                         draft-ietf-core-sid-14

Abstract

   YANG Schema Item iDentifiers (YANG SID) are globally unique 63-bit
   unsigned integers used to identify YANG items.  This document defines
   the semantics, the registration, and assignment processes of YANG
   SIDs.  To enable the implementation of these processes, this document
   also defines a file format used to persist and publish assigned YANG
   SIDs.
