Extending Web services with event-driven semantics
Matjaž Branko Jurič · 2011
SOAP Web services have so far supported operation invocation semantics only. This paper proposes extensions for web services to support event-driven semantics. Our solution enables services to act as event producers and event consumers. We have identified and designed the required extensions to WSDL. We propose a flexible XML representation of the event payload data. We introduce event sinks, sources, and triggers.
