Events

• Upcoming events:
  • Next Linked Data for Libraries LD4 Wikidata Affinity Group session 3 March, 2026: We have our next LD4 Wikidata Affinity Group Session on Tuesday, March 3 9am PT / 12pm ET / 17:00 UTC / 6pm CET (Time zone converter). Wikiproject P244 maintenance uses SPARQL queries to identify and resolve two types of constraint violations in Wikidata: instances of Wikidata items with more than one LCNAF identifier and instances of the same LCNAF identifier existing on more than one Wikidata item. The February 17th session walked participants through how to resolve the former issue, while the March 3rd session will focus on the latter. This session will be more discussion-focused, since instances where two LCNAF identifier have the same Wikidata item can be difficult to resolve because of Wikidata’s innate quirks. Maybe your ideas will become the official best practice!

Development

• Tighter connection of the Wikibase Ecosystem: We've been working on making it possible to use Wikidata Items (and later from other Wikibase instances) as values in statements on other Wikibase instances. You can now try it out on a demo system or set up your own test instance to give it a try. More details in the announcement.
• Wikidata integration in the Wikimedia projects: We are continuing the work on showing less irrelevant changes on recent changes and watchlist on Wikipedia and co by trying to determine if an edit from Wikidata actually changed the rendered article or not
• Mobile statement editing:
  • We worked on reducing the load for users with limited data
  • We are continuing to fix issues uncovered in testing
• Making Wikiprojects more visible: We are getting ready for testing of the prototype. We'll be adding links to the respective Wikirojects on Item pages in the tools menu to make it easier for people to find the corresponding Wikiprojects. This is based on statements already on the Item such as specific external IDs.
