Taxonomy Browser

Taxonomy Browser seems to be dead.--Jklamo (talk) 08:03, 7 September 2017 (UTC)

Can we add SQID?

Can we add https://tools.wmflabs.org/sqid/#/ ? It seems to be a much better tool for working and examining classes than the existing tools linked. Sadads (talk) 17:02, 30 October 2017 (UTC)

I'm not a big fan of squid which is really really slow in my experience. I would consider removing it. PAC2 (talk) 22:22, 23 February 2021 (UTC)

This templates causes errors on over 1000 pages

It seems like some changes in this template or templates it uses is causing errors in over 1000 pages, which are then added to Category:Pages with script errors. Can someone fix that issue, otherwise we might have to remove it from those pages. See for example Talk:Q1000003. --Jarekt (talk) 19:03, 18 May 2019 (UTC)

Problem is in {{Is a}} when the result should be false. --Infovarius (talk) 23:52, 21 May 2019 (UTC)

Fixed with this diff to replace the function with a Module:PropertyPath one. Also needed a bugfix on this last module to handle a missing « unknown value Help » case, it seems that there is a few classes with « some value » as a parent class. Maybe someone used this to « fix » a constraint that a class must have a parent class (probably not a good idea) ? @Jarekt, Infovarius: author  TomT0m / talk page 08:02, 22 May 2019 (UTC)

@TomT0m, Infovarius: Thanks a lot for looking into it. --Jarekt (talk) 12:19, 22 May 2019 (UTC)

More errors in Category:Pages with script errors

More errors in Category:Pages with script errors, see:

• Talk:Q4022
• Talk:Q44377
• Talk:Q47521
• Talk:Q63819493
• Talk:Q79007

Any idea how to fix them? Or shell we just remove {{Item documentation}} them from those pages? --Jarekt (talk) 18:56, 1 July 2019 (UTC)

@jarekt: « not enough memory » could mean some items in the class tree became too big and are loaded by the template that shows the class tree. If it’s this it will be enough to replace the code that load the full item with the api call that just retrieve the subclass of (P279) statement, I will investigate. author  TomT0m / talk page 19:09, 1 July 2019 (UTC)

It seems someone, an IP, for some reason decided a few hours ago to add statements about some physical objects being special cases of mathematical objects resulting in a blow up of the parent class tree. Reverting these incorrect edits made everything fine. (coincidentely, we had a discussion about the class tree and what should be the rule, resulting into some talk about robustness. Hope it’s not a robustness test). Talk:Q63819493 had indeed an error but it was not because of this template. Is it a mispelling of another page ? author  TomT0m / talk page 20:18, 1 July 2019 (UTC)

@TomT0m:, Could you also look at Talk:Q22001389. It also runs out of memory. --Jarekt (talk) 13:36, 30 July 2019 (UTC)

@Jarekt: There is a couple of really wrong stuffs in the class tree of this item. It turns out, for example, that « wiktionary » is a superclass of « wiktionary linguistic version », but « wiktionary linguistic version » is a class of projects whereas « wiktionary » is a concrete project. A class of project can’t be a subclass of a concrete project. For some wrong reason a wiktionary edition is supposed to be … an industry. author  TomT0m / talk page 13:09, 31 July 2019 (UTC)

 Done Scholia

Can we include a link to Scholia (example = https://tools.wmflabs.org/scholia/Q42 )? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 09:33, 8 December 2019 (UTC)

 Support It would be a good idea PAC2 (talk) 07:01, 18 February 2021 (UTC)

List of subclasses

Can we add a link to a SPARQL query for the list of subclasses in addition to the list of instances? That would be helpful --Hannes Röst (talk) 15:20, 9 September 2020 (UTC)

@Hannes Röst: There are already three such at the bottom: Magnus’ tool, which creates a pretty tree-like output, but doesn’t show labels lately, and two SPARQL queries for direct and not necessarily direct subclasses. —Tacsipacsi (talk) 14:29, 11 September 2020 (UTC)

Add label at top of template?

Can we add the item label at the top of this template? I sometimes open several/many talk pages in different tabs and it would be nice to be able to quickly identitfy which item's talk page I'm looking at. — The Erinaceous One 🦔 11:49, 2 October 2020 (UTC)

I made the change. — The Erinaceous One 🦔 23:08, 2 October 2020 (UTC)

My change works most places, but it is displays "ITEM DOCUMENTATION" on Template:Item documentation, instead of human (Q5). — The Erinaceous One 🦔 10:48, 5 October 2020 (UTC)

Deployment strategy

I just discovered this template and I find it really useful. Is there any strategy or recommendation to deploy this template on all talk pages?

Is there any link between this tool which is manually added to every talk page and some other templates such as {{TP given name}} (@Jura1: which are directly integrated in talk pages using MediaWiki:Talkpageheader (@Jarekt:)? PAC2 (talk) 11:13, 27 December 2020 (UTC)

I've just launched a request for comments about the topic Wikidata:Requests for comment/How should we develop and deploy documentation for items ?. PAC2 (talk) 17:39, 10 January 2021 (UTC)

 Done Proposal to add two new queries in the Item documentation page

I suggest to add two new queries in the item documentation page : - the first one is the number of claims about the item by property type - the second one is the list of all claims about the item I've contributed to the sandbox, so you can see the result here Template:Item documentation/testcases. I find those queries really useful to learn more about an item. Tell me if you oppose or support my proposal. PAC2 (talk) 22:07, 20 January 2021 (UTC)

•  Support Those both sound useful to me! — The Erinaceous One 🦔 08:18, 23 January 2021 (UTC)

I've integrated the two new queries (see here). Let my know if there is some bug. PAC2 (talk) 21:11, 1 February 2021 (UTC)

 Done Proposal to add specific queries

I propose to add the {{TP award}} template for awards using the SWITCH command. See the difference in the source code and the output.

My idea behind is to add progressively class specific templates to the general {{Item documentation}} template.

I really believe that class specific predefined sparql queries have a great value for exploring wikidata and discover relationships between items.

Let me know if you support ({{Support}}) or oppose ({{Oppose}}) this suggestion. PAC2 (talk) 20:55, 2 February 2021 (UTC)

It is implemented in the main template (see diff). Let me know if there are some problems PAC2 (talk) 21:30, 6 February 2021 (UTC)

 Done Proposal to add subtemplate for organization

After the inclusion of {{TP award}}, I propose to add {{TP organization}} for items of class organization. The diff is here. Tell me if you {{Oppose}} or {{Support}} this suggestion before I merge it in the main template. Suggestions and improvement are welcome. PAC2 (talk) 21:00, 10 February 2021 (UTC)

•  Support but can we say “parent organization” rather than “mother organization” to match the property label? - PKM (talk) 06:27, 13 February 2021 (UTC)

Yes, I'll change it. PAC2 (talk) 09:52, 13 February 2021 (UTC)

•  Support Looks nice - and agree on 'parent' for English! ArthurPSmith (talk) 15:45, 15 February 2021 (UTC)
  • Hmm, I was expecting this to work for any item that was an instance of any subclass (transitively) of organization, but it seems only to work with if it's a direct instance? Most organizations are I think more specific in classification - businesses or universities or government departments, etc. ArthurPSmith (talk) 15:48, 15 February 2021 (UTC)

@ArthurPSmith: yeah, the actual syntax does only work with direct instance, which requires to have the list of all relevant instances. I'd be happy to find a better solution. Any idea or example ? PAC2 (talk) 20:34, 15 February 2021 (UTC)

I don't know much about templates so I don't know if it's possible, but I do know the constraints seem to allow following subclasses. Anyway, unless that can be fixed, can you add organization (Q43229), institution (Q178706), international organization (Q484652), government agency (Q327333), company (Q783794), professional association (Q829080), educational organization (Q5341295), educational institution (Q2385804), higher education institution (Q38723), school (Q3914), university (Q3918), college (Q189004) at least to the list of classes? ArthurPSmith (talk) 15:22, 16 February 2021 (UTC)

It’s possible in theory to traverse back along the subclass of (P279) chain in Lua, but it may quickly reach the 500 loaded entities that are allowed per page (or another Lua limit like memory limit). Unfortunately there’s no such efficient method available in templates/modules like SPARQL that the constraints can use. —Tacsipacsi (talk) 00:21, 17 February 2021 (UTC)

@Tacsipacsi: do you have any example of Lua code parsing all P279 subclasses? This wouldbbe a nice solution. PAC2 (talk) 19:42, 17 February 2021 (UTC)

I have some bug with the switch command. Let's see if I find a solution 😊 PAC2 (talk) 06:59, 18 February 2021 (UTC)

Merge is done but we need to find a better technique than this long list of values PAC2 (talk) 19:48, 18 February 2021 (UTC)

Thanks to the new {{SwitchClass}} template developed by TomT0m, we have a new version in the sandbox (https://m.wikidata.org/wiki/Special:MobileDiff/1396229578?diffmode=source) which works with every subclass. PAC2 (talk) 09:25, 5 April 2021 (UTC)

 Done Next idea : Create links with the wikiprojects based on P17, P27, etc

In Wikipedia in French, each article is related to a portal which is related to a portal. So it's easy to go from the article to the project and reach the community of interested contributors.

Wikidata has items and Wikiprojects but there is no links between items and wikiprojects. I think it would be useful to make a link to relevant wikiproject.

Here is a first version of what it could be. You can have a look at User:PAC2/Test to have a small test of what it could be.

What do you think of that new idea ? PAC2 (talk) 21:52, 18 February 2021 (UTC)

• @PAC2: I see you use country (P17). Maybe also use on focus list of Wikimedia project (P5008)?

I'll have a look PAC2 (talk) 22:21, 23 February 2021 (UTC)

 Done Include {{TP administrative area}}

After {{TP award}} and {{TP organization}}, I propose to include {{TP administrative area}} (see diff) for all administrative subdivision such as countries, regions, cities, etc. Your feedback is welcome and feel free to complete the list of relevant classes. For now, we have : | capital city (Q5119), big city (Q1549591), country (Q6256) U.S. state (Q35657), commune of France (Q484170), department of France (Q6465). PAC2 (talk) 22:20, 23 February 2021 (UTC)

Correction needed in the link List of instances

--MikePC (talk) 08:50, 26 February 2021 (UTC) The link List of instances [[1]] gives an additional Q into the query like in wd:QQ5.

@MikePC: Should be OK now. author  TomT0m / talk page 10:14, 26 February 2021 (UTC)

 Resolved Bug with Infobox for class chemical compound (Q11173)

In the code, we print {{Infobox}} if item is a chemical compound (Q11173).

{{#ifeq: {{is a|{{{1|{{PAGENAME}}}}}|Q11173}} | true
| <div style="background:#F0F0F0; border-radius: 4px; padding: 3px 10px; margin-bottom: 10px;">
{{Infobox|{{{1|{{PAGENAME}}}}}}}

As you can see (3S,5S)-3,5-dimethylpiperidine (Q40838069), there is a bug and {{Infobox}} doesn't work.

Should we remove this section of the code? PAC2 (talk) 22:08, 1 March 2021 (UTC)

I think that this discussion is resolved and can be archived. If you disagree, don't hesitate to replace this template with your comment. PAC2 (talk) 11:40, 4 April 2021 (UTC)

"Data to provide for this type of item" - where does this come from ?

N00b question: Looking around I couldn't find any explanation/documentation of why the Q5 example renders that nice extra block with the table "Data to provide for this type of item" while the other example doesn't. Is this an entity schema thing, or tied to constraints somehow? Would love to know how I make that part render when using the template. Moebeus (talk) 22:37, 3 March 2021 (UTC)

@Moebeus: There’s nothing semantic about it, the template simply includes Talk:Q5/class, which uses plain old wikitext templates. —Tacsipacsi (talk) 23:45, 3 March 2021 (UTC)

Aha, thank you so much for the explanation and quick reply! Moebeus (talk) 23:49, 3 March 2021 (UTC)

I think that this discussion is resolved and can be archived. If you disagree, don't hesitate to replace this template with your comment. Moebeus (talk) 23:50, 3 March 2021 (UTC)

Translations

Hi I think that langswitch should be removed and be transformed into the same way than https://commons.wikimedia.org/wiki/Data:I18n/Template:Graphs.tab --Bouzinac ^{💬●✒️●💛} 19:30, 5 April 2021 (UTC)

What would be the advantage? Is there a documentation for this method? PAC2 (talk) 20:46, 5 April 2021 (UTC)

Hi PAC2 More tabular translation data, more easy to translate crosswikis, to add translations. https://www.mediawiki.org/wiki/Template:Graph:Lines is used widely crosswikis and its translations are stored into file one https://commons.wikimedia.org/wiki/Data:I18n/Template:Graphs.tab .Bouzinac ^{💬●✒️●💛} 20:59, 5 April 2021 (UTC)

And will this template be used cross-wiki ever? I don’t think so. Wikidata has items, and that’s it. Local templates need local solutions. The Translate extension might be one, but unfortunately it doesn’t support having multiple Chinese translations (simplified and traditional), while LangSwitch does. —Tacsipacsi (talk) 00:39, 6 April 2021 (UTC)

Fyi, LangSwitch has been banned from enwiki. --Bouzinac ^{💬●✒️●💛} 07:36, 6 April 2021 (UTC)

Which is totally irrelevant here, since enwiki is a monolingual site and thus isn’t prepared for this kind of internationalization, while Wikidata is multilingual, and the MediaWiki message mentioned in the enwiki deletion discussion does exist in quite a few languages; actually all internationalization methods (apart from using MediaWiki messages directly) that work on talk pages use it. Without this hack, it’s simply impossible to tell the user’s preferred language. —Tacsipacsi (talk) 22:59, 6 April 2021 (UTC)

 Done Display item classification template only if the item is a subclass of something

{{Item documentation}} displays {{Item classification}} for all items. Yet, this template is only relevant if the item is a subclass of something else (ie has a value for subclass of (P279).

Therefore, I propose to display {{Item classification}} only if the item has a value for subclass of (P279) .

See the code source in sandbox and have a look at Template:Item documentation/testcases to check the behaviour.

If no one oppose this contribution, I will merge it in the main template in a few days]. PAC2 (talk) 06:15, 18 April 2021 (UTC)

 Done PAC2 (talk) 06:08, 21 April 2021 (UTC)

Fixed There was a small bug due to the fact that I was using ifexist instead of if. PAC2 (talk) 05:51, 23 April 2021 (UTC)

Next ideas

I have lots of ideas for this template. Here are my next ideas.

• Add a link to Scholia in the useful links section
•  Done Move the two generic queries to the useful links section
•  Done Move the list of instances from the useful link section to the {{Item classification}}
•  Done Add more generic queries for classes in the {{Item classification}}
• Develop new class specific templates
•  Done Complete the list of country specific projects

By the way

•  Done there is a discussion to remove the link to miga (which does not work anymore) from {{Item classification}}
• I've added an invitation to deploy {{Item documentation}} for cities in Wikidata:Status updates/Next

PAC2 (talk) 06:03, 23 April 2021 (UTC)

 Done Proposal to add more specific queries to the Item classification template

I've made a proposal to add more generic queries to {{Item classification}}. The discussion goes here Template_talk:Item_classification#Adding_more_generic_queries. PAC2 (talk) 14:05, 25 April 2021 (UTC)

 Done Regrouping useful links and generic queries section, removing the list of instances

I propose to group together the useful links and the generic queries sections. There is no reason to have two separate sections.

I also remove the list of instances link since it is now part of the Item classification template.

See Template:Item documentation/testcases to compare the actual version versus the sandbox. PAC2 (talk) 19:03, 30 April 2021 (UTC)

Improving the style

The light blue background seems a bit old style to me. In the sandbox, I propose a lighter style based on a very light grey. See Template:Item_documentation/testcases. Do you agree with this change? PAC2 (talk) 13:30, 2 May 2021 (UTC)

I think the current blue is elegant and not outdated at all. Also, even if there’s an overwhelming support for using grey (which I personally don’t like), at least choose a darker one—this one doesn’t stand out at all, it’s almost white. —Tacsipacsi (talk) 20:29, 2 May 2021 (UTC)

Thanks for your feedback. I'll not change the style. PAC2 (talk) 05:17, 4 May 2021 (UTC)

 Done New generic queries for occupations

I propose to add {{Generic queries for occupations}} template for all items of class occupation (Q12737077). See the sandbox for the difference and the Testcases .

By the way, I have redesigned the testcases page using flexbox layout. You may have two columns layout on large screen and one column layout on small screen.

PAC2 (talk) 05:33, 10 May 2021 (UTC)

This is now integrated in the main template. PAC2 (talk) 19:53, 12 May 2021 (UTC)

 Done Proposal to add occupation based generic queries

{{TP organization}}, {{TP administrative area}}, {{TP award}}, {{Generic queries for occupations}} are based on the value of instance of (P31). It is also relevant to have generic queries based on the occupation (occupation (P106) of the item. I propose the first generic queries based on occupation of the item with {{Generic queries for filmmakers}}. It relies on a new template : {{HasOccupation}}.

You can see an example in the testcases : Template:Item_documentation/testcases#Alice_Guy.

Feedback and contributions are welcome. PAC2 (talk) 20:44, 12 May 2021 (UTC)

 Done Proposal to add template Generic queries for actors

Following the example of {{Generic queries for filmmakers}}, I've designed a new occupation specific template {{Generic queries for actors}}.

I've added the template in the sandbox for all items with occupation (P106) actor (Q33999).

As usual, you can check the result at the bottom of Template:Item documentation/testcases with Alice Guy's example. PAC2 (talk) 05:37, 17 May 2021 (UTC)

Proposal to add image at the right

In the sandbox, I've tested a version with an image (P18) displayed at the top right of the template. See Template:Item documentation/testcases. I think it's great. What do you think ? PAC2 (talk) 05:42, 21 May 2021 (UTC)

Why? The purpose of this template is to provide information that’s not directly available on the item page. image (P18) is perfectly available, there’s no need to duplicate it. This template is already getting too long only with useful information, there’s no need to put also some useless stuff in it. —Tacsipacsi (talk) 11:43, 21 May 2021 (UTC)

OK, my idea was to make it look more attractive but you're right. It's a good idea to keep it simple. PAC2 (talk) 19:44, 8 June 2021 (UTC)

I propose to add a link to Scholia in the useful links section. See the sandbox. PAC2 (talk) 19:54, 8 June 2021 (UTC)

Jura1 I'm not sure to understand your point. Do you mean deploying Item documentation template through MediaWiki:Talkpageheader or adding [..] to {{Item documentation}}? PAC2 (talk) 07:42, 6 November 2021 (UTC)

• By including them directly in the interface message. Wikidata is a database. Contrary to Wikipedia, we don't need to add these manually. Let's not carry over manual habits from Wikipedia. --- Jura 07:48, 6 November 2021 (UTC)

I've launched a request for comment in January about this topic Wikidata:Requests for comment/How should we develop and deploy documentation for items ?. There was no clear conclusion. PAC2 (talk) 16:21, 6 November 2021 (UTC)

There doesn't seem to be consensus to create thousands of otherwise empty talk page.

Back when this was started at Wikipedia, they lacked db functions to implement this without adding such templates, but at Wikidata the functions are available and, given that this is the main Wikibase installation, we should know better. --- Jura 07:26, 7 November 2021 (UTC)

I still not really understand what you mean with DB functions and I believe that manual editing of talk pages may have some advantages but it's worth having the debate. I think it would be useful to ask the question in Wikidata:Project_chat. PAC2 (talk) 20:51, 8 November 2021 (UTC)

Query linking items with lexemes

In the sandbox, I propose a new query (Special:MobileDiff/1663116140?diffmode=source) showing the list of all lexemes which correspond to the item by their sense.

I think it's very important to make the link between items and corresponding lexemes (see this discussion with Pa2chant.bis).

However, I still have some questions. This query is not relevant for humans, works or organizations since they should not have corresponding lexemes. I don't know what is the good filter.

Also, I don't know if we should show lexemes in all languages or only in the preferred language of the user.

What do you think? PAC2 (talk) 07:13, 19 June 2022 (UTC)

 Checked : I've integrated the query. We will see if we need to add filters in the future. PAC2 (talk) 20:09, 21 June 2022 (UTC)

Proposal to add {{Generic queries for transport network}}

With Bouzinac we've designed {{Generic queries for transport network}} for all items of class public transport network (Q18325841). We propose to add it to {{Item documentation}}.

Proposal to add {{Generic queries for architects}}

Article in the Signpost

In the last edition of the Signpost, I've written an article which explains how Item documentation can be used for assisting Wikipedia contributors. See the article here : Wikidata insights from a handy little tool. PAC2 (talk) 05:38, 15 August 2022 (UTC)

New tool needed

We need a new tool called "depicted_by at Commons" (or some similar name) at Wikidata that links to, and gives a count, of items stored in Commons that use a Q-number from Wikidata in the depicts statements. If the tool existed I could click on it like I do at "What links here" and it would give me a count of how many documents at Commons link to say George Washington (Q23) and then list them. While that search would be large, and the count more important, for obscure people it would be very helpful to know there is an image at Commons and provide a link. Sometimes the person will be in a news article or we have an image of them. Currently we rely on the link to the Commons category, but there is always a mismatch between "depicts" and "Category:". If there is only one item, most people would not bother to create a category. It would help in deletion debates to know that a Wikidata entry is in-use at Commons with a depicts statement. We have deleted several Wikidata entries because we were not aware they were in-use at Commons. --RAN (talk) 00:28, 15 August 2022 (UTC)

Yes I love the idea. We need to have a federated query between query.wikidata.org and https://wcqs-beta.wmflabs.org/. Do you have any example of such a query? This would be a good starting point. PAC2 (talk) 05:27, 15 August 2022 (UTC)

A simple thing to do would be to add a link to a structured search on Commons.

For instance you can have the search of all medias in Commons with P180 equal to George Washington (Q23) with this url https://commons.m.wikimedia.org/w/index.php?search=haswbstatement%3AP180%3DQ23. PAC2 (talk) 06:13, 15 August 2022 (UTC)

We can also add a link to the new View it tool : https://view-it.toolforge.org/?q=Q243 PAC2 (talk) 19:42, 30 August 2022 (UTC)

Class information

At the moment all class-related information (not just the classification) is collapsed in the "Classification of the class XXXX" section.

As a result, I have only just found the very very useful class-related queries that the template offers, which I hadn't previously realised existed.

Can I suggest maybe to move these out of the collapse-box, so that it is only the (potentially lengthy) classification tree that is collapsed? I think that could be quite helpful to people, to make these (very useful) queries more obvious. Thanks, Jheald (talk) 09:28, 14 September 2022 (UTC)

Thanks a lot for this feedback. Right now, the classification tree and the class specific queries are in the same template. Therefore, the collapse apply to both automatically. However we could imagine to split {{Item classification}} into 2 templates. We could for instance create {{Generic queries for classes}}. PAC2 (talk) 17:13, 15 September 2022 (UTC)

Perhaps a useful re-factoring anyway ? Jheald (talk) 17:25, 15 September 2022 (UTC)

 Support I think this would make the template easier to read. — The Erinaceous One 🦔 06:26, 30 November 2022 (UTC)

Thanks for the suggestions. I will do this as soon as possible. PAC2 (talk) 05:48, 14 March 2023 (UTC)

Proposal to list statements with item as qualifier value, also references

@PAC2: I currently see no immediate means of finding cases where the item is used as a qualifier value. I propose adding "All qualifiers involving ..." alongside the existing "All claims about ..." for the sake of completeness. I don't think the two (claims and qualifiers) should be merged into a single query; it would make the resulting table too complex to read.

I would however consider including references and qualifiers in the same query, as the average number of references involving a particular item is probably too small to warrant a separate lookup, and the two could use the same table columns (with a separate column indicating Qual or Ref as appropriate to allow sorting them into different table sections). Maybe "All qualifiers/references involving ..." in that case then? --SM5POR (talk) 07:48, 10 March 2023 (UTC)

@SM5POR thanks for the suggestion. It's a great idea. I think it would be better to separate qualifiers and references in two separate queries.

Do you have any example query which we could use in the template? PAC2 (talk) 05:51, 14 March 2023 (UTC)

@PAC2 Yes, I agree; I changed my mind realizing the large number of references pertaining to items like German Wikipedia (Q48183). Here is a qualifier value example: All qualifiers involving consumer; it's based on the "All claims about" query. I'm not too sure about the optimization though; it may be possible to improve. --SM5POR (talk) 09:15, 15 March 2023 (UTC)

I've implemented the query in the sandbox. See here and test cases. PAC2 (talk) 21:25, 9 April 2023 (UTC)

I suggest also to add a query which adds all statement with the item as a reference. Here is my example query :

The following query uses these:

• Items: Mediapart (Q619342)   

  #title: List of statement with Q619342 as a reference 
  SELECT ?subject ?subjectLabel ?property ?propertyLabel ?object ?objectLabel ?reference ?referenceLabel WHERE {
    hint:Query hint:optimizer "None".
    ?reference wikibase:reference ?pr.
    ?ref ?pr wd:Q619342.
    ?statement prov:wasDerivedFrom ?ref.
    ?subject ?p ?statement.
    ?property wikibase:claim ?p;
      wikibase:statementProperty ?ps.
      ?statement ?ps ?object.
    SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE], en". }
  }

Only administrators can now change Item documentation

I discover that following @Ameisenigel contribution from last week (see https://www.wikidata.org/w/index.php?title=Template%3AItem_documentation&diff=prev&oldid=1872522170&diffmode=source), only administrators can now contribute to the Item documentation template. PAC2 (talk) 20:41, 18 April 2023 (UTC)

I have protected this template because it is included in MediaWiki:Talkpageheader. We usually protect templates if they are used in the interface (e.g. the templates that are included in MediaWiki:Watchlist-summary are protected as well). Of course changes can be requested through {{Edit request}}. --Ameisenigel (talk) 08:31, 19 April 2023 (UTC)

Thanks for your answer. I'll try to understand the process. PAC2 (talk) 21:20, 19 April 2023 (UTC)

Add Czech translation

{{Edit protected}}

I’ve prepared a Czech translation of the template. Could some admin please apply User:Mormegil/Item documentation (diff)? Thanks. --Mormegil (talk) 17:41, 6 May 2023 (UTC)

 Done. Can you please explain your modification concerning one CA translation (233rd line)? Was it intentional? Bencemac (talk) 12:19, 10 May 2023 (UTC)

Thanks; yes, it was intentional, the “by property” part was IMHO an obvious forgotten remnant of the previous query caption. --Mormegil (talk) 07:38, 11 May 2023 (UTC)

Thanks for clarifying! Bencemac (talk) 21:02, 11 May 2023 (UTC)

Lua error for deleted items

I noticed in the talk of a deleted item (Talk:Q19325342) the following error: "Lua error in Module:Requests/union_of at line 199: attempt to index local 'item' (a nil value).". Could it be solved (e.g. avoiding this section for items having been deleted?). Thanks, --Epìdosis 15:55, 20 July 2023 (UTC)

I also get "=== Union and disjoint queries===" instead of

PositionHolderHistory|id=

Can{PositionHolderHistory|id= be part of the autodescription for position=? See: Talk:Q19546. The charts can get deleted or archived, or pushed down by discussions. RAN (talk) 23:07, 21 August 2023 (UTC)

The header ({{PositionHolderHistory}}) could, but I don’t think the bot would find it that way, and it would be even more prone to breakage anyway if the header and the actual table would be defined at different places. The body itself couldn’t, since the body content is generated by the bot and differs from position to position, so including it in this template is not an option. —Tacsipacsi (talk) 23:27, 22 August 2023 (UTC)
