Service-Oriented Composition in BPEL4WS

Abstract

The advent of Web services is enabling a move towards service‐ oriented computing. In order for this new computing paradigm to scale, choreography standards that enable one to aggregate or compose existing services into new services are critical. Such standards would allow third‐parties to provide value‐added services very much like in real‐world service‐oriented economies. In this paper, we examine the compositional aspects of the BPEL4WS choreography language.
