1.  Introduction

   This document provides an overview of a set of documents that define
   mechanisms that allow client applications to subscribe to and receive
   notifications and datastore updates.  Specifically, this includes the
   following documents:

   o  draft-ietf-netconf-subscribed-notifications
   o  draft-ietf-netconf-yang-push
   o  draft-ietf-netconf-netconf-event-notifications
   o  draft-ietf-netconf-restconf-notif
   o  draft-ietf-netconf-notification-messages

1.1.  Phasing of drafts

   This set of drivers has two themes:

   1.  an evolved subscription configuration data model and state
       transition messages, which, when paired with the existing
       [RFC5277] encoded one-way operation, provides a solution for yang
       push.
   2.  a new one-way notification operation that can provide robustness,
       flexibility, and extensibility.

   For theme 1, drafts [subscribed-notifications], [yang-push],
   [netconf-event-notifications], and [restconf-notif] provide solutions
   for an evolved subscription data model, pushing of YANG datastore
   changes as they happen, and periodic reporting of YANG datastore
   state.  Also enabled is the use of the evolved subscription model and
   subscription state transition messages on publisher based event
   streams.

   For theme 2, solutions are in the early stages for:

   o  automatic determination of which common headers to use, and
      selection of if/what transport bundling to use without requiring
      any change to YANG's 'notification' statement
