Abstract

   This document defines a method to tag data objects associated with
   operation and management data in YANG Modules.  This YANG data object
   tagging method can be used to classify data objects from different
   YANG modules and identify characteristics data.  It also can provide
   input, instruction, indication to selection filter and filter queries
   of operational state on a server during a "pub/sub" service for YANG
   datastore updates.  When the state of all subscriptions of a
   particular Subscriber to be fetched is huge, the amount of data to be
   streamed out to the destination can be greatly reduced and only
   targeted to the characteristics data.  These data object tags may be
   registered as well as assigned during the module definition; assigned
   by implementations; or dynamically defined and set by users.
