With the development of Web services technology, cross-organizational and cross-enterprise collaboration is becoming more and more frequent and more complex, in order to more quickly and efficiently carry out development and integration of service across organizations and enterprises, the majority of researchers have begun to research and breakthrough technology of service choreography. In service choreography, there are mainly two ways of modeling, one is graphical modeling methods, such as BPMN, another is structured text modeling methods, such as WSCDL. While in the validation of the correctness of service choreography theory as well as whether it can meet the real needs of the service composition, the industry proposed service interaction patterns(SIPs) to evaluate the presentation capabilities of service choreography theory.Artifact-centric service choreography, which aimed at using the state transition of critical data in the business processes as the main line of the whole process of the design of service composition. Such a data-centric design approach, more in line with the manner of behavior in real life.This paper presents a Artifact-centric Web service choreography theory and defines the graphical and textualized model expression manner of Services choreography. They are Artifact-centric business process modeling notation and Artifact-centric web service choreography describe language.Then I verify an evaluate the theory by service interaction patterns.I also designed a graphical modeling tool ABPMNTOOL, and achieved process simulation,because it can help the business people designing a choreography model,modeling the working ofthe model and expressing the interactions relationship between business needs and servicesclearer and more intuitively.In actual use, service choreography theory and the modeling tool are mainly in the operational phase of service composition,while in the operational phase, developers depend more on business process execution language, especially BPEL.In order to realize that service composition could be shift from the design phase to the operational phase,this paper also gived a method for transforming a set of graphical models to BPEL language.Finally, through online travel instances, I examinedthe Modeling capabilities of Artifact-centric web service choreography theory and the usage situation of the tool. The results show that the theory could correctly design service composition language and transfer Execution Language BPEL.
