Abstract
In the semantic web environment it is important to be able to specify access control requirements about subjects accessing the information and about resources to be accessed in terms of the rich ontology-based metadata describing them. In this paper, we outline how current standard policy languages such as XACML can be extended to address this issue. Then, we describe a reference architecture for enforcing our semantics-aware policies.
