Many different approaches have been proposed towards the goal of flexible distributed heterogeneous interoperation of software systems using service composition techniques. Recent approaches are described in terms of higher level models rather than be coded at low level.

Current practice, however, sees the service process specifications, written in BPEL or other languages, again as being largely hard-coded rather than exploiting the potential exibility offered. We propose an approach that is influenced by related fields of model-driven development, conceptual modeling of business processes and workflows, semantic process descriptions and service matching through constraint satisfaction. They can be utilized in a complementary way to support dynamic, instance-based selection and composition of Web services, during runtime and extends this to provide self-modifying adaptation when circumstances change.
