Rob: Thank you for publishing the Yang versioning work update. It is a good step forward.
Will this group consider issues related to BGP model linkage and BGP protocol changes? An example of this problem is: 1) Version 1 of BGP Flow Specification had multiple RFC revisions. Multiple revisions may be running in the network at one time. 2) Version 2 of BGP Flow Specification may also be running in a network with different RFC revisions. The monitoring device needs to be configured based on the version and sub-version, and the monitoring needs to be tailored accordingly. If you are not examining this problem, then please just let me know. If you think the problem is solved, please kindly educate me offline.

We meet every Tuesday, and I've just forwarded the calendar invite to External ([email protected]<mailto:[email protected]>) Report This Email<removed-link> HI NETMOD, During NETMOD at IETF 124, if was pointed out that we are happy to have extra folks help with the versioning work. We meet every Tuesday, and I've just forwarded the calendar invite to the WG. If you are interested, you are welcome to join us. I think that we will meet on Tuesday 16th Dec but then will take a few weeks off over the holiday period. In terms of current doc/work status: * The module version, filename, and Semver drafts are done from a WG perspective, and are now with the AD/IESG, so these don't require any extra help. * We are currently working on some updated IANA guidelines and YANG packages. I think that the packages draft is getting much closer to being finished. * There is a potential draft related to how YANG packages should be used in the IETF (that I have started but it is still in a very each stage at the moment), this work may get deferred further down the queue. * Per and Michal are actively working on the schema comparison document (backed by an implementation), and this seems to be progressing well. * But there is also the schema selection document, https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-ver-selection/<https://shared.outlook.inky.com/link?domain=datatracker.ietf.org&t=h.eJw9jkFugzAQRa8SeV1jbLCBSJVyFXdmCChgV-NJorTq3Ys32T69__R_1Z03dT6pReS7nI3BKFE4wo24WUnmJvPVYAaDHGfRFelEsmfUr5iu-kGsC20EsuZk1MdJ3WruUI6hbf0YJutMWSJTuST8WRrIu8EWbRhCgNnjV9dZi-M8DhRaoCE4ssYOwbvJT_3YuOC97VxNU03zc90kp8--hbVArr0L7pHh_beqWNU3-PsHmmhJJg.MEUCIADeWZdp2Kv4JFtjzcUzUeQbPGPxU5KDQdGHkFkJtDrIAiEAg_zVMKO1MQ4Zv0ubIwLoej7ww5t48ADw_Ougcc33V74>, that is needed as part of the solution but doesn't have anyone actively working on this at the moment. There seems to be less energy amongst vendors to implement this draft. I think that some of us will go back to this after YANG packages work has completed, probably with an effort to simplify the solution as much as possible. If anyone is particularly interested in helping on this draft then that might be particularly helpful. Kind regards, Rob
