Business Process Management

Service Composition and Coordination
(KM-SC)



Service Choreography is a form of service composition in which the message-based interactions between multiple partner services -- called participants -- are defined from a global perspective. The goal is to define the message exchanges occurring between the participants (e.g. web services) from a global perspective. [PO-JRA-2.2.1], [Decker et al. 2008]

_ALT_

Service choreographies can be specified using graphical notations such as BPMN [BPMN, 2006] and Let’s Dance [Zaha et al. 2006], or using XML-based language such as WS-CDL [Kavantzas et al. 2005] and BPEL4Chor. [Decker & Kopp, 2007] {GEN: Service Composition}{SPC: Interaction Choreography Model, Interconnected Interface Choreography Model}

Service Infrastructure
(KM-SI)




Generic
(domain independent)



Service Choreography involves the collaborative processes involving multiple services where the interactions between these services are seen from a global perspective. [Barros, 2005]
