Wikipedia
Wikipedia is a multilingual free online encyclopedia written and maintained by a community of volunteers, known as Wikipedians, through open collaboration and using a wiki-based editing system. Wikipedia is the largest and most-read reference work in history. It is consistently one of the 10 most popular websites ranked by Similarweb and formerly Alexa; Wikipedia was ranked the 5th most popular site in the world. It is hosted by the Wikimedia Foundation, an American non-profit organization funded mainly through donations. Wikipedia was launched by Jimmy Wales and Larry Sanger on January 15, 2001. Sanger coined its name as a blend of ''wiki'' and '' encyclopedia''. Wales was influenced by the " spontaneous order" ideas associated with Friedrich Hayek and the Austrian School of economics after being exposed to these ideas by the libertarian economist Mark Thornton. Initially available only in English, versions in other languages were quickly developed. Its combin ...

Wikivoyage
Wikivoyage is a free web-based travel guide for travel destinations and travel topics written by volunteer authors. It is a sister project of Wikipedia and supported and hosted by the same non-profit Wikimedia Foundation (WMF). Wikivoyage has been called the "Wikipedia of travel guides". The project began when editors at the German and then Italian versions of Wikitravel decided in September 2006 to move their editing activities and then current content to a new site, in accordance with the site copyright license, a procedure known as " forking". The resulting site went live as "Wikivoyage" on December 10, 2006, and was owned and operated by a German association set up for that purpose, Wikivoyage e.V. (which continues to be its representative association). Content was published under the copyleft license Creative Commons Attribution-ShareAlike. In 2012, after a long history of problems with their existing host,

Wikidata
Wikidata is a collaboratively edited multilingual knowledge graph hosted by the Wikimedia Foundation. It is a common source of open data that Wikimedia projects such as Wikipedia, and anyone else, can use under the CC0 public domain license. Wikidata is a wiki powered by the software MediaWiki, and is also powered by the set of knowledge graph MediaWiki extensions known as Wikibase. Concept Wikidata is a document-oriented database, focused on items, which represent any kind of topic, concept, or object. Each item is allocated a unique, persistent identifier, a positive integer prefixed with the upper-case letter Q, known as a "QID". This enables the basic information required to identify the topic that the item covers to be translated without favouring any language. Examples of items include , , , , and . Item labels need not be unique. For example, there are two items named "Elvis Presley": , which represents the American singer and actor, and , which represents h ...

Wikinews
Wikinews is a free-content news wiki and a project of the Wikimedia Foundation that works through collaborative journalism. Wikipedia cofounder Jimmy Wales has distinguished Wikinews from Wikipedia by saying, "On Wikinews, each story is to be written as a news story as opposed to an encyclopedia article." Wikinews's neutral point of view policy aims to distinguish it from other citizen journalism efforts such as Indymedia and OhmyNews.
