The role transition mechanisms in role-based collaborative system

This paper introduces the basic concepts and processes of role-based collaboration and the basic components of role-based collaborative systems including roles, agents and groups. It mainly describes our implementation of the role specification and transition mechanisms. In this prototype, we compose a role as a set of rights to access resources and a set of responsibilities to serve others. We conclude that these mechanisms are a maintainable, extensible framework to create more collaborative systems in the future
