AWS-Ont: An Ontology for the Self-Management of Service-Based Systems

With the increasing complexity of Web service management in highly dynamic environments, service providers must participate to the self-adaptation process as they are aware of the capabilities and requirements of their executing services. However, defining additional adaptation policies demands a greater effort. A primary condition to reuse other providers´ policies is to understand the information specifying a service behavior. Despite several efforts, a common self-management syntax and semantic was not achieved. In this paper, we propose an ontology-based categorization of autonomic service metadata, which will be used not only for policy discovery and integration, but also for the composition of self-adaptive Web services. We, then, propose to semantically annotate providers´ policies. This allows providers to discover and reuse policies based on their semantic meaning. Finally, we propose a framework for the discovery, matching, and integration of providers´ policies.
