Wikibase is the powerful, flexible and customizable knowledge base software that drives Wikidata. With MediaWiki as its front end and a rich JavaScript interface for data management, Wikibase makes collaboration easy for humans and machines alike, and its data model prioritizes language independence and knowledge diversity.
Wikibase's robust data export options include JSON, RDF/XML, N3, YAML and more—and it provides a powerful SPARQL query interface that supports federated queries, extending the potential data available from a single node to thousands.
