[14:08:40] Vanessa Issah joins the room
[14:09:39] <Ludwig Seitz> mic is not working
[14:09:46] <Ludwig Seitz> I can't hear the question
[14:09:59] Mawaba Liebe FAWIYA joins the room
[14:10:22] <kivinen> He was not using mic, because it was wired mic, and could not grab it close enough in the chair table.
[14:10:50] <Keith Moore> mic: IMO the architecture anticipated by ITU-T is a poor one as it does not adequately cover the variety of scenarios required by different IoT devices, based on differences in device function, connectivity, available power, etc.   IETF should not try too hard to align with it, other than to avoid conflicting/confusing terminology.
[14:11:12] <Brendan Moran> mic: there was a line in the ITU-T document says "the status tracker may reside inside a status tracker"
[14:11:18] Andrew Feren joins the room
[14:11:20] <Keith Moore> LOL
[14:12:53] <kivinen> jim reid on mic
[14:13:27] Vanessa Issah leaves the room
[14:13:29] <kivinen> someone on mic, no idea who as he does not have badge, and could not make anything from the name
[14:14:56] <Dave Thaler> that was Takeshi Takahashi
[14:15:04] Vanessa Issah joins the room
[14:15:15] <Dave Thaler> (author of the ITU-T doc and the SG17 liaison to us)
[14:17:22] Taiji Kimura joins the room
[14:24:05] <Brendan Moran> Mic: barring any further commentary, I think it's done.
[14:24:20] Robin Wilton joins the room
[14:24:30] <kivinen> https://datatracker.ietf.org/meeting/105/materials/slides-105-suit-suit-manifest-format-and-behavioral-manifest-00
[14:25:11] Vijay Satti joins the room
[14:26:07] Uffa Modey joins the room
[14:26:29] <Brendan Moran> How should we handle the poor audio?
[14:26:39] <Brendan Moran> I can try and fix it, but it will take about 5 minutes
[14:27:22] <Brendan Moran> ok
[14:27:51] <kivinen> Hannes will cover some of the slides, on slide 5 now.
[14:27:58] Rainer Schoenen joins the room
[14:29:07] Danny Alex Lachos Perez joins the room
[14:29:32] Brendan Moran leaves the room
[14:31:48] Brendan Moran joins the room
[14:32:37] Yannick Gaudin leaves the room
[14:32:57] Brendan Moran leaves the room
[14:33:58] Robin Wilton leaves the room: Replaced by new connection
[14:34:17] Robin Wilton joins the room
[14:34:21] <Uffa Modey> audio is quite poor. is it only at my end?
[14:34:33] Folli Herbert AMOUZOUGAN joins the room
[14:34:55] <Meetecho> Sounds fine here, in our monitors
[14:35:22] Yannick Gaudin joins the room
[14:35:23] Ching-Heng Ku leaves the room
[14:36:19] Brendan Moran joins the room
[14:36:45] <Meetecho> Uffa Modey: we see about 5000 lost audio packets on your end, may be a local issue; you can try closing the speaker video feed (hover on it and press X), to only keep slides+audio, to see if that helps
[14:37:12] Vijay Satti leaves the room
[14:38:00] Erik Nordmark joins the room
[14:38:10] <Brendan Moran> ive done that now, i will try aggain
[14:42:16] Hirochika Asai joins the room
[14:47:25] Robin Wilton leaves the room: Replaced by new connection
[14:47:44] Robin Wilton joins the room
[14:49:06] <Ludwig Seitz> can the person asking the question get closer to the mic?
[14:49:15] <Ludwig Seitz> He is barely audible
[14:49:32] <Ludwig Seitz> Much better, thanks
[14:50:18] <kivinen> he was pointing out that this draft is informational and post merge it should be standard track, and it was agreed to be changed when it is resubmitted...
[14:50:20] <kivinen> Hannes on the mic.
[14:50:44] <Keith Moore> mic: this all seems needlessly baroque to me.   update instructions in particular seem fairly likely to be platform specific.
[14:51:43] Brendan Moran leaves the room
[14:51:56] Brendan Moran joins the room
[14:52:30] <kivinen> dave on the mic
[14:56:51] Satoru Kanno joins the room
[15:02:42] Taiji Kimura leaves the room
[15:03:21] Mawaba Liebe FAWIYA leaves the room
[15:05:18] <kivinen> benjamin damm on the mic
[15:05:44] <kivinen> (he actually have badge, so I can get the name)
[15:05:58] <kivinen> Hannes on mic (without badge :-)
[15:08:13] <kivinen> benjamin again on the mic
[15:08:26] <Keith Moore> mic: One concern I have is: how many different things does an implementor have to know and understand in order to build an implementation that's appropriate to their product?   Some things like hashes and signatures are unavoidable.  But encoding really needs to be as simple as possible, the manifest model needs to be as simple as possible, encoding behavior strikes me as making things too complex for some use cases, etc.
[15:08:43] Peter Koch leaves the room
[15:09:26] <Keith Moore> we should keep in mind that the implementor audience for this is much wider than for a typical IETF protocol
[15:11:44] <Keith Moore> mic: could not hear all of what B was saying but I don't think the implementation is what needs to be demonstrated.   if the specifications aren't clear, an example implementation won't solve that.
[15:12:10] <Brendan Moran> mic: I think it will turn out to be much simpler than you expect. We also need to provide a few example cases for different classes of device.
[15:12:18] <Keith Moore> *do not* think the implementation is what needs to be demonstrated
[15:12:38] <Keith Moore> (not that I mind having implementations of course, but the specification needs to be exceptionally clear and easy to implement)
[15:13:01] <kivinen> I noticed  my mistake and fixed it myself...
[15:14:23] <kivinen> that was hannes, roman  now on mic
