Abstract:

In this paper,knowledge sharing is realized by the same distributed vocabulary, which is utilized by the ontology based on description logic in different systems. It leads to the unification of the roles and authorities in multi- autonomy domains. Besides, because the mutual exclusion of roles is one   of systems, we achieve the ontological mutual exclusion of roles by the most important restrictions in role-based access control the grammar of descript  ion logic.

Key words:  （role-based access control, ontology, mutual exclusion of roles, description logical）
