OntoRBAC: Specify and Integrate RBAC Policies with Ontologies
OntoRBAC：基于本体的RBAC策略描述与集成

Policies are becoming an increasingly popular approach to access control systems of applications in academia and industry.As information pertaining to different policies has varying access control requirements,in this paper,we propose the definition of OntoRBAC,an ontology of a general RBAC policy.Supporting and extending the RBAC96 model,it helps to specify role-based access control policies more accurately for the powerful expressive ability.It also provides more effective ways to integrate other policies in the semantic level.Some rules in form of SWRL have been defined to reason within the OntoRBAC.At last,the architecture of implementation is discussed.
