                              YANG Library
                    draft-ietf-netconf-rfc7895bis-07

Abstract

   This document describes a YANG library that provides information
   about the YANG modules, datastores, and datastore schemas used by a
   network management server.  Simple caching mechanisms are provided to
   allow clients to minimize retrieval of this information.  This
   version of the YANG library supports the Network Management Datastore
   Architecture by listing all datastores supported by a network
   management server and the schema that is used by each of these
   datastores.

   This document obsoletes RFC 7895.
