Wikidata:Main Page
Wikidata is a free and open knowledge base that can be read and edited by both humans and machines.
Wikidata acts as central storage for the structured data of its Wikimedia sister projects including Wikipedia, Wikivoyage, Wiktionary, Wikisource, and others.
Wikidata also provides support to many other sites and services beyond just Wikimedia projects! The content of Wikidata is available under a free license, exported using standard formats, and can be interlinked to other open data sets on the linked data web.

- 📢 WikiProject Days 2026 is coming. June 19 to 21 online. We will talk about how WikiProjects can be used as a space to connect with others and inform data modelling and quality decisions. Sessions will include how to make Wikiprojects more visible, create guidelines for good WikiProjects, and bring life back into neglected WikiProjects. Propose a session by May 26 or register to attend. Everyone is welcome.
- Mobile editors can now edit all datatypes directly in the mobile view. To help improve this new interface, Wikimedia Deutschland is looking for volunteers (especially editors from right-to-left languages) for UX testing sessions. Participants will be compensated for their time. Sign up here and learn more on the project page: Mobile editing of statements.
- 2025-11-12: Temporary accounts were deployed on Wikidata. From now on unregistered editors will get a temporary account automatically assigned to them, instead of being identified by their IP addresses.
