Hello NETMOD working group,

We are planning a one hour Virtual Interim meeting one day during the week of Dec 14-17 (9:30am Eastern Time).

The goal is to progress on some key outstanding decisions around the YANG Versioning drafts.

### YOUR RESPONSE REQUESTED ###
Please fill in the doodle poll with what days in the Dec 14-17 you could arrange your schedule to attend.
- If you will, or even *may* attend, then please fill in the doodle poll
- if you don't intend to attend, then please do not fill in the doodle poll
https://doodle.com/poll/4gycdqy8if2xc4yx

The focus of this Virtual Interim meeting will be the YANG Module Revision Handling draft:
https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-module-versioning/

The key issues that need discussion and resolution are:
A) Behavior of import by revision-or-derived and do we need revision-or-compatible-derived ? Is changing the import statement a BC or an NBC change to a module ?
B) Whitespace: do all whitespace changes require a bump in the revision? Consider interactions with package checksums.
C) IANA considerations: how are final RFC revision labels assigned ?
D) YANG file naming when revision labels are being used (symbolic links? @<revision-label>) ?

Meeting materials are being prepared and will be available for the discussions.

Some further details can be found at the following links for now:
