Services involved in composition are accessed using the enterprise service bus capabilities (EasyESB or PEtALS DSB). It provides integration mechanisms and techniques for making heterogeneous services communicate and interoperate. It is based on a service discovery protocol for retrieving and querying services in the runtime context. In order to link design and runtime it would be interesting to connect the runtime naming service of the ESB with the governance registry. This way, we synchronize the runtime environment with the gouvernance framework.
