📅Wikidata Query Service (WDQS) Days 2026 — Oct 17–23

WDQS is migrating from Blazegraph to QLever. If you run maintenance queries or maintain tools/services on it, this affects you!

Join us for updates, hands-on workshops on query rewriting, demo on the query rewriting tool and Q&A's with the dev teams. Sessions will repeat across time zones, all recorded for later or repeat viewing.

Co-organized by Wikimedia Deutschland + WMF's Wikidata Platform team.
