This will be seeing some life in the next few months.
The Rubric module is an educationally focused module that is a plug-in for the Assignment Studio project. The two together will allow end users to assess the other users of the site (of a certain role(s)). It allows for the creation of a taxonomy which is used as "assignments" and then the association of a rubric to each assignment. One rubric can be reused many times and associated with many different assignments. Different components of the rubric will be reusable in and of itself. Criteria (rows), Categories (groups of rows) and entire rubrics can be replicated and reused in part of in whole within other rubrics. Web 2.0 tools have been constructed to make the creation of rubrics very simple as well as the association with an assignment / taxonomy term.
This will hook into the assignment studio so that you can quickly run through a list of all users defined as students and assess them rapidly. Check out my youTube channel as it's full of screencasts of the development of the module http://www.youtube.com/user/btopro
