assigns the identifier itself (e.g. Wikidata assigns an ID to an item on creation) or decides whether an identifier chosen by a user is acceptable (e.g. a user picks a username on a site and it does not allow them to choose one which is already in use). - Nikki (talk) 10:02, 2 February 2016 (UTC)
Hi all! Per request by 2 people I have created User:Addshore/Strings which contains all properties that are of string type that are not currently listed on the Identifiers pages in my user page! Enjoy! ·addshore· talk to me! 11:14, 2 February 2016 (UTC)
Will there be a possibility to later change the datatype of either properties we forgot to list or revert properties back to string if we figure out that the identifier type was not correct? --Srittau (talk) 12:44, 2 February 2016 (UTC)
We can convert more later. Though I'd prefer to keep the disruption minimal to 3rd parties and rather do as many as we can in one round. From identifier back to string I am not sure but I will ask. --Lydia Pintscher (WMDE) (talk) 12:49, 2 February 2016 (UTC)
What should we do if we think something which has been added to the list of identifiers is not actually an identifier? - Nikki (talk) 13:15, 2 February 2016 (UTC)
Would it work for you to move it to a "disputed" section? --Lydia Pintscher (WMDE) (talk) 13:17, 2 February 2016 (UTC)
Maybe adding a short note about why it meets or doesn't meet the criteria mentioned on the talk page would help.
--- Jura 14:03, 2 February 2016 (UTC)
I object to any properties in this list being converted. Probably only properties which are instance of Wikidata property representing a unique identifier (Q19847637) or subclasses should be converted. All other properties should be looked at before thinking about converting. Multichill (talk) 22:49, 2 February 2016 (UTC)
Please join the discussion on the talk page about the criteria to be used. Merely objecting isn't going to help.
--- Jura 22:52, 2 February 2016 (UTC)
I have now added sections to the pages so that we can sort identifiers into them more easily. I'll start with doing some for the first page now. I hope this helps. --Lydia Pintscher (WMDE) (talk) 11:22, 3 February 2016 (UTC)
Could you also complete the list of characteristics? Not much use to attempt to sort if we don't agree on those.
--- Jura 11:27, 3 February 2016 (UTC)
The list is good from my side. Let's move the things we intuitively agree on and then see what's left? --Lydia Pintscher (WMDE) (talk) 11:31, 3 February 2016 (UTC)
I think if we're going to sort through the lists again to pick out things which we think are definitely identifiers, it should be done based on objective criteria. Deciding intuitively is how the current lists were created, so doing the same thing again would be silly. The current characteristics list doesn't help either as it's currently written because "is a string" is the only thing which is not optional (also, some of the examples are things Multichill already objected to). I would suggest that strings which are unique values created by a single issuer (following a consistent pattern) and assigned to a single thing can definitely be considered identifiers, if people agree, we could move all of those to the "good to convert" section and then look at the ones which are left. - Nikki (talk) 16:38, 3 February 2016 (UTC)
I agree with Nikki, the criteria currently listed are not useful as they boil down to only "it is a string", which makes the distinction between string and identifier properties worthless. I don't know where "license plate number" came up as an example of an identifier, but I believe it should NOT be considered, for the same reasons Multichill gives. ArthurPSmith (talk) 16:59, 3 February 2016 (UTC)
FYI I converted many of the 'may' criteria to 'must's in the list on User:Addshore/Identifiers based on Nikki's summary statement above. ArthurPSmith (talk) 17:05, 3 February 2016 (UTC)
Could you just annotate them with the reference you have for your criteria?
--- Jura 17:10, 3 February 2016 (UTC)
The reference is this discussion. I have annotated. ArthurPSmith (talk) 18:31, 3 February 2016 (UTC)
Not sure if Nikki meant to say that ISBN is not an external identifier. Anyways, I referenced earlier discussions on commented on your criteria.
--- Jura 04:31, 4 February 2016 (UTC)
I think it's a good idea to state the criteria. I added a few samples to the characteristics. Please add more.
--- Jura 11:52, 3 February 2016 (UTC)
  • Maybe a question to ask for the definition of external identifiers is if we should bear in mind only wikidata.org or possible installations outside Wikimedia. Currently some seem to be focusing on identifiers such as VIAF which are of global interest. For a local installation of Wikibase covering, e.g. only the United Kingdom, MNC (e.g.) might simply be mapped to a uk domain. If we exclude these from external identifiers, the features associated with external identifiers can't be used on such sites.
    --- Jura 05:29, 4 February 2016 (UTC)
    • Wikidata.org decides for itself what external identifiers are. Local installations have their own properties and their own property definitions. We are switching some of our properties to another datatype. Local installations can use different datatypes for properties we use, for instance, they might store the IMDb id as a URL in a URL datatype property. I don't think it's hardcoded that any installation of Wikidata must have VIAF id as an identifier datatype property (if we decide for it to be a indentifier datatype property). Mbch331 (talk) 13:23, 4 February 2016 (UTC)
      • The idea is that they would supplement their information with a subset of Wikidata.org data. Obviously, if the installation is empty, anything can be done, but I doubt you could import Wikidata.org data into properties with another datatype.

Dispute resolution re legislatures[edit]

On pages about cities in the Philippines, such as Naga (Q316197), I removed legislative body (P194) -> city council of a Philippines city (Q7417960) because city council of a Philippines city (Q7417960) is the type of legislature and not the name of each city's legislature proper. The property restrictions on legislative body (P194) says that it usually has a unique value, suggesting that it was intended to link to classes of legislature. My edits were undone a couple times by User:194.75.238.182. Can someone please moderate this before I get into an edit war? Thanks. --Arctic.gnome (talk) 17:34, 1 February 2016 (UTC)

Adding area in square km to an item[edit]

Hi

Is it possible to add a value for an area in square km to an item? I would like to do it for some protected areas in the UK. I'm not sure if I just can't find the right Q number or its not available (or Im doing something wrong)

Properties for museum collections?[edit]

Hi,

I'm looking for properties that links to museum collections (ID's). I wonder how many such properties we have on Wikidata, what is the easiest way to find them all? Searching "Museum" gave some results, but maybe there are more. --Stryn (talk) 18:19, 2 February 2016 (UTC)

And an additional question: If a museum has ID's for every items that are in their collections, and those have a separate page on their website (where they can tell a little bit about items), does it make sense to add those ID's to Wikidata? --Stryn (talk) 18:38, 2 February 2016 (UTC)

While "related properties" tool is broken, you could use this sparql query. This query also returns generic properties, but identifier properties are clearly distinguishable. And yes, it makes sense to add these identifiers to Wikidata. --Lockal (talk) 18:47, 2 February 2016 (UTC)
@Stryn: The properties should all be in this list. We generally use inventory number (P217) and described at URL (P973) on works, not need to have a dedicated property explosion. Multichill (talk) 22:26, 2 February 2016 (UTC)
Thank you both. I see we don't have any properties for "game museums". Maybe Videogame History Museum's Online Videogame Database could be proposed. --Stryn (talk) 16:00, 3 February 2016 (UTC)

last call for feedback on showcase item process[edit]

Hey folks :)

High-quality content and showcases are important for Wikidata. The showcase item process hasn't really worked though. A while ago Harmonia Amanda and Sjoerddebruin have been working on improving it. Please give you final input at User:Harmonia Amanda/Showcase items and the talk page there so we can move this forward. --Lydia Pintscher (WMDE) (talk) 11:58, 3 February 2016 (UTC)

Should these be merged?[edit]

Q22340956 and Q7234364. One was originally a list in Wikipedia but I changed the Wikipedia list into a position article, so now they are identical. --Richard Arthur Norton (1958- ) (talk) 15:27, 3 February 2016 (UTC)

Ah yes, I think the list can be deleted. Merging will cause only mess. Sjoerd de Bruin (talk) 16:54, 3 February 2016 (UTC)

Wikidata w/ external Wikiba.se projects?[edit]

Hello all -- I was wondering if anyone had any experience with incorporating Wikidata with other Wikiba.se projects or could point to successful integrations. Several research projects I'm affiliated with would benefit from the Wiki-style databases, which makes Wikiba.se a logical platform, but also connecting with the data and especially the property types, unit types, of Wikidata. Obviously, if everything in the project were Wikidata-compatible statements then the obvious choice would be simply to contribute to Wikidata, but some of the database information would include expert opinions, not facts, and links to copyrighted/non-free images and music files. So a system that could store its own data but link to and query (and potentially contribute back to) Wikidata would be the ideal. Has anything of this sort been done? Best, Mscuthbert (talk) 19:07, 3 February 2016 (UTC)

While this isn't possible yet, we definitely want something like that in the future. Wikidata should serve as a central place to provide identifiers for real-world objects. Especially for Wikimedia Commons we will need that feature if that wiki also becomes a data repository. One issue that isn't solved yet is how to propagate updates made within Wikidata to other clients that don't have direct database access. Best regards -- Bene* talk 08:09, 4 February 2016 (UTC)

Save button deactivated?[edit]

I try to add descriptions to Q371733, but when I click "edit" the "save" button stays deactivated... --Gereon K. (talk) 12:49, 4 February 2016 (UTC)

No. Both items have a valid sitelink to enwiki. They first need to be merged on enwiki. Request it there. When the merge there has been done, they can be merged. Mbch331 (talk) 17:23, 4 February 2016 (UTC)

What are identifiers?[edit]

Please have a look at User:Addshore/Identifiers, a pretty important discussion about "what is an identifier" is going on over there. (Spun off from the discussion above.)

"save" button disabled[edit]

Yesterday noticed that any "save" button is disabled (inactive grey color). First I thought of some page protection but I see it's the same for any Q page. Page reload/purge didn't help. Is this some limitation on me or do I need to look for a tech problem on my side (any hind would be appreciated then). --NeoLexx (talk) 18:41, 4 February 2016 (UTC) UA - Chrome 48.0.2564.97 m

Oops, sorry, just saw Save button deactivated? higher, reading... --NeoLexx (talk) 18:44, 4 February 2016 (UTC)

  • Noop. I updated my Chrome (now 48.0.2564.103 m) and restarted Win10 - still disabled grey. So whatever the fix was at #Save button deactivated? it didn't make the trick for me. --NeoLexx (talk) 18:50, 4 February 2016 (UTC)
@Neolexx: You might want to retry now and if it still doesn't work clear your cache. The problem should be fixed, but due to caching in your browser you might still run into it. - Hoo man (talk) 10:08, 5 February 2016 (UTC)
@Hoo man: I cleared the Chrome completely (More Tools > Clear browsing data) w/o any effect. I also tried from IE11 which I didn't use for browsing at all (only for local script testing) and it is still grey disabled "save" button, say here https://www.wikidata.org/wiki/Q3371867 Is there anything else I or we need to look at? --5.18.228.61 10:20, 6 February 2016 (UTC)
Did you follow the steps exactly? The save button is only supposed to get blue once something actually changes. If you can still reproduce the problem, can you tell me if you see any JavaScript errors in your browser's error console (accessible probably by pressing F12, but that's browser dependent). You might also want to try appending ?debug=true to the URL and see whether it still happens then. Cheers, Hoo man (talk) 00:26, 7 February 2016 (UTC)
@Hoo man: It started to work again a few hours ago. Thank you, but do you know the exact reason of the glitch like this or at "Save button deactivated?" topic earlier? Clearing the cache of the mainly used browser is a rather big inconvenience (browser history, address prompts etc.) If there is a particular problem a more narrow fix might be found. --NeoLexx (talk) 04:05, 7 February 2016 (UTC)

Accents[edit]

I'm working on the KasparBot project to migrate Persondata to Wikidata, and I have a question about aliases. Should I migrate aliases that are the same as the title, but without accents?

For example, this challenge on Lukáš Cikánek: should I add the alias "Lukas Cikanek"?

StephenWade (talk) 18:52, 4 February 2016 (UTC)

I usually will if the accentless version is mostly aliasing a good chunk of accents and those accents are in the first name. Lukas Cikanek is a good one to alias without accents. However, a Gregory Proporvi`tch isn't IMO because autocomplete will take care of getting you to the right one. Just my thoughts; I'm not sure we have any guidelines on the point. Help:Aliases says it's fine to do so either way, I think. --Izno (talk) 21:41, 4 February 2016 (UTC)
I usually accept the version without diacritics. Bowever, I would like it better, if the tool would ignore or separate those (like "aliases, only differing in the absence diacritics" and "aliases, rest". It's a bit tedious to accept hundreds of thousands of those manually (and, given the natute of the tool, compared to e.g. The Game, which preloads the nexts items while editing, ar a comparatively low pace), while that particular aspect of the task could be done much easier by a bit. If we want diacritic-free aliases for people's names (and other things) in English, a bot could create them automatically and for all at once, not just the small subset of them where enwiki persondata happen to have such a version). Similar cases are aliases that just are the surname of somone, and Asian names in the form forename surname where the natural form is the other way round. (Pinging User:T.seppelt, whom I'd like to thank for his efforts, by the way). --YMS (talk) 16:08, 6 February 2016 (UTC)
There's a ticket for ignoring accents at phab:T121863. - Nikki (talk) 19:11, 6 February 2016 (UTC)
That only helps if you type the beginning of the name manually. It doesn't help if you search for something by pasting the name (something I do a lot). It probably doesn't help many external tools/bots since they're likely to search for the whole name too. - Nikki (talk) 19:11, 6 February 2016 (UTC)
Help:Aliases says to add unaccented versions, so I don't see why not. They can always be removed later if the search is improved and we decide we don't want them any more. - Nikki (talk) 19:11, 6 February 2016 (UTC)

I could add all aliases from the persondata data set which are just accent-free versions of already existing labels or aliases automatically using my bot. What do you think about it?--T.seppelt (talk) 19:16, 6 February 2016 (UTC)

Linking OSM and Wikidata for World Heritage, Man and the Biosphere and Global Geopark items[edit]

Hi all

I work at UNESCO as their Wikimedian in Residence, I'm currently importing data about UNESCO inscriptions (e.g World Heritage Sites) to Wikidata through Mix n' Match. I would very much like to create a link between Wikidata and OpenStreetMap for each of the physical place inscription programmes (World Heritage, Man and the Biosphere and Global Geoparks). Here is a plan of how I think this could be done, I would very much like some feedback on the possible approach and if anyone would be interested in joining in please let me know.

  1. Import all World Heritage, Man and the Biosphere and Global Geoparks items into Wikidata, currently only the World Heritage Sites are complete but the other sites are being imported soon.
  2. Create a page to organise the importing, we can create a section on https://meta.wikimedia.org/wiki/WikiProject_UNESCO
  3. Create lists for showing which of the sites for each programme do not have the link to OSM. For instance here are all the World Heritage sites with no OpenStreetMap Relation identifier This will act as a work list to know what work has and hasn't been done.
  4. Propose identifiers on OSM for Man and the Biosphere sites and Global Geoparks in the same vein as World Heritage Sites https://wiki.openstreetmap.org/wiki/Key:heritage
  5. Find all the existing OSM objects for the sites and add the identifier and link them to Wikidata.
  6. Create any new objects that don't currently exist on OSM, add the key identifiers and add the identifiers to Wikidata.

I hope that we could involve people from both the Wikidata and OSM communities (I assume there is some overlap anyway) and encourage more people interested in Wikidata to learn about and contribute to OSM and vice versa.

I've also posted this message on the OSM forum (currently waiting for moderator approval, will update with link)

Thanks

How does Wikidata handle dates for when items were inscribed onto official lists[edit]

Hi

Is there a way of adding an inscription date for when items were added to lists? E.g a year for when a place became a World Heritage site.

Thanks

John Cummings (talk) 11:22, 5 February 2016 (UTC)

You can use point in time (P585) as a qualifier. Mbch331 (talk) 12:23, 5 February 2016 (UTC)
Thanks @Mbch331: :) I guess the other option is use start time (P580)? John Cummings (talk) 12:27, 5 February 2016 (UTC)
That depends if an item can lose it's status as a World Heritage site. If it can lose the status, then P580 is the best option, if it's expected never to lose the status than P585 is a better option. As P580 implies that one day end time (P582) will follow. Mbch331 (talk) 12:33, 5 February 2016 (UTC)
I don't think I agree with that statement. Point in time qualifier indicates that it was a heritage site for a single year, which is incorrect. See statement of domain on the talk page: "Anything that was confined to a specific time, but not a range of time". --Izno (talk) 12:45, 5 February 2016 (UTC)
@Mbch331: Yes sites can be delisted e.g Dresden, so it would need to be for a time range rather than a specific year. Does this mean start time (P580) and where needed end time (P582) should be used? John Cummings (talk) 15:13, 5 February 2016 (UTC)
Yes indeed. P580 and P582 are the properties to use. Mbch331 (talk) 17:12, 5 February 2016 (UTC)

Wikidata data imports mailing list[edit]

I've put a request on Phabricator for the creation of a Wikimedia mailing list for people interested in importing data into Wikidata from external data sets.

John, I'm sure more interaction about importing data to Wikidata will be useful, but can you please elaborate why you're not just setting a space up here at this wiki? Multichill (talk) 17:27, 5 February 2016 (UTC)

@Multichill:, I'd also like to set up a place on here too, maybe called something like 'Data import chat'. I think some people (myself included) prefer the discussion over email rather than on wiki, I find it a lot easier to filter stuff I'm not interested in and also to forward conversations to people I think may be able to help. I assume this is why the Wikimedia public mailing lists exist too. I'm working on some pages 1, 2 for data importing as well that hopefully should kind of work along side the on wiki and mailing list discussions to answer a lot of the basic questions.

How do I indicate that someone gave a lecture[edit]

There are named lectures that are given as a celebration or an award. How best to indicate that someone presented such a lecture? Thanks, GerardM (talk) 10:55, 6 February 2016 (UTC)

For the numbers of works that I have reproduced for Wikisource, I I have used "public address" as the instance, and then used the property "speaker" for the person. Other components added have been a "point in time" as a qualifier for instance, added a location, and if part of series of lectures linked to that. As I am working on the published version, that gets linked as through "editions(s). I will try and find a reasonable example.  — billinghurst sDrewth 22:39, 6 February 2016 (UTC)

Promoting in results list for instance of (P31)?[edit]

When adding instance and typing the full word "edition" edition (Q3331189) this identifier is not appearing in either the top 5, or the top 10.

What can be done to promote this property in the results list?  — billinghurst sDrewth 22:35, 6 February 2016 (UTC) (UTC)

  2. If the linked category was moved to another item -> merge with the other item
  3. If the linked category doesn't have a wikidata item -> restore the sitelink

Tool for finding duplicates among disambiguation pages?[edit]

Is there a tool that can identify duplicates among disambiguation pages Wikimedia disambiguation page (Q4167410)? I have a feeling that there might be a lot of duplicates. //Mippzon (talk) 12:43, 7 February 2016 (UTC)

@Mippzon: You could define, what is duplicate in your case. Sitelinks/labels? I think there would also be a lot (too much) of false positives, but you can try, of course :) Pasleim most probably can generate a list for you. --Edgars2007 (talk) 17:36, 7 February 2016 (UTC)
@Edgars2007: Sorry, I was probably a bit vague in my question :) What I mean is if there is a tool or similar for finding items that could be merged with each other when it comes to Wikimedia disambiguation page (Q4167410)? When running Duplicity for items on svwiki (which currently includes a lot of disambiguation items not linked to Wikidata) it often found multiple disambiguation items in the search results. I could then merge them and add the svwiki item to the merged one. I guess this is not the best way of finding those problems though :) //Mippzon (talk) 18:22, 7 February 2016 (UTC)
This could be a good start: tinyurl.com/jx44fgr. Matěj Suchánek (talk) 19:52, 7 February 2016 (UTC)
Please be cautious while merging, as often there is a situation, when in one item disambiguation and non-disambiguation links are mixed. In this case merging another disambiguation item will cause even more mess. --Jklamo (talk) 00:16, 8 February 2016 (UTC)

Link the query service more prominently[edit]

Hey folks :)

I think it is time to give the query service a bit more exposure. I encounter quite a few people who are still surprised that we have a SPARQL endpoint. It is such a central piece of our puzzle. I had asked here a while ago already but got no replies: https://www.wikidata.org/wiki/Wikidata_talk:Main_Page#Link_to_query_service.3F Please chime in there. Thanks! --Lydia Pintscher (WMDE) (talk) 17:30, 7 February 2016 (UTC)

I added a "start a query" link to property talk pages. Maybe we could put it directly on property pages.
--- Jura 17:42, 7 February 2016 (UTC)
Jura proposed a property for this; currently opposed by one and a comment or two. My inclination is that this should be probably be in Wikibase on the property page. --Izno (talk) 18:17, 7 February 2016 (UTC)
This is something else. Visit a property talk page.
--- Jura 18:20, 7 February 2016 (UTC)
Hmm? No, I think it's exactly the same thing. Lydia is looking to increase the visibility of the SPARQL endpoint, an end also reached by adding it to the property pages. --Izno (talk) 18:23, 7 February 2016 (UTC)
I think it's worth trying one of the "start a query"-links. A new property could store statements with urls of specific queries, while the current "start a query" link on property talk pages is just a generic query using that property. A similar link could be on any property page without actually requiring to be defined in a statement.
--- Jura 18:48, 7 February 2016 (UTC)
Maybe add a more technical section to the user portal, including the query service? Sjoerd de Bruin (talk) 18:29, 7 February 2016 (UTC)

Property for applicable dates[edit]

Let's consider the following data for «heritors»:

What properties shall be used to store such dates? -- VlSergey (трёп) 09:59, 8 February 2016 (UTC)

inception (P571) and dissolved or abolished (P576). --Yair rand (talk) 10:16, 8 February 2016 (UTC)
@Yair rand: those properties is not a good choice. It is questionable whether inception (P571) can be used to store such information (because infobox of Russia (Q159) displays not 1991 year but 862 year (and it does make sense). Also use of dissolved or abolished (P576) for Russian Soviet Federative Socialist Republic (Q2184) would be incorrect. It was not dissolved nether abolished, it was renamed to Russia (Q159). -- VlSergey (трёп) 10:50, 8 February 2016 (UTC)
P.S.: in practice, i would agree with any kind of solution, and personally P571 / P576 sounds good enough for me. But I would like to have consensus on such decision to be able to also put, for example,
< East Germany (Q16957) (View with Reasonator) > dissolved or abolished (P576) miga < 3 October 1990 >
,
< Latvia (Q211) (View with Reasonator) > inception (P571) miga < 4 May 1990 >
, etc. Please, consider such complex example:
i.e. please notice that we have 2 different P571 for Latvia (Q211). -- VlSergey (трёп) 11:10, 8 February 2016 (UTC)
Another solution could be in Q211 (Latvia)
  • P571 (inception) 29 March 1917
  • P571 4 May 1990
  • P156 (followed by) Q192180 (Latvian Soviet Socialist Republic) Qualifier P585 (point of time) July 1940.
And in LSSR:
  • P571 July 1940
  • P156 Q211 (Latvia) P585 4 May 1990. --Molarus 11:50, 8 February 2016 (UTC)

Racing/racecar drivers[edit]

Hi Wikidata. I'm currently trying to help out with importing data from the Persondata templates in the English Wikipedia via KasparBot. My main area of activity is racing driver articles. I have a couple of questions:

  • I notice that both "racecar driver" and "racing driver" are currently used on Wikidata (a search for "racecar driver" returns 1627 hits; a search for "racing driver" returns 5092 hits). Would it make sense to standardise on one form or the other? (I recognise that American English typically uses "racecar driver" whereas British English typically uses "racing driver").
  • Help:Description identifies the common formula for the description of a person as "[career the person is known for][country]", e.g. "racing driver from Sweden". However the vast majority of racing driver entries I've encountered so far use the form "[country][career]", e.g. "Swedish racing driver" (which is the format typically used within the Persondata templates in English Wikipedia). Is the "[career][country]" format greatly preferred over the "[country][career]" format?

Apologies if these issues have already been discussed, but I couldn't find anything in the chat archives and there doesn't seem to be a motorsport WikiProject. Thanks in advance. DH85868993 (talk) 10:31, 8 February 2016 (UTC)
