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

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.
