Value Network Based Service Choreography Design and Evolution

The authors present a pattern-oriented service design and evolution approach by transforming the high-level service value network into service choreography scenario. In this approach, "Value" is considered the ultimate goal of a service, and designing an executable SOA-based service system starts from the acquisition of business-level value exchange relationships between participants in the service. Such value information is modeled as Service Value Network (SVN). Following a four-step process, SVN is gradually mapped to software-level service choreography and the corresponding interface design, thereby keeping the consistency between both levels.
