A Semantically Enhanced Service Repository for Service Oriented Application System Development

Currently a large numbers of Web services as well as other kinds of services such as EJBs, COM, and even Java classes are published both externally and internally to an organization. Enabling SOA based system development by leveraging such kinds of services becomes a challenge. A semantically enhanced service repository which includes a service registry and a semantic service repository is put forward in this paper.The service registry manages the Web services, EJBs, and Java Classes by facilitating service registration,publishing, versioning, and monitoring. The details of the service model used in the registry are analyzed. Then the semantic service repository encapsulating the services with OWL-S is proposed. Later the ontology-based service discovery and matching method are introduced.The repository proposed in this paper can be used to manage the services and facilitate the service oriented application system development and integration.
