== Support for P5017 ''last update'' ==
<!-- [[User:DoNotArchiveUntil]] 15:16, 18 August 2025 (UTC) -->{{User:ClueBot III/DoNotArchiveUntil|1755530186}}
{{ping|Thayts|Janhrach}} Hi. Is it possible to add support for [[:d:Property:P5017|P5017 ''last update'']] property? It seems to be perfectly valid citation/reference property for continuously updated sources to indicate last-update date of the version actually cited and it is being used all over WD this way, see [[d:Special:WhatLinksHere/Property:P5017|backlinks]] and [https://linkcount.toolforge.org/?project=www.wikidata.org&page=Property%3AP5017 stat]. Right now rendering attempt of a citation having this property filled here on enwiki leads to a nasty error output:
:<code><nowiki>{{#invoke:wd|reference|Q733993|P2046}}</nowiki></code> → <ref name="wikidata-8d9471ae1372c5ce8f22dc9a33852d9f3e9a6bc3-v18"><span style="color:#dd3333">
Error: Unable to display the reference from Wikidata properly. Technical details:
* Reason for the failure of {{tl|Cite web}}: The Wikidata reference contains the property {{property|P5017}}, which is not assigned to any parameter of this template.
* Reason for the failure of {{tl|Cite Q}}: The Wikidata reference contains the property {{property|P5017}}, which is not assigned to any parameter of this template.
See [[Module:wd/doc#References|the documentation]] for further details.
</span>
[[Category:Module:Wd reference errors]]</ref>
<references />

On other wikis such citations are citable at least, even if the last update value is not used. E.g.: [https://cs.wikipedia.org/wiki/Special:ExpandTemplates?wpInput=%7B%7B%23invoke%3AWikidata%7CformatStatements%7Cid%3DQ733993%7Cproperty%3DP2046%7Crank%3Dbest%7Climit%3D1%7Cshowqualifier%3Dp585%7Csort%3Dp585%7Cinvert%3Dtrue%7Cshowsource%3Dtrue%7D%7D].

If there really is a good reason to keep current strict semantics (i.e. to fail with error on ''any'' unknown/unmapped citation property instead of just ignoring it or maybe including some hidden note and a monitoring cat. assignment), maybe an explicit whitelist of "tolerated" though unused citation properties would be useful. It doesn't make much sense to be completely unable to render citations that are valid on WD itself and renderable on other projects. And another negative side effect of this approach is that if anyone adds such an unsupported property on WD side later, unaware of the limitations of this module, it will introduce an unintentional error here, that is out of control of the original author, who inserted a (then working) citation. That's definitely not nice behavior. --[[User:Teslaton|Teslaton]] ([[User talk:Teslaton|talk]]) 18:41, 24 November 2024 (UTC)

:Hello, sorry for the late reply.
:As for adding P5017, it is of course possible. Which Cite-web parameter should it be mapped to? Should it override publication date? 
:Note that [[:wikidata:Help:sources]] does not mention this property at all, which, in itself, is not a problem. I am mentioning the Wikidata page because it is worth noting that references on Wikidata aren't really standardized. That page is, at least in my knowledge, the only one to say something about formatting references, yet it seems to be far from complete.
:Unfortunately, there is no simple way to fix the citation-rendering function to just ignore unknown properties – outputting an error on failure is an inherent property of the (very simple) algorithm, as long as we want it to always produce understandable results. For example, an exteral id property (together with a "stated in" property) is sufficient to generate a Cite-web citation. However, this combination is also sufficient to create a Cite-Q citation. How should the module decide which citation template to use?
:The original algorithm solved this problem by not using a citation template if the Wikidata reference contained any properties not mapped to its parameters. If neither of the templates could be used, a fallback citation was generated. However, this fallback was removed (almost two years ago), because it was dissimilar to existing citation styles and sometime quite human-unfriendly.
:This is a very conservative solution – it rarely produces gibberish citations (e.g. leaving out information essential to the reference), but always fails on atypical Wikidata citations.
:If you have ideas for a better algorithm, please share your ideas.
:PS: After finishing writing this reply, I got an idea: maybe a good solution would be to ignore  properties that are unknown to ''both'' of the citation templates (and issue an invisible error when encountering them). I will think about it.

=== Proposed fix ===

I have implemented (in /sandbox) support for configuring the module (in /i18n) for using multiple Wikidata properties as sources for citation paramenters. These properties are ordered – each has it priority, which determines when to use the said property. I used this functionality to fix the above issue. (Both ''publication date'' and ''last update'' are used as a source for the {{mono|date}} citation argument, but ''last update'' has higher priority.) I also used this mechanism to reimplement the usage of ''subject named as'' as a fallback for {{mono|title}}. Your comments are welcome.

== Retrieving multiple wikidata property values in one call ==

I am trying to retrieve multiple property values in one call but it is ignoring the other properties I give so I only ever get one property value. I must not be giving things in the correct order but none of the examples help me. For example, given a mountain name, I want to retrieve the elevation, prominence, mountain range, coordinates and the first ascent significant event.
So given this:
     P4552 = mountain range
     P2044 = elevation
     P2660 = prominence
     P625  = coordinates
     P793  = significant event; Q1194369 = first ascent; P585 = point in time
I can get all the values if I code one call per property but how do I code it so I can get all the properties in one call?
The documentation for the "property" command says "Returns the requested property – or list of properties". Yet, I see no example or syntax of how to specify this list of properties.<br/>

If I code the following, I only get the value of property P2044.<br/>
   <nowiki>{{#invoke:wd|property|qualifier|page=Mount Robson|P2044|P2660|P4552|P625|P793|Q1194369|P585}}</nowiki>

:Have you tried using <code>properties</code> instead of <code>property</code>? [[User:Janhrach|Janhrach]] ([[User talk:Janhrach|talk]]) 20:45, 23 January 2025 (UTC)
::Yes, first thing I tried but it's not for specifying multiple properties to return but rather for returning multiple values of the given property. [[User:RedWolf|RedWolf]] ([[User talk:RedWolf|talk]]) 22:04, 23 January 2025 (UTC)
:::It seems that this module does not support this functionality – the diagram at [[Module:Wd#Positional arguments]] apparently says only one <code>property_id</code> argument is supported. The description you quoted from the documentation probably refers to using <code>properties</code>. [[User:Janhrach|Janhrach]] ([[User talk:Janhrach|talk]]) 13:29, 24 January 2025 (UTC)

== Retrieve foreign Wikipedia page title ==

I want to use the template to retrieve the foreign Wikipedia title of an article, given the local title. As an example: I have 'Eiffel Tower', and I want to retrieve the name '''Eiffelturm''' from the name of the corresponding page on de-wiki, according to the information available at the bottom of page [[d:Q243#sitelinks-wikipedia|Q243]].

I am new to the wikidata template, and I have discovered how to do some of what I need to do, for example: I see that <code><nowiki>{{wikidata|label|raw|page=Eiffel Tower}}</nowiki></code> gives me back {{kbd|{{wikidata|label|raw|page=Eiffel Tower}}}}. I see how to get various properties, like where it is located:
* <code><nowiki>{{wikidata|property|page=Eiffel Tower|P17}}</nowiki></code> ⟶ {{wikidata|property|page=Eiffel Tower|P17}}
But I don't see what the property name or id of the foreign wikipedia property is, so I can retrieve the German page title. What I want logically, I think, is something like this, maybe:
* <code><nowiki>{{wikidata|qualifier|page=Eiffel Tower|P99999|de}}</nowiki></code> ⟶ Eiffelturm
where {{kbd|P999999}} is an imaginary property number for 'Wikipedia language link' and {{kbd|de}} is the language code for the foreign Wikipedia containing the title I am looking for. But I can't find a property value for Wikipedia site link. There must be a property or something for the wikipedia names, but I can't find it. Maybe it's not a property, but something else?

== "Multilanguage" not working ==

I noticed that the example <code><nowiki>{{wikidata|property|multilanguage|Q55|P1549|P407=Q36846}}</nowiki></code> on [[Template:Wikidata]] no longer works – the output is empty. This seems to happen generally when trying to retrieve language-specific values of P1549 using "multilanguage".

Does anyone know how to fix or work around this issue? --[[User:Volvox|Volvox]] ([[User talk:Volvox|talk]]) 18:40, 9 April 2025 (UTC)

: {{Reply|Volvox}} It appears that <code>multilanguage</code> itself works, as in the following for the {{Prop|1549}} property of {{Q|55}}.
: <code><nowiki>{{wikidata|property|multilanguage|Q55|P1549}}</nowiki></code> (show one value)
:: {{wikidata|property|multilanguage|Q55|P1549}}
: <code><nowiki>{{wikidata|properties|multilanguage|Q55|P1549}}</nowiki></code> (show all values)
:: {{wikidata|properties|multilanguage|Q55|P1549}}
: I think the problem might be that {{para|P407|Q36846}} as shown in that example is looking for a {{Prop|407}} qualifier containing {{Q|36846}}, which is not how the {{Q|21044568}} datatype stores the language. You can see how it is stored by expanding the following.
{{Collapse|title=Output of <code><nowiki>{{examine|P1549|qid=Q55}}</nowiki></code>|content={{examine|P1549|qid=Q55}}}}

== Intenationalisation of dates ==

Hi,
a Spanish Wikipedian noted that dates in Spanish use the article "de". For instance, "10 november 1992" will be "10 '''de''' noviembre '''de''' 1992". Is there a way to account for this in the i18n code? [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 08:31, 5 June 2025 (UTC)

:Actually, secondary question: is there a way to account for the plural form for currencies? Like "1 euro, 2 euros". [[User:Julius Schwarz|Julius Schwarz]] ([[User talk:Julius Schwarz|talk]]) 08:33, 5 June 2025 (UTC)
