The "Interface node type" for this service
According to the Service Model Principles, any service definition will include a node type derived from onap.nodes.Service. This is a general ONAP service modeling convention rather than something specific for AR providing services. Just to remind - this type may be later use to create nodes of embedded services in a higher-order topology.
...
Providing service topology
Service Model Principles stipulate that any ONAP service definition includes, besides the "interface" node type, the implementing topology. The AR services are no exception of this principle.

The Consuming service definition, like any other ONAP service definition, will include an "interface node type". Its details are irrelevant for this example.
