           YANG subscribed notifications via SACM Statements

Abstract

   This document summarizes a subset of the emerging generic SACM Data
   Model for inter-component distribution of SACM Content in and between
   SACM Domains.  The subset defined in this document is covering every
   information element that can be acquired using YANG based protocols,
   i.e. NETCONF, RESTCONF, COMI or derived mechanisms that transfer YANG
   modeled data, such as MUD.  As subscriptions to data origins in a
   SACM domain are one of the architectural corner-stones of the SACM
   architecture, this document recommends the use of YANG Push, YANG
   subscribed Notifications and corresponding Notification Headers and
   Bundles.  Analogously, a mapping of Notification Header content to
   SACM Metadata is provided in this document.

1.  Introduction

   This document defines an XML encoding of SACM Statements that contain
   SACM Content composed of YANG modeled data (i.e.  NETCONF messages).
   Correspondingly, this documents provides a standardized mapping to
   derive SACM Metadata from YANG Subscribed Notifications
   [I-D.ietf-netconf-subscribed-notifications] using Notification
   Message Headers and Bundles [I-D.ietf-netconf-notification-messages]
   content.

   Every message defined in the generic SACM Data Model is a SACM
   Statement.  The SACM Statement structure is provided by the SACM
   Information Model.  In consequence, a SACM Statement is an
