Still in beta at time of writing, Ariadne is a Web application framework from Muze, a development agency in the Netherlands. It's available under the GNU Public License. Auke van Slooten leads the project. The source code can be downloaded from the Muze site <http://www.muze.nl/software/ariadne/ >.
Ariadne stores PHP source code as objects in a MySQL database. These objects interact with each other using a virtual file system. A rich user interface is presented to the user through Web pages, but advanced users may dig deeper, as well. Another major component controls access rights for users or groups.
