WS-CDL+: An Extended WS-CDL Execution Engine for Web Service Collaboration

Abstract

Web services are becoming the prominent paradigm for distributing, computing, and electronic business, while there is an increasing surge to provide online business- to-business collaborations. The Web services choreography description language (WS-CDL) is a Web service specification developed by W3C, in order to provide peer-to-peer collaborations for participants from different parties. Despite the great research interests it has received during recent years, no practical or even prototype execution engine has been built for WS-CDL, which is, however, essential to test and evaluate the properties of WS-CDL when doing research on it, and promote its application fields in business. This paper implements an execution engine of WS-CDL, which has never been built before, and experiments on the functionalities and performance of the engine. We also address the extensions toward WS-CDL, namely WS- CDL+, which are built into our execution engine. Finally, the whole paper is concluded, addressing the application perspectives of WS-CDL/WS-CDL+.
