Symphony CMS - XSLT powered CMS

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.

A project's content types are defined using sections and fields. Its pages provide dynamic front-end interfaces for viewing and interacting with that content. Data sources fetch and organize the content and deliver it to pages as XML, where page templates and utilities are applied to transform it into a desired format (HTML, for example). Advanced interactions, like data submission, can be enabled using events.

You will need to design your own data models, thinking carefully about the structure of your content and how different types relate to one another. You will have to draw up an architecture and URL schema for your front end. And you'll need to map out how you want your content to flow through the system.
