TL;DR: The experience in applying KAoS services to ensure policy compliance for Semantic Web Services workflow composition and enactment is described and how this work has uncovered requirements for increasing the expressivity of policy beyond what can be done with description logic is described.

TL;DR: Agents will increasingly use the combination of semantic markup languages and Semantic Web Services to understand and autonomously manipulate Web content in significant ways and rely on policy-based management and control mechanisms to ensure respect for human-imposed constraints on agent interaction.

TL;DR: Results, issues, and lessons learned in the development of KAoS representations, tools, and services and their use in military and space application are discussed.

TL;DR: This paper describes how these applications have motivated the partitioning of components into a well-defined three-layer policy management architecture that hides ontology complexity from the human user and from the policy-governed system.

TL;DR: KAoS, a policy and domain services framework based on W3C’s OWL ontology language, is introduced, which enables the specification and enforcement of both authorization and obligation policies.
