Kurzfassung englisch:
Service-oriented Architectures (SOA) and Web services have received a lot of attention from both industry
and academia. Services as the core entities of every SOA are changing regularly based on various
reasons. This poses a clear problem in distributed environments since service providers and consumers
are generally loosely coupled. Using the publish/subscribe style of communication service consumers
can be notified when such changes occur. In this chapter, we present an approach that leverages event
processing mechanisms for Web service runtime environments based on a rich event model and different
event visibilities. Our approach covers 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. We show how this event
notification support was integrated into our service runtime environment VRESCo and give some usage
examples in an application context.
