On T4 (gaps in revision numbers and revision history), I have some proposed text for both draft-ietf-netmod-yang-module-versioning and draft-ietf-netmod-yang-semver. See these diffs (some changes are due to xml2rfc changes, but you'll note the more substantive text additions). Thoughts:
module-versioning : https://tools.ietf.org/rfcdiff?url1=draft-ietf-netmod-yang-module-versioning&url2=https://namale.marcuscom.com/~jclarke/draft-ietf-netmod-yang-module-versioning.txt yang-semver : https://tools.ietf.org/rfcdiff?url1=draft-ietf-netmod-yang-semver&url2=https://namale.marcuscom.com/~jclarke/draft-ietf-netmod-yang-semver.txt Joe On 1/12/21 13:43, Sterne, Jason (Nokia - CA/Ottawa) wrote: YANG Versioning Weekly Call Minutes - 2021-01-12 Topics and owners for Feb virtual interim: Reshad - editor for YANG versioning draft Jason - coordinate virtual interim, agenda.

Other topics we need to get back to at some point: - whitespace - github issues (left off at #15) Jason
