                     YANG Instance Data File Format
             draft-ietf-netmod-yang-instance-file-format-12

Abstract

   There is a need to document data defined in YANG models when a live
   server is unavailable.  Data is often needed at design or
   implementation time or needed when a live running server is
   unavailable.  This document specifies a standard file format for YANG
   instance data, which follows the syntax and semantics of existing
   YANG models, and annotates it with metadata.
