Can other WG use this solution in the YANG modules they develop? Robert - the schema solution may be already supported by pyang while packages and versioning is not yet supported Robert - design team is officially complete authors will continue to meet regularly to work on these documents, those meetings will be open to all prioritize the delivery of versioning semver packages Lou - so long as the base set of drafts doesn't change the other two drafts completely but staging them --- Reshad presenting yang module versioning Kent - currently this is aimed at proposed standard it could be experiemental we will need to come to consesnsus on this Joe clarke - I think you're concerned about semver not module versioning. main issues from the adoption call Robert - one option is allow multiple versioning schemes, one problem with a single YANG statement is how to define the separate version schemes. Perhaps each version scheme defines its own extension label. Lou - reminder that we asked the question when the documents were split,that at some point we have to decide if need to allow for more than one [versioning format] Jason Stern - it is useful to have a prefered scheme you don't want to have to gues that the 1.2.3 pattern means something specific Reshad - further dicussion needed Martin - Discussion on whether revision 1.2.3 is somewhat dependent on whether YANG semver ends up being experimental rather than proposed standard. Lou - The decision as to whether a doc should be experimental or standards track can often be revisited at WG LC time. Tim Carey - It is much easier for tooling if they can easily understand what scheme is being used. Balazs - We should explicitly state the used schema for revision label. Reshad - presenting again slide 6/7 issues Balazs: status-description is good for the same reason a seperate reference, contact, organization statement is used. We could put all that into description too, but it would make it messier. --- Joe Clarke presenting yang semver Carsten Bormann - maybe not a good Idea to use lower and upper case m and use a different latter to differentiate Joe - worth dicussing on list to get a record given I don't think it has been dicussed before Sue Hares - I'm not sure we're going to get modules for some bgp features that won't have non-backward compatible features. Joe - if you need to a do a bgp2.0 semver would do that Lou - introduicing this may make non-backwards-changes more likely, and we already have examples of non-backwards-compatible changes in IETF Balazas - some other orgzations don't take backwards compatibility so seriously Italo - even if all the updates are linear and BC, there is still the possibility to have a 1.0.0 version in IESG process and a 1.1.0 version in WG process Joe - use use the lineage of the module and bc nbc tags, Charles Eckel - would make an nbc change but then bump the major version Jason Sterne - strong attempt to not use the m in ietf modules. at least this modified semver gives us a machanism to show that happen. Robert - semver allows the addition of descriptions after major revisions, this could be used for bis documents that haven't been republished as new RFCs Martin Mjorklund - module versioning draft makes this possible Joe - moving on to github issues #48 --- Bo wu - presenting versioned yang schema Jason Sterne design team has already taken an hour we should abreviate or push to the end the remaining two dt docs Lou - wouldlike feedback from the working group comments to the list. Jason - yang schema selection Kent - a similar dicussion will take place in the netconf meeting on monday Lou - chairs will talk on how best to coordinate between groups. --- Reshad - presenting yang schema comparison > > Not-Yet-Adopted items: > > TITLE: A YANG Data model for ECA Policy Management > PRESENTER: Authors > DRAFT(s) > https://tools.ietf.org/html/draft-wwx-netmod-event-yang-06 --- Qin Wu presenting a yang policy model for eca policy management.
