The service design view clusters elements of the Service Metamodel that are relevant to the Service Designer.

A service definition (shown on the left in the figure) comprises of a selection of a communication pattern and a selection of a communication object. A communication object is a data structure that is communicated between a service provider and a service requestor. The exact direction of communication is defined by the communication pattern (see also Communication Pattern View). The communicated data structure is independent of the underlying communication middleware that is linked in another development phase as explained in the preceding section above.
