[netmod] IETF 118 Hackathon for Revision Label in YANG tooling

2023-10-31 Thread Per Andersson (perander)
Hi!

I just registered the following project for the IETF 118 Hackathon.

You are very welccome to join! Any feedback, experiences, or suggestions is 
appreciated.


Revision Label in YANG tooling

Champions
Per Andersson peran...@cisco.com

Project Info
draft-ietf-netmod-yang-module-versioning defines the revision-label 
extension, this change also also updates the specified filename schema for YANG 
modules (currently module.yang or mod...@-mm-dd.yang) to also support 
module#revision-label.yang.
Currently there are ongoing discussions about this change, if it should 
be or not. One question raised was that it could require a big effort to update 
tooling to understand the assumed filenames for a YANG module.
During this hackathon we explore if changing the assumptions on 
filenames, and other revision label extensions, for YANG modules requires a big 
effort.

[netmod] draft-ietf-netmod-rfc8407bis: must + error-message for "config false"

2023-10-31 Thread mohamed . boucadair
Hi all,

In the context of https://datatracker.ietf.org/doc/draft-ietf-pce-pcep-yang/, 
Dhruv has received in the past a comment about the use of "must + 
error-message" for "config false" data nodes. He reported that comment at 
https://mailarchive.ietf.org/arch/msg/yang-doctors/gWnXnyNHPVv_nZB1PQjThAwP1JY/,
 but without any follow-up.

rfc7950#section-8.1 includes a provision for the use of "must" for state data, 
but silent about the use of error-message. Some guidance for authors may be 
useful here.

The following options are being considered:

(1) Remove both must and error-message for config false data nodes
(2) Remove error-message but keep the must
(3) keep both

I think that (3) is OK as this is a formal way to detect anomalies in state 
data, but I'm open to hear what the WG thinks.

Opinions whether we need to include a mention about this in 
draft-ietf-netmod-rfc8407bis are welcome.

Thank you.

Cheers,
Med
