Web Design & Development Guide
Joomla! is a
free, open source content management system written with PHP for publishing
content on the world wide web and intranets, using the MySQL database. Joomla!
includes features such as page caching to
RSS feeds, printable versions of pages, news flashes,
blogs, polls, website searching, and language internationalization. Joomla! is licensed under the
GPL, and is the result of a fork of Mambo.
Joomla! came into being as the result of a fork of Mambo between Miro
Corporation of Australia, the trademark holder of the Mambo name at that time,
and all of the then-core developers. The two groups parted ways on August 17,
2005. The Miro Corporation formed a non-profit foundation with the stated purpose to fund the project and protect it from
The development team claimed that many of the provisions of the foundation
structure went against previous agreements made by the elected Mambo Steering
Committee, lacked the necessary consultation with key stake holders, and
included provisions that violated core
open source values.
The development team created a web site called OpenSourceMatters to
distribute information to users, developers, web designers, and the community in
general. The project team leader at the time
Andrew Eddie, also known as "MasterChief," wrote an open letter to the
which appeared on the announcements section of the public forum at
Open Source Matters logo
One thousand people had joined the opensourcematters.org forum web site
within a day, most posting words of encouragement and support for the actions of
the Development Team. The web site received a
slashdotting and news articles regarding the event appeared at newsforge.com,
eweek.com, and ZDnet.com. Miro CEO Peter Lamont gave a public response in an
article entitled "The Mambo Open Source Controversy - 20 Questions With Miro".
This event has stirred deeply held feelings in the
free software community regarding what shall constitute "open source".
Forums at many other open source projects were active with postings for and
against the actions of both sides. Rumor and accusations of wrongdoing by Miro
and the Mambo Foundation were rampant.
In the two weeks following Eddie's announcement teams were re-organized and
the community continued to grow. On September 1, 2005 the new name, "Joomla!",
which is the English spelling of the Swahili (and Urdu: جملہ) word jumla meaning "all together" or
"as a whole", was announced to a mixed reception of 3000+ faithful followers of
the Development Team. It was chosen to reflect the commitment of the development
team and community to the project.
The first release of Joomla! (Joomla! 1.0.0) was announced on September 16,
2005. This was a re-branded release of Mambo 18.104.22.168 combined with other bug and
moderate-level security fixes. In the project's roadmap, the core developers say
Joomla! 1.5 will be a completely re-written code base built with PHP 5. It was
announced in 2006 and has been nominated for the vaporware award 2007.
Joomla! won the Packt Publishing Open Source Content Management System Award
The Joomla! package consists of many different parts, which are built to be
as modular as possible, allowing extensions and integrations to be made easily.
An example of such are extensions called "Plugins".(Previously
known as "Mambots".) Plugins are background extensions that extend Joomla! with
new functionality. The
WikiBot, for example, allows the author of Joomla! content to use "Wikitags"
in Joomla! articles which will auto-create dynamic hyperlinks to Wikipedia
articles when displayed. There are over 1,900 extensions for Joomla! available
Extensions Directory, a site that OpenSourceMatters runs as an official
directory of extensions.
In addition to Plugins, more comprehensive extensions are available.
"Components" allow webmasters to perform such tasks as build a community by
expanding user features, backup a website, and create URLS that are more
friendly to search engines.
"Modules" perform such tasks as displaying a calendar or allowing custom code to
be inserted within the base Joomla! code.
Joomla! has an official and many unofficial communities. As of July 2007, the
official Joomla! forums claims 178,000 threads and over 920,000 posts from over
120,000 members in 40 languages.
Unofficial sites are published in many languages, often with Joomla! extensions
that are region specific. Bi-directional text support for the Hebrew and Arabic
languages, for example, can be found on 3rd party community portals. Unofficial
web developers also build extensions and web templates for commercial sale and
