Joomla Content Management System

Joomla is a free and open-source content management system (CMS) for publishing web content, built on the Model-View-Controller (MVC) web application framework. Released in 2005 as a fork of Mambo (which was developed by Miro International), Joomla was created by the core development team that left Mambo over disagreements about the project's open-source governance. The name is a phonetic spelling of the Swahili word jumla, meaning all together or as a whole. Headquartered in New York City, the project is maintained by Open Source Matters, Inc., a non-profit organization. Key features: content management: create and organize articles, categories, and tags with a built-in WYSIWYG editor (TinyMCE). Content versioning tracks changes and allows rollback. Workflow management with stages and transitions for editorial processes. Template system: separate presentation from content using MVC. Templates control the visual design using HTML, CSS, and PHP overrides. Thousands of free and commercial templates are available. Extension ecosystem: over 8,000 extensions categorized into components (full applications), modules (display widgets), plugins (event handlers), and templates. Popular extensions include VirtueMart (e-commerce), Community Builder (social networking), K2 (advanced content), and Akeeba Backup. Multi-language: built-in multilingual support for over 75 languages. Create content in multiple languages and let visitors switch between them. User management: granular access control with user groups, viewing access levels, and permissions. ACL (Access Control List) system allows fine-grained control over who can view, edit, and manage content. SEO: search engine friendly URLs, metadata management, and redirects. Media manager: upload, organize, and manage images and files. Menu system: create hierarchical menus with custom module assignments. Database: MySQL, MariaDB, or PostgreSQL. PHP-based. GPL-2.0.
