Abstract

The most promising feature of the Web services platform is its ability to form new services by combining the capabilities of already existing services, i.e., its composability. The existing services may themselves be composed of other services, leading to a hierarchical composition. In this work, we focus on the monitoring aspect for hierarchical Web services compositions. We are primarily interested in capturing the state of a hierarchical composition at any given point of time (snapshot). We discuss in detail how some of the snapshot algorithms proposed in literature can be extended in a Web services context. Snapshots usually reflect a state of the system which “might have occurred”. Towards this end, we show how we can acquire a state that “actually occurred” from such snapshots. Finally, we discuss the different types of execution related queries and how we can answer them using the captured snapshots.
