摘要: In this paper we describe our experience in applying KAoS services to ensure policy compliance for Semantic Web Services workflow composition and enactment. We are developing these capabilities within the context of two applications: Coalition Search Rescue (CoSAR-TS) Firewall (SFW). how work has uncovered requirements increasing expressivity beyond what can be done with description logic (e.g., role-value-maps), extending representation reasoning mechanisms a carefully controlled manner that end. Since employs OWL representation, it fits naturally use OWL-S descriptions generated by AIAI I-X planning system CoSAR-TS application. The advanced based on JTP inference engine enable analysis classes instances processes from perspective. As result analysis, concludes whether particular step is allowed performance would incur additional policy-generated obligations. Issues described. Besides during composition, aspects checked at runtime when enacted. illustrate through application examples. Finally, outline plans future work.
