NetEdge This document describes a mechanism for mapping between YANG schemas and instance data and TM Forum (TMF) Data Models and APIs. The mapping mechanism enables orchestrators to produce and expose TMF compliant interfaces that provide TMF API consumers direct access to a YANG data store. Both a mechanism for the mapping of YANG schemas to TMF Catalog Specifications (i.e. TMF633/634) and a matching mechanism for the mapping of YANG instance data to TMF Order Management (i.e. TMF641/652) and Activation Management (i.e. TMF640/702) APIs are described.
