(808) document updates - two in rfc editor queue Yang Instance drraft is expired need to update it Balazs Lengyel - intend to work on the draft and sorry for the dealy Rob Wilton - liasions and communication work being done in 3gpp and O RAN - would be helpdfl for us make a liason providing advice for reuse Balazs - O RAN will use deviations from 3gpp models in specifications Lou - we need [consensus-derived] text (i.e., an RFC) to support whatever liason we write Balazs - The packaging document has such advice text. ## Chartered items: ### YANG Versioning Update (15 min) https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-module-versioning/ https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-semver/ https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-packages/ https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-ver-selection/ https://datatracker.ietf.org/doc/draft-ietf-netmod-yang-schema-comparison/ Jan Lindblad and Bo Wu First presentation in series Versioning Solution Overeview Jan Lindblad presenting Tom Hill - why are you adding white space now? should just be a minor release without a minor version bump, the model should be immuatable Jan - Makes good sense from that point of view Tom - takes months to upgrade thousands of routers, so knowing about incompatibilities between models is important Jan - Agree but determining what is and is not backwards campatible is subjective Kent - Yang doctors or someone not IANA should specify whether a module is backwards compatible Rob - Some models are derived from other registries. e.g. adding a new address family to BGP. IANA does need some consideration BO Wu - Presenting yang packages. Lou - Did you talk about alternatives e.g. update 8407 Bo- right now it's in the packages draft Rob - currently the document is focused on modules have we discussed holding virtual interims on the packages topic? Lou - are you suggesting that we hold one Rob - yes ## Non-Chartered items: ### Telemetry Data Self Explanation Tags (10 min) https://tools.ietf.org/html/draft-tao-netmod-yang-node-tags-06 Qin Wu Qin Wu - presenting data object tags ### A YANG Data model for ECA Policy Management (20 min) https://tools.ietf.org/html/draft-wwx-netmod-event-yang-10 Qin Wu 08:17 started Qin Intention is to raise adoption call Need to discuss with Andy whether his comments on the second draft are satisfied. The four issues listed here are already solved in this version Kent Watsen - The chairs can initiate the adoption call and we can see how it goes. This would typically be the last go around at adoption for this draft. Will follow up on the actions dicussed in this meeting. concluded 08:33
