Network Working Group A. Bierman Internet-Draft YumaWorks Obsoletes: 7895 (if approved) M. Bjorklund Intended status: Standards Track Tail-f Systems Expires: April 20, 2019 J. Schoenwaelder Jacobs University K. Watsen Juniper Networks R. Wilton Cisco Systems October 17, 2018 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. Status of This Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.
