I am presuming that by "arbitrary" that this is usage of a reference point outside of the defined matching/target page.

If we are going to do that, it would probably be useful to explain the points, and the purpose from the WS point of view, rather than the technical means from the WD side. [Simpler language for a community that probably still hasn't got its head wrapped around the concept and broader use of WD, ie. at the moment it adds work to add WD data, for no perceived local benefit at this time)

@Billinghurst: This ticket is for tracking the technical side. The announcement to the project will have more explanation just like it did for Dutch Wikipedia and French Wikisource.

yes @Lydia_Pintscher though this is tagged for Wikisource, so those netizens will take interest in what is being planned for their use.

In such a circumstance there would be value in adding some external links of the general idea for the communities' perusal. IMO always best to bring the communities with you and start the engagement early, rather than those who are suspicious feeling that something is being foisted upon them. So please consider adding the corresponding link to wikidata pages FAQ/...

@Billinghurst agree, we should add more explanation when making these tasks.

https://www.wikidata.org/wiki/Wikidata:Arbitrary_access has some more details about what arbitrary access is about.

I think we need to wait for T89002 to be resolved before enabling arbitrary access for srwikisource and zhwikisource since they have language variants.

@greg: the new title clashes with T98303: Deploy usage tracking and arbitrary access to itwiki
