Abstract

Software systems are often built by composing together software services distributed over the Internet. Choreographies are a form of decentralized composition that models the external interaction of the participant services by specifying peer-to-peer message exchanges from a global perspective. Nowadays, very few approaches address the problem of actually realizing choreographies in an automatic way. Most current approaches are rather static and are poorly suited to the need of the Future Internet. In this chapter, we propose a method for the automatic synthesis of evolving choreographies. Coordination software entities are synthesized in order to proxify and control the participant services’ interaction. When interposed among the services, coordination entities enforce the collaboration specified by the choreography. The ability to evolve the coordination logic in a modular way enables choreography evolution in response to possible changes. We illustrate our method at work on a running example in the domain of Intelligent Transportation Systems (ITS).
