Abstract

KAoS policy and domain services help with policy specification, analysis, disclosure, and enforcement of policies for Semantic Web Services. The authors describe these capabilities in the context of three example applications: Grid Policy Management, Coalition Search and Rescue and the Semantic Firewall. This has uncovered requirements for increasing the policy's expressivity beyond what you can do with description logic (for example, role-value maps). As the result of analysis, KAoS concludes whether policy allows a particular workflow step and whether the performing this step would incur additional policy-generated obligations. The authors also discuss issues in representing processes in OWL-S.
