SEMANTIC SERVICE DESCRIPTION TO SUPPORT EDUCATION AND TRAINING - An Easy-to-Apply Service Description Model and Service Registry

This work describes a semantic service description model based on and inspired by existing service description approaches like WSDL-S and OWL-S and a service registry to support the creation of service oriented applications in the area of education and training. Our service description is based on an OWL ontology and combines a simple messageand state-oriented approach in order to reduce the effort for the creation of the descriptions which is a major drawback of a lot of existing, powerful semantic service description approaches. Furthermore, the proposed service description enables the matchmaking algorithm of the service registry to use not only the data-oriented input and output parameters to identify suitable services but also considers the preconditions and effects of a service. The usage of the service description model and the search capabilities are discussed against the background of the education and training area.
