Abstract
Web service composition through declarative queries was described. Executability depends on the specific syntactic form of query while feasibility is a more robust semantic notion involving all equivalent queries. An algorithm was also presented to compute complete answers to queries that are not feasible. It was emphasized that the costly containment check should be avoided by using two efficiently computable approximate execution plans.
