There is a need to document data defined in YANG models without the need to fetch it from a live YANG server. Data is often needed already in design time or needed by groups that do not have a live running YANG server available. This document specifies a standard file format for YANG Based Instance data, that is data that could be stored in a datastore and whose syntax and semantics is defined by YANG models. Most important use cases foreseen include documenting server capabilities, factory-default settings, or vendor provided default configurations.
