Zikula

Zikula is a free and open source modular web application framework written in PHP. The Web Application Framework has a modular structure and is easy to add functionality through third-party modules. It provides an advanced user group permissions system so you can decide who gets access to specific parts of your site. It supports about 36 languages, has an embedded WYSIWYG HTML editor, includes site search and focuses on a high level of security. Some key issues to consider when choosing software are standards. Zikula adheres to W3C standards (XHTML and CSS2), creates accessable output - follows WCAG accessibility guidelines, and has recently been reviewed so the output is search engine optimized. Zikula runs in many environments, including Windows, Mac OS X, Linux, FreeBSD, and any platform supporting either the Apache (version 1.3+), or IIS (version IIS5+) Web server and the PHP language (version 4.1+). Zikula requires a database such as MySQL(4.1+) or PostgreSQL to store content and settings.
