Service-oriented Computing has recently received a lot of attention from both academia and industry. However, current service oriented solutions are often not as dynamic and adaptable as intended because the publish-find-bind-execute cycle of the SOA triangle is not entirely realized. In this paper, the authors highlight some issues of current Web service technologies, with a special emphasis on service metadata, querying, invocation and mediation. They present the Vienna Runtime Environment for Service-oriented Computing (VRESCo) that aims at solving a number of these issues. Among others, VRESCO provides support for service metadata and querying, monitoring of Quality of Service, dynamic binding and invocation including service mediation, service notifications, and service compositions.
