11:09:26 <McCool> mm: note I have not updated the profile IR, mostly have been working on arch IR
11:09:50 <McCool> ml: regarding events, ben was working on a PR
11:10:07 <McCool> ml: any objections to publishing?
11:10:19 <McCool> ... hearing none, we will publish these minutes
11:11:18 <mlagally> https://www.w3.org/WoT/IG/wiki/WG_WoT_Architecture_WebConf
11:11:35 <McCool> topic:new issues
11:11:45 <McCool> ml: new issue #190
11:12:31 <McCool> ... ben noted that use cases and requirements should be moved to another document; has "blocks publication", not sure why
11:12:38 <kaz> i|190|subtopic: Issue 190|

11:13:36 <kaz> -> https://github.com/w3c/wot-profile/labels/blocks%20publication Issues which block further publications

11:16:43 <kaz> present+ Sebastian_Kaebisch
11:17:02 <McCool> mm: suggestion to resolve this particular issue is to change name to "summary of use cases and requirements"
11:17:21 <McCool> ml: more general issue is we do need to review "blocks publication" usage
11:17:43 <McCool> mm: still only about 1/3 of the use cases are marked this way
11:18:18 <kaz> present+ Ryuichi_Matsukura
11:19:44 <McCool> topic: profile names
11:20:04 <McCool> ml: four have been proposed
11:20:22 <kaz> [[
11:20:23 <kaz> Core Profile
11:20:23 <kaz> Core HTTP Profile
11:20:23 <kaz> Baseline Profile
11:20:23 <kaz> Baseline HTTP Profile
11:20:24 <kaz> ]]
11:20:50 <kaz> q+
11:21:51 <McCool> mm: I would prefer "HTTP Baseline Profile"; core is contentious, and HTTP should be mentioned
11:22:16 <kaz> -> https://github.com/w3c/wot-profile/issues/5 "Core" profile name has undesired implications
11:22:54 <McCool> ml: I would support HTTP Baseline or Baseline HTTP
11:23:04 <McCool> kaz: so there could be extensions, right?
11:23:16 <McCool> ml: yes, for example, to include event
11:23:23 <McCool> kaz: in that case, concur
11:23:29 <kaz> ack k
11:25:13 <mlagally> proposal: use the name "HTTP Baseline Profile" for the HTTP profile that includes properties and actions.
11:26:40 <mlagally> proposal: use the name "HTTP Baseline Profile" for the HTTP profile that includes properties and actions. (closes https://github.com/w3c/wot-profile/issues/5)
11:26:53 <mlagally> resolution: use the name "HTTP Baseline Profile" for the HTTP profile that includes properties and actions. (closes https://github.com/w3c/wot-profile/issues/5)
11:27:44 <mlagally> Proposal: Split core into baseline + (multiple) event bindings
11:27:44 <McCool> topic: profiles for event bindings
11:28:47 <McCool> ml: see PR 118, draft where SSE and WebHooks broken into separate sections, and use names "HTTP Baseline Profile" plus "HTTP SSE Profile" and "HTTP WEbhooks Profile"
11:29:32 <McCool> ml: not sure how security go moved
11:31:09 <McCool> mm: looks like it was part of error responses, which was moved above events, which is fine

11:32:06 <RRSAgent> I have made the request to generate https://www.w3.org/2022/03/30-wot-profile-minutes.html kaz
11:32:40 <McCool> mm: my personal opinion is that having separate profiles for SSE and Webhooks makes sense
11:32:56 <McCool> ... although might lead to some fragmentation, better than alternatives
11:33:01 <McCool> ml: concur, let's merge

11:37:12 <McCool> mm: only one minor point, should really say "chronological order as seen by the server", but ok with merging as-is

11:40:17 <McCool> mm: I would like to suggest that we hold this PR and take comments and improve it.
11:40:27 <McCool> ml: have been waiting for comments
11:41:37 <McCool> mm: are there any constraints that are not data model constraints?  Eg. time and date formats are data model constraints.
11:42:06 <McCool> ml: would suggest merging as a placeholder for now; if we don't need it, can delete it later
11:42:33 <McCool> ... have a merge conflict, will fix
11:42:50 <McCool> mm: suggest extend ed note to say will remove if there aren't any
11:43:07 <McCool> ml: PR 127
11:43:24 <McCool> ... timestamps to action protocol binding
11:44:38 <McCool> mm: my concern is that not all constrained devices will have a clock
11:45:44 <McCool> ... and if this is mandatory, means that it can't be implemented on Things without them
11:46:14 <McCool> ml: let's start by assuming clocks are not synched, and might be low-resolution

11:47:52 <McCool> mm: not a total blocker, since devices capable of HTTP probably also have an RTC
11:48:13 <kaz> q+
11:48:31 <McCool> mm: but at the very least it adds a hardware requirements
11:49:25 <McCool> mm: feel there are two options: add hardware requirement, make it optional
11:49:31 <kaz> -> https://www.w3.org/TR/hr-time/ High Resolution Time
11:49:36 <McCool> kaz: wondering about resolution of time-stamp data
11:49:44 <McCool> q+
11:50:01 <kaz> ack k
11:50:09 <McCool> kaz: might want to see what it says about time resolution
11:50:26 <McCool> ml: would say it is very device dependent, resolution might be quite low
11:50:58 <McCool> kaz: depends on the use cases, we should perhaps define
11:52:35 <McCool> mm: agree, we should think about purposes: sequence, elapsed time for actions, etc.
11:52:53 <McCool> ... for instance, maybe we only need sequence numbers and relative time
11:53:30 <McCool> ... also, there is the problem of initializing the clock; when is that done?  Onboarding?
11:53:31 <kaz> q?
11:55:13 <McCool> ml: so sequence numbers and relative time?
11:55:28 <McCool> mm: may not even need that, have sequence from query ordering
11:55:46 <McCool> ... as kaz said, we need to be more precise about use cases
