WikipediaWikipedia is a free-content online encyclopedia written and maintained by a community of volunteers, collectively known as Wikipedians, through open collaboration and using a wiki-based editing system called MediaWiki. Wikipedia is the largest and most-read reference work in history, and has consistently been one of the 10 most popular websites. Created by Jimmy Wales and Larry Sanger on January 15, 2001, it is hosted by the Wikimedia Foundation, an American nonprofit organization.
Wikimedia FoundationThe Wikimedia Foundation, Inc. (WMF) is an American 501(c)(3) nonprofit organization headquartered in San Francisco, California, and registered as a charitable foundation under local laws. Best known as the hosting platform for Wikipedia, a crowdsourced online encyclopedia, it also hosts other related projects and MediaWiki, a wiki software. The Wikimedia Foundation was established in 2003 in St. Petersburg, Florida, by Jimmy Wales as a nonprofit way to fund Wikipedia, Wiktionary, and other crowdsourced wiki projects that had until then been hosted by Bomis, Wales's for-profit company.
Aaron SwartzAaron Hillel Swartz (November 8, 1986January 11, 2013) was an American computer programmer, entrepreneur, writer, political organizer, and Internet hacktivist. As a programmer, Swartz helped develop the web feed format RSS; the technical architecture for Creative Commons, an organization dedicated to creating copyright licenses; the website framework web.py; and Markdown, a lightweight markup language format. Swartz was involved in the development of the social news aggregation website Reddit until he departed from the company in 2007.
English WikipediaThe English Wikipedia is the primary English-language edition of Wikipedia, an online encyclopedia. It was created by Jimmy Wales and Larry Sanger on January 15, 2001, as Wikipedia's first edition. English Wikipedia is hosted alongside other language editions by the Wikimedia Foundation, an American non-profit organization. Its content is written independently of other editions in various varieties of English, aiming to stay consistent within articles. Its internal newspaper is The Signpost.
WiktionaryWiktionary (UKˈwɪkʃənəri, ; USˈwɪkʃənɛri, ; rhyming with "dictionary") is a multilingual, web-based project to create a free content dictionary of terms (including words, phrases, proverbs, linguistic reconstructions, etc.) in all natural languages and in a number of artificial languages. These entries may contain definitions, s for illustration, pronunciations, etymologies, inflections, usage examples, quotations, related terms, and translations of terms into other languages, among other features.
WikinewsWikinews is a free-content news wiki and a project of the Wikimedia Foundation that works through collaborative journalism. Wikipedia co-founder 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. In contrast to most Wikimedia Foundation projects, Wikinews allows original work in the form of original reporting and interviews.
WikisourceWikisource is an online digital library of free-content textual sources on a wiki, operated by the Wikimedia Foundation. Wikisource is the name of the project as a whole and the name for each instance of that project (each instance usually representing a different language); multiple Wikisources make up the overall project of Wikisource. The project's aim is to host all forms of free text, in many languages, and translations.
Wikimedia CommonsWikimedia Commons (or simply Commons) is a media repository of free-to-use images, sounds, videos and other media. It is a project of the Wikimedia Foundation. Files from Wikimedia Commons can be used across all of the Wikimedia projects in all languages, including Wikipedia, Wikivoyage, Wikisource, Wikiquote, Wiktionary, Wikinews, Wikibooks, and Wikispecies, or downloaded for offsite use. As of February 2023, the repository contains over 90 million free-to-use media files, managed and editable by registered volunteers.
Wikipedia communityThe Wikipedia community, collectively and individually known as Wikipedians, is an online community that volunteers to create and maintain Wikipedia, an online encyclopedia. Since August 2012, the word "Wikipedian" has been an Oxford Dictionary entry. Wikipedians may consider themselves part of the Wikimedia movement, a global network of volunteer contributors to Wikipedia and other related projects hosted by the Wikimedia Foundation.
