Joomla is a free and open-source content management system (CMS) for publishing web content. It is built on a model–view–controller web application framework that can be used independently of the CMS. Joomla is written in PHP, uses object-oriented programming (OOP) techniques (since version 1.5〔(Introduction for developing a Model-View-Controller Joomla 1.5 Component )〕) and software design patterns,〔(The Case for Better Architecture )〕 stores data in a MySQL, MS SQL (since version 2.5), or PostgreSQL (since version 3.0) database,〔(New Features in Joomla! 2.5 | Joomla! Community Portal )〕〔() Joomla 3〕 and includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, search, and support for language internationalization. , Joomla has been downloaded over 50 million times.〔(Joomla! CMS Passes 50 Million Downloads )〕 Over 7,700 free and commercial extensions are available from the official Joomla! Extension Directory, and more are available from other sources. It is estimated to be the second most used content management system on the Internet, after WordPress.〔(Usage Statistics and Market Share of Content Management Systems for Websites, October 2014 )〕 == History == Joomla was the result of a fork of Mambo on August 17, 2005. At that time, the Mambo name was a trademark of Miro International Pty Ltd, who formed a non-profit foundation with the stated purpose of funding the project and protecting it from lawsuits.〔(【引用サイトリンク】title=Mambo Foundation Web site, Goals and objectives )〕 The Joomla development team claimed that many of the provisions of the foundation structure violated previous agreements made by the elected Mambo Steering Committee, lacked the necessary consultation with key stakeholders and included provisions that violated core open source values.〔(【引用サイトリンク】title=Joomla Forum Discussion by Development Team members and Community )〕 Joomla developers created a website called OpenSourceMatters.org (OSM) to distribute information to the software community. Project leader Andrew Eddie wrote a letter that appeared on the announcements section of the public forum at mamboserver.com. Over one thousand people joined OpenSourceMatters.org within a day, most posting words of encouragement and support. The website received the Slashdot effect as a result. Miro CEO Peter Lamont responded publicly to the development team in an article titled "The Mambo Open Source Controversy — 20 Questions With Miro". This event created controversy within the free software community about the definition of ''open source''. Forums of other open-source projects were active with postings about the actions of both sides. In the two weeks following Eddie's announcement, teams were re-organized and the community continued to grow. Eben Moglen and the Software Freedom Law Center (SFLC) assisted the Joomla core team beginning in August 2005, as indicated by Moglen's blog entry from that date and a related OSM announcement. The SFLC continue to provide legal guidance to the Joomla project.〔(【引用サイトリンク】title=Partners )〕 On August 18, Andrew Eddie called for community input to suggest a name for the project. The core team reserved the right for the final naming decision, and chose a name not suggested by the community. On September 22, the new name, ''Joomla!,'' was announced. It is the anglicised spelling of the Swahili word meaning ''all together'' or ''as a whole''〔("Joomla!" ). Open Source Matters.〕 which also has a similar meaning in at least Amharic, Arabic and Urdu. On September 26, the development team called for logo submissions from the community and invited the community to vote on the logo; the team announced the community's decision on September 29. On October 2, brand guidelines, a brand manual, and a set of logo resources were published.〔(【引用サイトリンク】Logo Usage and Brand Guide )〕 Joomla won the Packt Publishing Open Source Content Management System Award in 2006, 2007, and 2011. On October 27, 2008, PACKT Publishing announced that Johan Janssens was the ''Most Valued Person'' (MVP), for his work as one of the lead developers of the 1.5 Joomla Framework and Architecture. In 2009 Louis Landry received the ''Most Valued Person'' award for his role as Joomla architect and development coordinators 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Joomla」の詳細全文を読む スポンサード リンク
