Hi, All:
v-02 is posted, the main changes include:
o  Clarify the relation between data object, object tag, property tag
      and metric tag in figure 1 and figure 2 and related description;
   the key different with the v-01 is the object tag is only used to tag the top level data node that contain other data nodes.
o  Change Metric Group into Metric Type in the YANG model;
o  Add 5 metric types in section 7.2;
As we discussed in the last meeting, metric tag is more useful than object tag and property tag, we may only tag data nodes related to metric,
But object tag and property tag are optional tags and have these tags seems no harm.

Regarding metric type such as counter, gauge, we consolidate them with metric group such as delay, loss group and label them with metric type.
Another choice is to introduce the second level tag such as metric type tag, but we allow one metric related data object can be tagged with both delay metric group and counter metric type.
Distinguishing them in two different levels seems not necessary.

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.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
