1.  Introduction

   This document introduces a YANG [RFC6020] [RFC7950] data model for
   configuration scheduling.  This model can be used together with other
   YANG data models to specify a schedule applied on a configuration
   data node, so that the configuration data can take effect according
   to the schedule.  Such a configuration schedule can be one-time or
   recurring, with its properties persistently saved in the datastores
   of the management system server.

   The mechanism described in this document is designed to complement
   the one described in [RFC7758], which defines a capability extension
   to NETCONF to allow time-triggered RPCs.  Such RPCs can be executed
   at a future time moment, but cannot be repeated and is not saved in
