Publishing intentional services using extended semantic annotation

With the increasing growth in popularity of Web services, it is still difficult for business users to fully benefit from the SOA if it remains at the software level. The introduction of intentional services has been proposed to bridge the gap between low level, technical software-service descriptions and high level, strategic expressions of business needs for services. This proposal leverages on the SOA to an intentional level, and introduces the iSOA architecture. As current Web services technology based on UDDI and WSDL does not make use of this “intention” and therefore fails to address the problem of matching between capabilities of services and business user needs, we are interested in this work in extending existing approaches for the description of intentional services. Our proposed approach is an extension of the W3C recommendation on semantic annotation for Web services (SAWSDL). The semantic annotations added to the descriptor are based on intentional service ontology. This ontology is built upon the intentional service model and the goal model; it contains all necessary concepts for defining the goal and the intentional service. We introduce the intentional service descriptor to be published in an extended registry, and illustrate our work with an example.
