'''MediaWiki''' is the name for the Wiki engine that runs the [[http://wikipedia.org/|Wikipedia]] and other Wikimedia projects!

Wikipedia was previously using UseMod as its WikiEngine, hence MediaWiki is largely derived from UseMod, with specific enhancements focused on scalability, like a SQL backend, output caching and section editing. Its !MediaWikiText markup is very similiar to UseMod's markup.

Its project homepage is at http://mediawiki.org/ and it is discussed also at http://meta.wikimedia.org/wiki/MediaWiki.

For similarities/differences with MoinMoin, see MoinMoinVsMediaWiki and WikiEngineComparison, [[http://meta.wikimedia.org/wiki/MediaWiki_feature_list|MediaWiki feature list]] and [[http://meta.wikimedia.org/wiki/MediaWiki_reviews|MediaWiki reviews]].

 . "''MediaWiki is primarily targeted at Wikipedia and Wikimedia's other projects (and other similar large-scale sites with people running their own servers), secondarily at people running local instances to work with data from our sites, and only incidentally at anyone else.''" -- Brion Vibber (MediaWiki developer)

== MediaWiki plugin ==
There is a MediaWiki plugin (parser) for MoinMoin named "media4moin" that makes Moin compatible. You can download it at ParserMarket. It enables you to use most of MediaWiki`s markup, but some (like InterWiki support) is missing.

Other resources for moving from one engine to the other are listed on the [[http://www.mediawiki.org/wiki/MoinMoin|mediawiki.org page on MoinMoin]].
