Re: [netmod] draft netmod charter update proposal

Hi Sue,

First, please be aware that the next version of revised-datastores
draft further defines the control-plane datastore concept.  This
includes providing guidelines that other WGs can follow to define
their own control-plane datastores, and includes an Appendix section
outlining the creation of an "ephemeral" datastore.  The idea is
to give the I2RS WG the ability to define datastore(s) as needed 
(read: future I2RS WG drafts).

Regarding:

> Does c) and d) include additions to include I2RS ephemeral state

> data stores?

I don't fully understand the question, but believe that the NETMOD
activities needed to support I2RS are all covered by a), b), and c).
Things that belong to NETCONF WG will include any needed changes to
protocol, YANG-Library, or any other draft maintained by that WG.
Everything else goes to I2RS.

I'm not sure what Mehmet means by a "joint session", but I think
that it's too late to add such a session to the IETF Agenda at 
this point.  That said, I plan a schedule another datastore 
breakout session (likely on Wed morning) that could be used to
discuss I2RS some, and I also plan on attending the I2RS meeting
Wed afternoon.

Sounds good as a first approximation. Though we need to discuss the details
and agree.
It might be useful to plan a joint session on Tue or Wed in Chicago.

Cheers,
Mehmet
