Adding to what Alex said, here are a few questions left undefined in the latest draft which are worth exploring either on the NETCONF mailer or in Prague...

(1) Should this draft support the ability to suspend / resume a Subscription at the request of the Subscriber?

(2) Should the loss of authenticated access to YANG subtree be communicated to the Subscriber?

(3) Are there filters which should be provided beyond RFC 5277 Subtree and Property Filters?

Thoughts on these, or other suggestions/questions on the draft are appreciated.

Hi,

we just wanted to let you know that we posted a new version of the YANG datastore push draft yesterday, which we are planning to present in Prague.  

Please see https://www.ietf.org/internet-drafts/draft-clemm-netconf-yang-push-01.txt 

There are a a few technical updates, as well as quite a few editorial updates.  

The technical updates include:
- A parameter that allows a subscriber to specify which encoding to use for datastore updates
- A parameter that allows a subscriber to limit on-change subscriptions to certain types of changes

There are a few items that may warrant discussion, most of which can be found in section 3.10, including:
- Introduction of additional built-in datastreams limited to operational data (section 3.10.5), which we think would be a good idea to formally include in the next revision
- Whether to support subscription persistency (currently the subscription lifecycle is tied to the lifecycle of a Netconf session)
- Whether to provide guidance on "chunking" of updates (currently left to the implementation whether to send a single update message with the entire data, or multiple update messages each with a subset of the data)
- Whether to track the "owners" of a subscription as part of the subscription data model (again, we believe this is a good idea which we plan to add in the next revision) 

Regards

A new version of I-D, draft-clemm-netconf-yang-push-01.txt
has been successfully submitted by Alexander Clemm and posted to the IETF repository.

Name:		draft-clemm-netconf-yang-push
Revision:	01
Title:		Subscribing to YANG datastore push updates
Document date:	2015-07-06
Group:		Individual Submission
Pages:		32
URL:            https://www.ietf.org/internet-drafts/draft-clemm-netconf-yang-push-01.txt

Abstract:
   This document defines a subscription and push mechanism for YANG
   datastores.  This mechanism allows client applications to request
   updates from a YANG datastore, which are then pushed by the server to
   the client per a subscription policy, without requiring additional
   client requests.

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.
