Symphony is a web-based content management system (CMS) that enables users to create and manage websites and web applications of all shapes and sizes—from the simplest of blogs to bustling news sites and feature-packed social networks. With Symphony, you can build just about anything, and that's what sets it apart from most other CMSs. Instead of making all kinds of assumptions about your content and what you'll be doing with it, Symphony gives you the tools to make those decisions for yourself. From its very beginning, Symphony has been engineered around principles like openness, simplicity, and standards-compliance. This approach has resulted in a granular architecture that's easy to customize at every level, and a clean, minimal core that's high on efficiency and low on bloat. It's also led to the adoption of open standards like XML and XSLT, which make the system more transparent and free it from constraints common to other CMSs.
