Abstract
The automatic location of services that fulfill a given need is recognized as a key step towards dynamic and scalable integration. In order to achieve such automation, a model that considers the dynamic aspects of service provision and how they affect service descriptions, and that enables an efficient and accurate discovery and contracting of relevant services, is required. In this paper we propose such a model, paying special attention to the distinction between services and Web services and how these two concepts relate to each other. The border between Web service discovery and service contracting is discussed, and what kind of descriptions can be expected at each step is analyzed. We outline requirements on frameworks for semantic description of Web Services in the light of our model, and propose techniques for realizing the dicovery and contracting steps.
