1.  Introduction

   YANG [RFC6020] [RFC7950] became the standard data modeling language
   of choice.  Not only is it used by the IETF for specifying models,
   but also in many Standard Development Organizations (SDOs),
   consortia, and open-source projects: the IEEE, the Broadband Forum
   (BFF), DMTF, MEF, ITU, OpenDaylight, Open ROADM, Openconfig, sysrepo,
   and more.

   With the rise of data model-driven management and the success of YANG
   as a key piece comes a challenge: the entire industry develops YANG
   models.  In order for operators to automate coherent services, the
   industry must ensure the following:

   1.  Data models must work together

   2.  There exists a toolchain to help one search and understand models
