Re: [Netmod-ver-dt] prelim IETF 107 slides for version selection

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

I've updated the version selection slides a fair bit. Enclosed and comments appreciated.

I added some details to the issues and reordered things to put the NETCONF issues first.

I added a slide to show relationships between packages, datastores and schema-sets.

I added a slide to defer questions about the other drafts.

Hi Joe,

I like your point about the filename issue, but that's something for yang-module-versioning (not these slides).

Ah, yeah.  Sorry.  I saw ‘@‘ and went to the filename thing since I had that on my mind.



Our version-selection slides do have an issue about numbering but it is about the schema-set name.

I added the bullet you mention to the last slide.

Thanks.

Joe

Since I had the issues part, a few perhaps aids there.

For the file naming issue, I think showing an example of:

ietf-interfaces@2018-02-20

vs.

ietf-interfaces@1.3.0<mailto:ietf-interfaces@1.3.0>

Is one way to illustrate the challenge.  But smart parsers will deal with this easily.  I think the bigger risk is something like this:

vendor-example@2020-03-29

vs.

vendor-example@2020-02-31

Where the latter is the second vendor release of 2020 with build ID 31 (something silly, but doable with revision-labels).  Parsers that blindly assume something that looks like a date is may have other issues.  Sure, we could add verbiage that a revision-label can’t look like a date or a semver, but perhaps it’s easier to have:

vendor-example#2020-02-31

===

On the last slide, based on our discussion the other day, should we add a bullet that says, “DT prefers this to remain as one document in netconf”?

Hi Jason,

Slides generally look good to me.

A few minor comments:

On slide 2:

•        Perhaps change “some on the client” to “minimal for the client”[>>JTS: ] changed

On slide 3:

•        I wasn’t sure that the second bullet completely scans.  Should it just be “It can also be used to allow clients to select between YANG schema defined by different organizations”?[>>JTS: ] Yes - changed

Between slides 4 and 5:

•        I think that it might be helpful to have an extra slide after 4, that covers the “selectable” leaf-list, and perhaps default too, both in configuration and <operational>
[>>JTS: ] Added new slide 5 - please take a look.

•        Having a diagram to show the relationship between packages, datastore-schema, schema-sets, might be helpful, but only if someone has the time to do them.
[>>JTS: ] I'll try to get some cycles to do that.  Basically that schema-sets are comprised of packages (or rather packages for each datastore).  But what do you mean by datastore-schema? That term is mentioned once in the version selection draft. Is it defined somewhere else?

Thanks,
Rob

Hi guys,

I put together some slides on the changes to version selection since the previous IETF in case someone needs to present these next week while I'm away (seems unlikely though).

Joe - can you take ownership of this preso for next week and add your "Issues"?

If we don't present before I'm back (Monday March 23) then I can help polish them further but I wanted to at least get this part to the DT.

Rgds,
Jason
