The increasing availability of Web services asked for investigating ways to automate the discovery process. Discovery processes enhanced with semantics can be recognize to be general, but often they ...lack the flexibility needed in specific domains. In this paper, we propose the flexible architecture of the discovery engine Glue2, which comes with a powerful set of discovery components (for functional matching, non-functional matching, data fetching, etc.) that can be executed in different order as required by specific execution workflows.
In this paper we describe the improvements on our approach to the old discovery scenario of the SWS Challenge and our current solution for the new discovery and composition scenario. The mediation ...scenario is not included in this paper since there were no changes to it from the edition of the SWS Challenge workshop in Athens. The solution proposed is based on the WebML design methodology and the Glue WSMO discovery engine.
