Tool of the week

• Wdactle game -- is a Wikidata version of Redactle! It's a game where you are shown a Wikidata Item with all labels and words redacted and have to figure out what it is. Guessing a word reveals all the places where it is used. Built by Luca Werkmeister during the Wikimedia Hackathon 2025.

Other Noteworthy Stuff

• ⚠️ Wikidata Query Service graph split: As you know Wikidata Query Service was no longer able to handle the complete set of data Wikidata has. To address this the graph in Wikidata Query Service has now been split into a main graph (that continues to be at query.wikidata.org) and a scholarly graph (that is at query-scholarly.wikidata.org). For more details please see Wikidata:SPARQL query service/WDQS graph split.
• Join the Wikidata:Impact stories global campiagn. We're celebrating the amazing Wikidata community - editors, developers, librarians, and creators - and inviting you to share how Wikidata is used. Your story can inspire others and grow the community. Submit yours or nominate a cool project by June 6.
