Liaison statement
Re: Liaison to IETF regarding draft NETCONF YANG models

The IETF appreciates the BBF reaching out regarding the status of the
referenced drafts. The BBF is surely aware that these important drafts
have been in development for a some time and are finally nearly done.

Before answering your specific questions, please be aware that the
drafts have all exited the NETCONF WG and are currently in the AD review
phase, IETF LC, or in IESG Telechat, moving in that order. Once the last
stage completes, the drafts will then move to RFC-Editor review phase
and publication.

Regarding the timeline for publication, this is difficult to predict
with accuracy. It is author’s and AD’s intention to have them to the
IESG by March. How long the IESG reviews take is unknown, but given
these drafts have been through two Security reviews, their long
development effort, and several implementations, it is anticipated that
few issues will be found by the IESG. Still, this phase may take several
weeks to complete. Upon being received by the RFC Editor, the drafts
should be published a few weeks later. All said, a realistic estimate
for publication is late Q2 2024.

Regarding the stability of YANG modules, they are currently undergoing
minor updates to, e.g., improve node names and validation expressions,
found by the AD and other reviewers. Only after the drafts have exited
the IESG review phase can the YANG modules be considered "technically
stable” with only editorial changes expected from the RFC Editor review
phase. Please keep in mind that Internet-Drafts are work in progress and
should not be cited or quoted in any formal document. See the IETF page
on Internet-Drafts <https://www.ietf.org/how/ids/> for details.

Thank you for BBF's interest in the IETF YANG development work. As
always, BBF participants are welcome to join IETF YANG development
efforts by participating in the IETF process.


Best,
Per Andersson
NETCONF WG co-chair
