UsiWSC: Framework for Supporting an Interactive Web Service Composition

Abstract

In this paper, we propose the UsiWSC framework for designing, deploying and executing Web service compositions with user interactions. The UsiWSC design relies on an extension of the BPEL standard: UI-BPEL. The extension supports the derivation of user interfaces as well as executable compositions for different user contexts. The UsiWSC execution requires the coordination of the control and data flows between web services and user interfaces.
