   Title:   A YANG Extension for Declaring the Comparability Scope of Operational State

Abstract:

   Several YANG modules currently in progress across multiple IETF
   working groups define counters, gauges, and other measured values
   that are exported from a network element and compared, summed, or
   averaged by a remote collector, either against the same node's
   history or against values from a different node. YANG (RFC 7950)
   has no first-class, machine-checkable way to state the domain
   within which two occurrences of such a value are comparable, so
   this determination is currently made, inconsistently or not at
   all, in prose. This document defines a YANG extension statement,
   "csc:comparability-scope", a four-value scope lattice, and a
   compatibility rule that lets a schema-aware tool statically detect
   an illegal aggregation across incomparable scopes, without waiting
   for it to happen at a collector.
