From Web Service Policies to Automatic Deviation Handling: Supporting Semantic Description of Reactions to Policy Violations

In scenarios where Web services are involved, Quality of Service (QoS) parameters play an important role when it comes to service selection, service compositions, and run-time behavior of the execution environment, e.g. a workflow engine. Required or guaranteed QoS levels are often described by means of Web service policies. However, policy languages do usually not include the handling of deviations respectively reactions. In this paper, we introduce WS-Re2Policy 2.0, a semantic extension of our former work on a policy language which makes use of WS-Policy in order to describe requirements and handling of deviations through defined reactions. Furthermore, we present a basic ontology for reactions which we make use of in order to semantically annotate reactions in WS-Re2Policy 2.0.
