Abstract Despite all standardization efforts in the Web service area, several different incompatible Web service registry implementations exist. The initial focus of these implementations was geared towards working with a centralized Universal Business Registry (UBR). However, these centralized approaches tend to be bottlenecks regarding performance and fault tolerance. A proposed solution is the replication of registry information among multiple distributed Web service registries. In addition, the creation of specialized Web service registries leads to a large number of different Web service registries. This leads to a situation where the search for a particular Web service becomes a very complex task. Besides, Web service provisioning includes a considerable administrative overhead when dealing with transient Web services. Transient Web services exist only for a limited lifetime and in a certain context. In this paper, we propose the VISR (View based Integration of Web Service Registries) peer to peer architecture for the transparent integration of multiple Web service registries and transient Web service providers. This work focuses on the integration concept of multiple Web service registries an
