Wikimedia Foundation

The Wikimedia Foundation is a nonprofit organization that hosts Wikipedia and operates other free-knowledge projects, including Wikimedia Commons and Wikidata.

Wikimedia projects: A family of collaborative free-knowledge projects hosted or supported by the Wikimedia Foundation. The Foundation provides the shared infrastructure and support behind this project family.
Wikipedia: A free online encyclopedia written and maintained by volunteers. Wikipedia is the Foundation’s best-known project and its largest public-facing service.
Jimmy Wales: An American internet entrepreneur who co-founded Wikipedia and the Wikimedia Foundation. Wales helped establish the Foundation to support Wikipedia and related projects.
Wikimedia community: The volunteers and other contributors who create, edit, and govern Wikimedia project content. The Foundation hosts the projects, while communities largely determine their content and editorial practices.
Wikimedia servers: The computing systems that store and deliver Wikimedia websites and their data. The Foundation operates the infrastructure that keeps its projects available worldwide.
Wikimedia Commons: An online repository of freely licensed media files and public-domain works. The Foundation hosts this shared media library for use across Wikimedia projects.
Wikipedia launch: The January 2001 launch of Wikipedia as a collaboratively edited online encyclopedia. Wikipedia’s rapid growth created the need for an organization to sustain its infrastructure.
Wikimedia chapters: Independent nonprofit organizations affiliated with the Wikimedia movement in particular regions. Chapters are separate legal entities, unlike the central Foundation that hosts the websites.
Wikimedia movement: A global community and network of organizations working to make free knowledge available. The Foundation is one institution within a broader movement that includes volunteers and affiliates.
Wikidata: A collaborative knowledge base of structured data readable by people and machines. The Foundation supports this project as a reusable source of linked facts.
