Abstract

   This document describes a YANG library that provides information
   about all the YANG modules used by a constrained network management
   server (e.g., a CoAP Management Interface (CoMI) server).  Simple
   caching mechanisms are provided to allow clients to minimize
   retrieval of this information.

1.  Introduction

   The YANG library specified in this document is available to clients
   of a given server to discover the YANG modules supported by this
   constrained network management server.  A CoMI server provides a link
   to this library in the /c/mod.uri resource.  The following YANG
   module information is provided to client applications to fully
   utilize the YANG data modeling language:

   o  module list: The list of YANG modules implemented by a server,
      each module is identified by its assigned YANG Schema Item
      iDentifier (SID) and revision.

   o  submodule list: The list of YANG submodules included by each
      module, each submodule is identified by its assigned SID and
      revision.

   o  feature list: The list of features supported by the server, each
      feature is identified by its assigned SID.

   o  deviation list: The list of YANG modules used for deviation
      statements associated with each YANG module, each module is
      identified by its assigned SID and revision.
