Revision label in filename

[Reshad-Rahman]

From Martin Bjorklund on draft-ietf-netmod-yang-module-versioning-00:

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

[Reshad-Rahman]

We agree that there is an impact on searching by date. We put this in to have the ability to search by revision-label, otherwise we can search just by date for a module which uses revision-label.
We had also discussed using different limiter for the label and have something along the lines of: module-or-submodule-name['@'date]['#'revision-label].yang
It'd seem that updating 7950 would be a good idea whichever way we go.

[Reshad-Rahman]

Latest discussions is to have 2 filenames with same content (may use symlink):
module-or-submodule-name['@'date].yang (unchanged)
module-or-submodule-name['#'revision-label].yang (new)

Last paragraph of 3.3 has to be updated too.

2 filenames (@ with date, # with revision-label) can be used as per section 3.3 of https://www.ietf.org/id/draft-ietf-netmod-yang-module-versioning-01.txt
