Wikidatathe free knowledge base that anyone can edit – is a new Wikimedia Foundation (WMF) hosted and maintained project, founded 2012.

Wikimedia Wikidata aims to create a free knowledge-base about the world that can be read and edited by humans and machines alike. It will provide data, collectively known as 'wikidata' in all the languages of the Wikimedia projects, and allow for the central access to data in a similar vein as Wikimedia Commons does for multimedia files. Wikimedia Wikidata uses a dual licensing scheme: "All structured data from the main and property namespace is available under the Creative Commons Public Domain Dedication CC0 License; text in the other namespaces is available under the Creative Commons Attribution/Share-Alike 3.0 License".

Prior to its WMF rollout, wikidata was originaly used extensively by OmegaWiki.

The Wikimedia Foundation (WMF), founded 20 June 2003, is the non-profit organization responsible for a very large number (over 900 in total) of very active wikis, grouped together and known as 'projects'; as well as the wiki engine software initially developed by themselves, known as MediaWiki. The Foundations' major wiki projects include Wikipedia (encyclopedias), Wiktionary (dictionary and thesaurus), Wikiquote (quotations), Wikibooks (open content textbooks), Wikisource (free content primary and secondary source texts), Wikinews (news source), Wikiversity (open learning community), Wikispecies (free species directory), and many others as listed below. Most of these projects have separate wiki versions written in many different languages. There is also the Wikimedia Commons (shared repository for images, videos and other media files), Wikidata (central space knowledge base for data used on all WMF projects), and the Wikimedia Meta-Wiki (coordination of issues common to all Wikimedia projects). The Foundations' global reach is nurtured in its Incubator, where all new language versions for all projects are initiated and developed before being rolled out. Its most recent major project, Wikivoyage (a 'travelpedia'), was inducted to WMF in late 2012.

Wikimedia Foundation is a member of the Open Source Initiative.
