Developing Coordination Strategies Using a Service-Oriented Model-Driven Approach

During the last decade, the service-oriented paradigm has been considered one of the most promising technologies for cross-organizational integration. One of the more challenging aspects for this purpose is the design and implementation of coordination between services, which appears to be complex using current low-level technologies. Service choreography stands out among the existing coordination alternatives. Its main features include the fact that every participant service has the same relevance, and therefore none of them is master over the rest. This article presents a proposal for the modeling of choreography-based coordination strategies. In particular, choreography development is achieved using a model-driven approach, which emphasizes the architectural aspect. The feasibility of the modeling proposal is checked by using a sport metaphor. We focus in particular on a real-world cooperation environment: a specific game situation in a basketball match.
