[second attempt, sorry for duplicates] Hi, By document: draft-verdt-netmod-yang-module-versioning-01 This is a great contribution to the YANG ecosystem. It is very well written, and I would like to see this document proceed quickly. The solutions it proposed are really needed. I have one objection though; in 7.1 the text says: All IETF YANG modules MUST include revision-label statements for all newly published YANG modules, and all newly published revisions of existing YANG modules. The revision-label MUST take the form of a YANG semantic version number [I-D.verdt-netmod-yang-semver]. I strongly disagree with this new rule. IETF modules use a linear history, so there are no reasons to use "modified semver". I support the adoption of this document. (I will send a review of this document in a separate mail) draft-verdt-netmod-yang-semver-01 This draft proposes a way to express how a given revision is backwards compatible in a very short format. With the new extension statements in draft-verdt-netmod-yang-module-versioning, this information is already present in the revision history of a module. (One possible exception is editorial changes, but that can easily be fixed by adding an "editorial" extension to "ietf-yang-revisions"). I don't think this document should be adopted. draft-rwilton-netmod-yang-packages-03 I support the adoption of this document. draft-wilton-netmod-yang-ver-selection-02 I think the solutions proposed in this draft are overly complex and some of them are probably impossible to implement correctly in real world use cases. I don't think this document should be adopted. draft-verdt-netmod-yang-schema-comparison-00 I support the adoption of this document. /martin Lou Berger <lberger@labn.net> wrote: > Hi, > We'd like to start a two week adoption call for the set of documents > described below by Rob.
