WSMX Deliverable D 10 v 0 . 2 Semantic Web

Semantic web services promise to add automation and dynamics to current web service technologies, considerably reducing the effort required to integrate applications, businesses and customers. One of the key tasks in the integration process is to locate services that can fulfill the application, business or customer needs. With current web service technologies, this is done mainly manually, which reduces the accuracy of the search and requires considerable effort. Semantic web services aim at providing formal descriptions of requests and web services that can be exploited to automate several tasks in the web services usage process, including dynamic discovery of services. WSMO discovery provides a conceptual model for service discovery that exploits WSMO formal descriptions of goals and web services. In this document, and based on the theoretical foundations provided by WSMO and WSMO discovery, we investigate the implementation of a discovery engine that can provide dynamic web service discovery. We focus on the language requirements to formalize WSMO goals and web service capabilities, on the integration of different approaches to web service discovery defined by WSMO discovery, and on the definition of the interface and architecture of the discovery engine.
