A Semantic-Based Web Service Composition Facility for ebXML Registries

Web services have become a main thrust of the IT industry and there has been considerable development in this area. There are two almost universally accepted standards: SOAP (Simple Object Access Protocol) for invoking services and WSDL (Web Services Description Language) for describing the technical specifications of the services. There are well-established service registries like UDDI (Universal Description, Discovery and Integration) by Microsoft and IBM, and ebXML (electronic business XML) by UN/CEFACT. The infrastructures for Web services are also readily available through application servers like IBM’s WebSphere, Microsoft’s .NET Framework or BEA’s Weblogic. All of these application servers provide support for SOAP, WSDL and UDDI connectivity. However to be able to employ the full potential of Web services, their semantic information should be exploited. In this paper we describe a service composition tool which, by using the semantic information stored in ebXML registries, helps to automate the service discovery and composition.
