The modeling of the process is a key point for the successful use of collaborative project-based learning environments. We built a cooperation model expressed as patterns in order to point out these ideas. In this paper, we describe the scenario chosen to evaluate the model: collaborative writing projects and EdiTex, a groupware tool to support them. We tested our ideas by using EdiTex in two c...

We address the problem of consistency of replicated wiki pages in the context of a P2P Wiki system. In this paper,...
