An Extended WS-CDL Method for On-Demand Web Service Selection

Abstract

With the development of web service applications, how to realize on-demand services selection according to user's personal requirements is a hot research work in modern times. WS-CDL (Web Services Choreography Description Language) is a W3C candidate recommendation for the description of peer-to-peer collaborations for the participants in web services interaction. However, the goal of the service choreography is lacking and we can't understand the information exchange from the whole point. This paper extends WS-CDL from the aspect of goal that services to implement, and this can lay the foundation of on-demand service selection. Finally, the feasibility of the proposed method is validated through a case study.
