Hi, https://github.com/netmod-wg/yang-ver-dt/issues/45 o 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". It is ok to use rev:nbc-changes if needed, though. We believe some IETF models may not follow linear history, this was brought up (I think) for IDR. Modified semver allows for non-linear history and also doesn't preclude linear history. So even if we end up having no IETF modules using branching, modified semver still works. Regards, Reshad.

I think this needs to capture that no descendant statements to "input" can be reordered. Same for "output" (note, "input" and "output" in both "rpc" and "action"). o 3.3 All revision labels that match the pattern for the "version" typedef in the ietf-yang-semver YANG module MUST be interpreted as YANG semantic version numbers. I don't think this is a good idea. Seems like a layer violation. What if my project use another dialect of semver, that wouldn't be possible with this rule. I think this needs to be removed. o 3.3 Submodules MUST NOT use revision label schemes that could be confused with the including module's revision label scheme. Hmm, how do I ensure that this MUST NOT is handled correctly? What exactly does "could be confused with" mean? o 3.3 In the filename of a YANG module, where it takes the form: module- or-submodule-name ['@' revision-label] ( '.yang' / '.yin' ) Should this section update 5.2 of RFC 7950? I know that 5.2 just says "SHOULD". But existing tools implement this SHOULD, and they need to be updated to handle this new convention. But I wonder if this a good idea. It means that a tool that looks for a module with a certain revision date cannot simply check the filenames, but need to parse all available modules (wijust to find the o 3.4 leaf imperial-temperature { type int64; units "degrees Fahrenheit"; status deprecated { rev:status-description "Imperial measurements are being phased out in favor of their metric equivalents. Use metric-temperature instead."; } description "Temperature in degrees Fahrenheit."; } I don't think rev:status-description is necessary / worth it. This can easily be written with the normal description statement instead: leaf imperial-temperature { type int64; units "degrees Fahrenheit"; status deprecated; description "Imperial measurements are being phased out in favor of their metric equivalents. Use metric-temperature instead. Temperature in degrees Fahrenheit."; } o 3.5 The example modules should be legal YANG modules. Use e.g. "urn:example:module" as namespace. Also, the modules are missing the last "}", which confuses the "rfcstrip" tool. o 4.1.1 Alternatively, the first example could have used the revision label "1.0.0" instead, which selects the same set of revisions/versions. import example-module { rev:revision-or-derived 1.0.0; } Shouldn't this be s/1.0.0/2.0.0/g ? o 5 I think the module name "ietf-yl-revisions" should be changed to "ietf-yang-library-revisions". "yl" is not a well-known acronym. o 5.2.2 Wouldn't it be better if the leaf "deprecated-nodes-implemented" and "obsolete-nodes-absent" were of type "boolean" rather than type "empty"? o 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". It is ok to use rev:nbc-changes if needed, though. o 7.1.1 There is a missing " in: 4. For status "obsolete", it is RECOMMENDED to keep the "status- description" information, from when the node had status "deprecated, which is still relevant. HERE -----------^ o 8 s/CODE ENDS>/<CODE ENDS>/ o Both YANG modules All extensions should specify the grammar; i.e., in which statements they can be present and which substatements they can have. /martin _______________________________________________ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod _______________________________________________ netmod mailing list netmod@ietf.org https://www.ietf.org/mailman/listinfo/netmod
