Wikidata is the free, collaborative knowledge base behind Wikipedia and many other Wikimedia projects. The Web site has been online since late 2012 and has since become an important data provider for Wikipedias in all languages. Ten thousands of users have contributed statements about millions of entities. In December 2013, Google announced that their own collaboratively edited knowledge base, Freebase, is to be discontinued in favour of Wikidata. The research group Knowledge-Based Systems is working in close cooperation with the development team behind Wikidata, and provides, e.g., the regular Wikidata RDF-Exports.
Development of Wikidata started in April 2012 with a team of developers based on the Berlin offices of Wikimedia Germany. The project was heavily inspired by Semantic MediaWiki and Markus Krötzsch has been acting as an architectural advisor to the project since its inception.
