  Our works aim at developing a Web platform to connect various Communities of
Practice (CoPs) and to capitalise on all their knowledge. This platform
addresses CoPs interested in a same general activity, for example tutoring. For
that purpose, we propose a general model of Interconnection of Communities of
Practice (ICP), based on the concept of Constellation of Practice (CCP)
developed by Wenger (1998). The model of ICP was implemented and has been used
to develop the TE-Cap 2 platform which has, as its field of application,
educational tutoring activities. In particular, we propose an indexation and
search tool for the ICP knowledge base. The TE-Cap 2 platform has been used in
real conditions. We present the main results of this descriptive investigation
to validate this work.
