I've been developing Curriculum Central, an application that will provide a catalog of courses offered by a Faculty. The course outlines are managed through a workflow. It also offers "course maps", so that you are able to view requisites for a specific course. I've finished the development work, and am in the process of writing up the developer and user documentation.
do you have a demo site? I assume curriculum central does not work together with dotlrn catalog, right? What can a student on course level? Can he join?
