Hello, everyone – We have our next LD4 Wikidata Affinity Group Session on Friday, October 30, 2026 11am PT / 2pm ET / 18:00 UTC / 7pm CET. 'Tis the season for another WitchyData Working Hour! To celebrate Halloween, we're tackling the scariest thing in all of Wikidata: statements without references. Join us for a hands-on working session where we'll hunt down unreferenced statements on items about horror movies, track down real published sources, and add references so the data can finally rest in peace. No experience needed – we'll show you how to conjure a reliable reference. Come cite with us!
