Wikidata – the free knowledge base that anyone can edit – is a vibrant Wikimedia Foundation (WMF) hosted and maintained wiki project, founded 2012.

Wikidata is a free, collaborative, multilingual, secondary database, collecting structured data to provide support for Wikipedia, Wikimedia Commons, the other wikis of the Wikimedia movement, and to anyone in the world.

Powered by MediaWiki and Wikibase, 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, in the form of 'structured data', collectively known as 'wikidata', in all the languages of the Wikimedia Foundation projects, and allow for the central access to data in a similar vein as Wikimedia Commons does for multimedia files. Wikimedia Wikidata wiki uses a dual licensing scheme; quote: "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, raw wikidata was originally used extensively by OmegaWiki.

Wikimedia Foundation, Inc. (WMF), founded 20 June 2003, is the wiki company and non-profit charitable organization[1] responsible for a very large number (over 900 in total) of very active collaborative user-generated wiki sites, which are grouped together by primary subject and known as a 'project'; as well as the wiki engine software initially developed by themselves, known as MediaWiki. The Wikimedia Foundations' major wiki projects started with Wikipedia (encyclopedia), and subsequently expanded to include Wiktionary (dictionary and thesaurus), Wikiquote (quotations), Wikibooks (open content textbooks), Wikisource (free content primary-source 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 site versions written in many different languages. There is also the Wikimedia Commons (shared multilingual repository for documents, images, videos, and other media and text files), and the Wikimedia Meta-Wiki (multilingual coordination of issues common to all Wikimedia projects). The Wikimedia Foundations' global reach is nurtured in its Incubator, where all new language versions for all projects are initiated and developed before being launched as a new separate wiki site. The Foundations' most recent major multi-language wiki project, Wikivoyage (a 'travelpedia'), was inducted to WMF in late 2012 (having being independently established in 2006). Also launched in 2012 was Wikidata (a major multilingual central space knowledge base for structured data used on all WMF projects). The newest WMF project is Wikifunctions, launched in mid 2023, is a library of code functions in many different programming languages.

Wikimedia Foundation, Inc. is a member of the Open Source Initiative (OSI). Furthermore, the Wikimedia Foundation is a United States 501(c)(3) non-profit organization, granted April 2005, and headquartered at 1 Montgomery Street, Suite 1600, San Francisco County, State of California 94104, United States of America.[2]
