Abstract

Service-oriented Architecture (SOA) and Web services have become widely adopted for building cross-organizational and flexible applications. Yet, there is one issue inherent to this paradigm: services are changing regularly. Using the publish/subscribe style, subscribers can be notified when such changes occur. In current service registry standards, however, notifications are mainly used to inform about changes in the registry data, which does not include service runtime information. In this paper, we present an approach that leverages event processing mechanisms for Web services based on a rich event model that supports the full service lifecycle, including runtime information concerning service discovery and service invocation, as well as Quality of Service attributes. Furthermore, besides subscribing to events of interest, users can also search in historical event data.
