The SvcV-2 Service Resource Flow Description model describes Resource Flows exchanged between Services.

Service definition includes, among other things, the definition of interfaces, and connecting the interfaces to service definition components.

The main entry point of the SvcV-2 model is the Service Resource Flow Description folder. This concept matches the definition of the exchange protocol that must be fulfilled to benefit from the exposed services.

An exchange protocol (or Service Definition) defines how a consumer and a provider must behave in order to carry out a particular service. These exchange protocols are connected to the service points. The service that displays this service point will play the role of the provider in the exchange protocol (or Service Definition).
