KAoS policy and domain services: toward a description-logic approach to policy representation, deconfliction, and enforcement

We describe our initial implementation of the KAoS policy and domain services. While primarily oriented to the dynamic and complex requirements of software agent applications, the services are also being adapted to general-purpose grid computing and Web services environments as well. The KAoS services rely on a DAML description-logic-based ontology of the computational environment, application context, and the policies themselves that enables runtime extensibility and adaptability of the system, as well as the ability to analyze policies relating to entities described at different levels of abstraction.
