An Event-based Model for the Management of Choreographed Services

We propose a mediation framework supporting a flexible management of choreographed services. The framework separates the management of the business logic of a service from the message flow details reported in the choreography specification. This abstraction step is achieved by introducing an event-driven management of Web Services and by exploiting a rich coordination context which includes business data and synchronization information. By separating activity management issues from communication details, our framework facilitates the management of interaction protocol mismatches between Web Services.
