Differences between Wikipedia, Wikimedia, MediaWiki, and wiki/zh

搞不懂 MediaWiki、Wikimedia、Wikipedia 和 wiki 的区别？

Wiki
A wiki is a type of website whose contents can be edited from the web browser, and which keeps a version history for each editable page. Wikis are often, but not always, editable by any visitor to the site.


 * wiki（作为形容词）、“wiki 方式”和反义词 un-wiki 也表示使用这种系统的面向社群哲理（例如“那不是很 wiki 做事方式”）.


 * Wiki（'W' 大写）是错误的术语，尽管有时被用于引用维基百科或 波特兰模式知识库（也称为 WikiWikiWeb），这是创建的第一个 wiki.


 * wiki software and wiki engine are terms referring to pieces of software that power wiki websites. There are many different types of wiki software; some very simple, others with advanced features.

Wikimedia
Wikimedia 是维基活动中一系列内在相关计划的集合名词，包括维基媒体、维基词典、维基名言及其他，这些计划通过互联网强大的协作能力和 wiki 理念致力于创建和分享各种类别的自由知识.


 * 维基媒体服务器术语一般指托管所有维基媒体计划的计算机硬件.
 * Wikimedia Foundation is a non-profit organization headquartered in San Francisco that runs the Wikimedia projects. Wikimedia Deutschland, Wikimedia Russia etc. are the names of dozens of local chapters of enthusiasts of Wikimedia projects. They are independent from the Wikimedia Foundation and the Wikimedia projects. Wikimedia, depending on the context and locale, is often incorrectly used as short name for the Wikimedia projects, or a chapter, or the Wikimedia Foundation (the latter can happen also on this wiki).
 * Wikimedia Meta-Wiki 通常也写成 Meta，是用来讨论与所有维基媒体计划有关问题的 wiki. 另请参阅 About. 
 * Meta 应该不会和MetaWiki 混在一起，后者是与维基媒体系列计划无关的搜索引擎.

Wikipedia
Wikipedia 是提供全球、自由、多语的互联网百科全书的维基媒体计划. 这是最古老、最宏大且早于维基媒体基金会的维基媒体计划. 维基百科是运行 MediaWiki 的 wiki.

MediaWiki
MediaWiki is a particular wiki engine, that is developed for and used by Wikipedia and the other Wikimedia projects. MediaWiki is freely available for others to use (and improve), and it is in use by all sorts of projects and organizations around the world.

This site, mediawiki.org, is intended for information about MediaWiki and related software.
