Shared-Repository based Approach for Storing and Discovering web Services

The Web services technology uses a set of standards, namely SOAP, WSDL and UDDI. In particular, UDDI is a platform for storing and retrieving Web services. Thus, the problem of Web service discovery is often attached to the UDDI. As Web services are developed through Internet, users must be able to effectively access and share these services. The production and interoperability of a large number of Web services has led to the emergence of new standards of publication, discovery and use of Web services. Therefore, mechanisms to distribute services are necessary for efficient selection of the appropriate Web service to the customer needs. In this paper, we propose a shared repository (ontology), which can be exploited by the UDDI for the storage and the discovery of a Web service. A matching algorithm is also proposed to show how to perform this operation. A prototype tool has been developed and experiments have been carried out to evaluate and show the efficiency of our approach.
