Designing Service Choreography and Portal from Value Network

Designing a service system requires the model-driven transformation from business-level service models into IT-level software systems. Service Value Network (SVN) that describes the value exchange relationships between multiple participants, is considered as a useful tool to facilitate the service innovation and guide the designing of software service systems. In this paper, we present a general approach to design the service choreography (representing the interactions between multiple software services) and the portal (representing the entry of participants to access the service), based on the value network.
