Proprietary capabilities can also be added using the spec approach. ONF Spec Approach Pruned Core model is refactored to project familiar named items, for example: • Forwarding. Construct in the Core becomes both Connection and Connectivity. Service in TAPI. • Logical. Termination. Point in the Core becomes Node. Edge. Point, Connection. Endpoint and Service. End. Point in TAPI ONF Wireless Transport team have used the same approach to construct their interface model. Their model is different from TAPI IM Tooled Generation UML-YANG tooling generates conformant YANG from any appropriately structured model. Technology and service specific properties decorate structural classes derived from the ONF Core IM to form a fully detailed interface definition.
