Abstract: Web services choreography description language (WS-CDL) describes collaborations of Web services participants from a global viewpoint. However, as a modeling language for business process, WS-CDL lacks the corresponding graphical notation standard such that it is difficult for choreographer to conveniently arrange business processes. Therefore, this paper designs a set of graphical model notation, WS-CDL-N,which has one-to-one relationship with WS-CDL. Furthermore, based on WS-CDL-N, a graphical editor is designed for WS-CDL via GMF. Finally, an example of E-commerce process choreography is utilized to show that WS-CDL-N has the features of higher abstraction level, intuitionist, and better interactions between participants.
