Next LD4 Wikidata Affinity Group Session on Tuesday, March 3, 2026

[Hilary K Thorsen]

Hello, everyone –

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!

Call Details: Date and Time: Tuesday, March 3 9am PT / 12pm ET / 17:00 UTC / 6pm CET (Time zone converter)

The LD4 Wikidata Affinity Group is associated with the LD4 Community and investigates how libraries can contribute to and better integrate library metadata with Wikidata to improve access to library resources on the web. The Affinity Group calls provide an informal space to share information and learn more about Wikidata.
