Abstract

This paper puts forward a solution based on forward error recovery, oriented towards providing dependability of composed Web services. The proposed solution has no impact on the autonomy of the individual Web services, while exploiting their possible support for dependability (e.g., transactional support at the level of each service). Our solution lies in system structuring in terms of co-operative atomic actions that have a well-defined behaviour, both in the absence and in the presence of service failures. More specifically, we define the notion ofWeb Service Composition Action (WSCA) based on the Coordinated Atomic Action concept, which allows structuring composite Web services in terms of dependable actions. We then introduce a framework enabling the development of compositeWeb services based onWSCAs, consisting of an XML-based language for the specification of WSCAs and a platform supporting the execution of WSCAs.
