Wikipedia is a project of the Wikimedia Foundation, and features content created by volunteers from around the world.

Our mission

Imagine a world in which every single human being can freely share in the sum of all knowledge.

Participation

Wikipedia, like all Wikimedia projects, is founded on a principle of open participation. We don't merely provide an encyclopedia that is free to read and reuse; we provide it on a platform that permits anyone with Internet access to build the encyclopedia. The software developed to support Wikipedia, MediaWiki, is available under a free license, and is continually improved through the efforts of thousands(?) of volunteers. It is designed in a way that supports tens of thousands of individuals to improve Wikipedia, without even needing to create an account, or provide any more personal information than they wish to. Wikipedia also has numerous formal and informal programs, mostly volunteer-led, that help new contributors learn to edit the site and build community around our shared project. Decisions are generally made on a consensus-based model in which anyone may participate in deliberation. Openness is a one of Wikipedia's core values. Even the rules governing Wikipedia are open to improvement, and have been refined and improved over the years by a variety of volunteers and project participants.

Wikipedia wants you to participate in its vision of freely shared knowledge.

Our datasets

We also publish metadata about our articles, templates and categories, how they are viewed, and how they are edited.

Third parties

Some third parties use or database dumps to offer extra datasets or services. For example:
