Network Management Datastore Architecture (NMDA)
Abstract
Datastores are a fundamental concept binding the data models written
in the YANG data modeling language to network management protocols
such as the Network Configuration Protocol (NETCONF) and RESTCONF.
This document defines an architectural framework for datastores based
on the experience gained with the initial simpler model, addressing
requirements that were not well supported in the initial model. This
document updates RFC 7950.
