    abstract =  {This document specifies a standard file format for YANG instance data, that is data that could be stored in a datastore and whose syntax and semantics is defined by YANG models. Instance data files can be used to provide information that is defined in design time. There is a need to document Server capabilities (which are often specified in design time). Defining server capabilities is foreseen as the most important use of YANG instance data files.},
