The term policy encompasses different notions like, among others, security policies, trust management policies, business rules and quality of service specifications. Researchers have mainly focuses in one or more contexts separately but not on a broader view. In addition, in web applications, policies are pervasive and they play crucial roles in enhancing security, privacy, but also service usability. Interoperability and self-describing semantics become key requirements and there is where Semantic Web comes into play. This tutorial aims at providing an overall view of state of the art (requirements for a policy framework, existing policy frameworks/languages, policy negotiation, context awareness, etc.) as well as open research issues in the area (understanding of policies in their broad sense, integration of trust management, increasement of system cooperation, user-awareness, etc.) required to develop a successful Semantic Policy Framework.
