Wikibase/FAQ

What is the difference between Wikibase and Wikidata?
Wikibase is a suite of knowledge-base software for managing linked open data, originally written for and still used by the Wikidata project.

Wikidata is the largest instance of Wikibase, a free knowledge base that anyone can edit. Its data is used by Wikipedia, by its sister projects and by anyone else who wants to make use of a large amount of open general-purpose data.
