  • 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!
