Web services constitute one of the hot areas in web technology supporting the remote invocation of business functionality over the Internet through message exchange. Marketers are pushing Web Services as the future way of providing value-added services over the internet. Despite the current proliferation of web services, most are for one-way data retrieval or update. While useful, they do not provide the critical components of B2B systems. The complex issues surrounding B2B integration are well documented and no software infrastructure currently exists enabling web services to provide the solution.

 

WSMO focuses on Semantic Web Services by providing a comprehensive ontology describing various aspects of web service technologies. It embodies a world-wide standard initiative, jointly undertaken by DERI, industrial partners and other research groups involved in the EU projects – DIP, SEKT, Knowledge Web, and SWWS. Several tools are being developed around WSMO including an inference-based web service discovery mechanism, an editor for WSMO component descriptions, and a registry for WSMO components. A key aspect of WSMO is the parallel development of WSMX, a reference implementation. Once defined using WSMO, WSMX will manage the tasks of dynamic discovery, mediation, choreography, orchestration and invocation associated with the execution of an integration task. Internally the execution semantics of WSMX provide the reliability, security and trust required of industrial B2B integration systems.

 

Tutorial attendees will learn about the concepts underlying Semantic Web Services. Using hands-on sessions with concrete examples, they will gain the skills to successfully and efficiently use WSMO.
