A

Chairs and the rest of the.

B

A

Girl- and I guess otherwise, our agenda for today is pretty light or.

C

Yes, so the the agenda is pretty light. um The the topics on on kind of document status are more like yeah, just think things are progressing there and the the respective authors are responding to the comments. So all is going well um and I'm not I don't so um we might, we might get a bit of, we might get a visitor from from c2pa, um but that's kind of very yeah.

C

If I manage to drop by level- and um I don't given that no one else has some anything currently pressing- we might stay with kind of. We might be a very small group today.

A

This is scott scott is here and ricardo hi. Oh hello,.

A

I don't know if you want to.

C

A

A little bit longer yeah.

C

I'd wait: I'd wait until like three to five minutes after after the hour, because we're only we are only the five of us so far.

A

C

C

So until until until the point where and I think that no one more will join us, you might want to have a look at the um at the um heck md. You know cody md, hedge dock um etherpad, whatever um that I just sent around in the chat.

C

So if there's anything you want to add to the list of things to talk to about today, it's not much really on it. Right now um feel free to add that right away or jump in when we go through the list.

C

ah Hello, peter.

C

Okay um being five uh four minutes past the era, I'd like to start this meeting hello and welcome everyone. This is an interim meeting of the sibo working group. You all know the procedures not well applies.

C

We have a few items on the agenda for today and it's really more of a brief status update, um um so I'd just say a few words on cdl control and the network addresses status and then point due to a work that has started around using zebra and cozy for image metadata.

C

Is there anything anyone would like to add to the list right now.

C

Okay, hearing nothing there, um let's go through the working group documents. Cdl control has received a few good comments from francesca teresa and general carsten has started working on them and their biggest issue that I've seen. There is the question that we've discussed earlier already, but might we might need to revisit?

C

That is whether this document should really be um informational or whether it needs to be on the standard track, um depending on how the um how the properties of extending an eye on a registry of utilizing of adding a point to the iana registry um are interpreted, it might be. That kind of this is not necessarily something that only the working group needs to concern itself with, but this is a more general question that probably concerns a wider range of of ipf.

C

On the network addresses there have been comments as well, um as I understand michael is about, uh is, is on it, so this can this can progress, as it has been already um nothing really new. If you hold questions raised again.

A

So um for the city we have control, I don't have anything against moving into slander track, as I was telling the authors. um If, if the working group agrees, there is consensus that this is makes more sense, uh this will need another two weeks last call so I will have to restart the last call. So um I think there's so there is a bit of issue I've seen discussing this right. So maybe it's good.

A

If uh the chairs or custom can uh you know, get some some more opinions if needed or just call consensus uh so that I can either start this second last call or move the document forward.

C

Okay, so you see this um more as a working group um question and and not just a procedural itf general question.

A

It's uh yeah, I I agree that I mean standards track, makes sense from also from what, uh like uh the comments weren't during that last call but uh yeah it's it's up to you chairs. If you feel like that, that's enough uh input or if you want to have a more official call or you know, or even discuss it during this meeting, just see. If anybody has opinions or objections about this.

C

So from from my second phase, shepard point of view, the consensus around this document would have been strong enough just as well for generous track document um just to confirm or get get a wider perspective, um marco peter rickard scott. Do you have do you have what's your feeling about this document? Is there anything that you what what where why you would rather have this not as a consensus of the working group or just a thing that we that we make statements about, but don't don't endorse, particularly.

C

That was a massive sentence.

A

Information like it's still a consensus document.

B

Yeah, marco here there's an argument that keeps recurring and and karsten mentioned it about this document again and was used also recently for cinema data ct. um Even if the information might be enough, uh standard track is still appropriate. That ensures more visibility so say especially for other organizations that can use the document and would be a bit intimidated. Maybe to read all new information out there.

B

So I think thunderstruck would be fine.

C

Thank you. That's that's! That's! That's! Actually, a good point um now that you mentioned it. I remember having a very similar, um similar input received on the on the. What was it um core? No response option uh with also even of itf documents being doubtful about using it just because it was an informational document, so that adds another that adds another point towards the he has done this track. It should probably be listed.

A

And cdl like okay, so this was informational because it does uh like defines extensions to a registry that is specification required, so it doesn't need to be standard track, but you know cdl is under track. So to keep that consistency to me, it makes sense to have this center track as well.

C

Yep, um we'll um very maybe we can have a briefchat at the end of this, but I think just from from now we can probably even proceed here um without any any further delays.

A

Yeah, so just let me know cc mean whatever yes and then I can in case restart this that's cool and then for the s for the other document. That is with me, which is the network addresses which has ended last call, and I think the there was nothing majors made no major comments in the review, so I think I will just uh add it to the next telechat agenda and hopefully, michael can post an update soon.

A

The next telechat is in two weeks, so that should be enough time.

C

C

um Now, on to the point about seaboard use and other sdos, which we've been discussing uh on and off whenever it came up, came around, I've recently received a mail from philip vendeville. I hope I'm pronouncing your name right here about c2pa efforts to use sieber and cozy in image metadata philip as you're around. Could you maybe say a few words about what you're, what you're planning to use this for or how this would interact with your larger ecosystem.

C

I'm seeing you as having audio on occasionally, but not I don't hear anything.

C

A

Did you allow you have to give like this permission to the browser.

C

On your track closed, I haven't seen that one yet um just to to rule out. uh Can you try, even though it should work, can you try the join the cue button, it's on the on the left, most icon, and then I would clear you for audio manually.

C

ah Damn it sorry that was my wrong button again. Please.

C

Okay, um apologies that changed so can you try unmuting now.

C

Okay, um well, then, I'll just I'll give give a brief summary of what I've seen from this document. So far and from from the from the chat- and you just um tell me tell me if I'm saying anything stupid on the chat, uh so c2pa is looking into uh using seaboard data for signing uh for signing assertions about uh pictures that are usually in saying in defect form and possibly have um exit metadata or xmpp metadata and scientific. It and sibo would be a relatively compact, a way of signing that data and.

C

Making sure all the cryptographic components are where they should be.

C

This is the the first public draft has just been uploaded a few weeks ago, so um I'm I'll probably have a longer read about just to read that through and if anyone else is interested in conflicting what what seaboard is used for there. I invite you to do the same um phillip uh towards you. um If any questions come up as to as to how best you cdl and cbor- and I see that this even even cdl is used.

C

A lot in in that text um feel free to write the mailing list and let us know how things kill and.

C

C

With that, I think we are through the the part of planned documents and planned the gender points anything anyone would like to add or ask possibly also ask philip.

C

Oh yeah, um just for those not tracking the chat, um anyone working with or recommending good, c or c plus cosy libraries, um please get into contact with phil with philip, because that would be helpful.

C

Okay with that, I think we can call it a very short meeting thanks everyone for being here and bringing your topics here or documents in most cases and minutes will be uploaded thanks. Marco for taking notes, see you all in two weeks. Thank you.

B

Thank you bye-bye. Thank you all bye-bye. Thank you.
