Welcome!

The Data Reuse Days 2025 is an online event focusing on how people and organizations use Wikidata's data to build interesting applications and tools. It aims to bring together data reusers and editors to learn from each other and discover cool Wikidata-powered applications. We will also cover technical aspects of Wikidata and share research and ideas for the future of reusing Wikidata’s data.

How does it work?

The event is taking place online, we will have sessions taking place during periods of 2 hours through 8 days: from February 18 to 27, 2025. You will be able to join sessions live, or to watch the replay later on. You will find the schedule below on this page. The sessions take place in English, and are open to everyone interested in the topic of data reuse.
