Modeling and Managing Collaborative Sessions for a Virtual Organization

We propose a system that allows users to engage in collaborative sessions through a variety of communication tools running simultaneously. In this paper we use description logic to model a broad range of features of a proposed session and we validate it before it is invoked, by checking for consistency with constraints arising from three main areas. We ensure (a) that it will not exceed the capacity of the network given the bandwidth consumed by sessions that are currently running, (b) that it does not violate any of the physical limitations of the resources to be invoked, and (c) that the participants possess the expertise required to contribute to the session.
