Hello lovely ambassadors, I am forwarding an email about an upcoming change for the Wikidata Query Service. This is relevant for you or your community if you rely on SPARQL queries to Wikidata that touch Items for scholarly articles. If you have any questions please don't hesitate to ask on the talk page.
Cheers Lydia ---------- Forwarded message --------- From: Guillaume Lederrey <[email protected]> Date: Tue, Sep 3, 2024 at 10:01 PM Subject: [Wikidata-tech] [BREAKING CHANGE ANNOUNCEMENT] Wikidata Query Service graph split available in production; scholarly entity queries require migration by March 2025 To: Discussion list for the Wikidata project. <[email protected]>, Wikidata technical discussion <[email protected]>, Wikimedia developers <[email protected]> Hi all! As part of the WDQS Graph Split project,[1] we have new SPARQL endpoints available for serving the “main”[2] and “scholarly”[3] subgraphs of Wikidata. As you might be aware we are addressing the Wikidata Query Service stability and scaling issues. We have been working on several projects to address these issues. This announcement is about one of them, the WDQS Graph Split.[1] This change will have an impact on certain uses of the Wikidata Query Service. We are now entering a transition period until the end of February 2025. The three SPARQL endpoints will remain in place until the end of the transition. At the end of the transition, query.wikidata.org will serve the main Wikidata subgraph (without scholarly articles). The query-main and query-scholarly endpoints will continue to be available after the transition. If you know to want more this change, please refer to the talk page on Wikidata.[4] Have fun!
