Matchmaking and brokering are multiagent coordination mechanisms for Web services. Both have performance trade-offs, but the OWL ontology for semantic Web services (OWL-S) can handle extensions that address some of the shortcomings. In this article, the authors focus on the broker, which they analyze to explore its interaction protocol and the reasoning tasks it has to accomplish. The authors also describe OWL-S's exec extensions, detail their implementation's basic features, and explain how these features address the broker's reasoning problems.
