Wikidata Platform Newsletter - May 2026
[edit]
This is the 6th issue of our monthly newsletter! The next issue will be published in May 2026.
- Backend replacement and architectural design proposals: For the past few months, we've shared learnings from our investigations into backend replacement, and today we are sharing our recommendations for a new RDF database to replace and accompanying technical architecture for the migration away from Blazegraph as the backend of the Wikidata Query Service (WDQS). These documents outline the selected direction and how the new architecture is designed to improve scalability while making future backend changes easier.
- We are inviting feedback from the Wikidata community and other WDQS users until 25th May 2026, particularly on:
- Any important considerations we may have missed
- How your WDQS use cases, tools, or workflows may be affected
- We encourage you to share feedback on the migration discussion page. You can also join our upcoming office hour (Next tomorrow, May 12th) to ask questions and discuss your use cases.
- To help identify higher-risk areas, we have created a page to track high-impact use cases and tools. This page is not intended to catalogue all WDQS usage, but to highlight complex or critical cases that may require additional attention.
- Blazegraph Migration Office Hour (May session): Our next Blazegraph Migration Office Hour will take place on Tuesday, 12 May 2026 (Tomorrow) at . This session is focused on supporting the migration away from Blazegraph as the backend of WDQS. Whether you have questions, need clarification, or want to discuss how your use case may be affected. You can register for the session via the event page.
- In preparation, we encourage you to add questions, feedback, or migration-related support needs to this etherpad. This helps us shape the agenda and focus on the most relevant topics during the session.

Specifically we are looking at checking if there is any difference in the rendered article before and after the change coming from Wikidata

Development
- Tighter connection of the Wikibase Ecosystem: We've been working on making it possible to use Wikidata Items (and later from other Wikibase instances) as values in statements on other Wikibase instances. You can now try it out on a demo system or set up your own test instance to give it a try. More details in the announcement.

- Mobile statement editing:
- We worked on reducing the load for users with limited data
- We are continuing to fix issues uncovered in testing
- Making Wikiprojects more visible: We are getting ready for testing of the prototype. We'll be adding links to the respective Wikirojects on Item pages in the tools menu to make it easier for people to find the corresponding Wikiprojects. This is based on statements already on the Item such as specific external IDs.
