I'm currently looking for an Open Source PHP\mySQL CMS product that allows the creation of custom content types, or allows you add custom metadata to the content type.
Somethink like umbraco, where you can create your own document types, and then add styles onto that content... using styling tags... Rather than just "Articles" or pages.
IE: I can create a content type in my tree, and that content type has specific meta fields on them. IE: List of software, I could have Name, Link, Description, Image etc...
I am aware of Drupal, but having worked with that previously, i dont really like it.
