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.
