[netmod] NETMOD YANG Version Discussions - meeting minutes Oct 20, 2020

["Sterne, Jason (Nokia - CA/Ottawa)" <[e-mail]>]

Hi all,

In the call on Oct 20 we primarily discussed how deviations are captured in the Packages draft and compared it to YANG library.

We felt that deviations in packages should be primarily used by server implementations to report deviations, and that they should be avoided by standards bodies. If an SDO publishes a package that contains another standard package plus some deviations, then it makes it impossible for a server to ever support both of those packages together.  Jan Lindblad is putting together some proposed wording to capture this.

There was a fair bit of debate about whether to have some technically redundant information in packages about deviations (i.e. show the associations between modules and modules that contain deviations for the former modules). The feeling in the end was to avoid that redundant information. It could be out of sync and would mean there are 2 ways to discover/manage deviations. Tools can easily take a "single truth" and output various summaries, associations, etc if needed (i.e. show what module each deviation file is applying deviations to, or show which deviation files are applying deviations to a given module).  Note that Library has redundant information about deviations (the ro deviation* leaf-list is not technically necessary from what we can tell) but we aren't proposing to change that at this time.

We *do* need the nbc-changes leaf in packages though. Some NBC changes can't be discovered by tools.

For next meeting we need to discuss interactions between NBC indicators and deviations.

Rgds,
Jason
