13:07:08 <McCool> kaz: this is an IG call, so should be clear about WG relationship
13:07:26 <McCool> ... also, we have some guests, who are WG but not IG members
13:08:06 <McCool> ml: my understanding is that use case does not impact IP
13:08:45 <McCool> kaz: we should be clear about that and need to formally invite them
13:09:04 <McCool> mm: I propose we invite the guests to participate with a resolution
13:09:22 <kaz> s/members/members. we can still invite them to this call as guests. MunHwan and Changkyu, please consider asking your AC rep to nominate you as IG participants as well

13:11:19 <McCool> topic: minutes
13:11:31 <McCool> ml: notes from 6 Dec 2022
13:11:53 <McCool> ... looked at and merged several PRs, and reviewed use case for agriculture
13:12:19 <McCool> ml: kaz, you mind fixing the names, other than that fine with publishing them?
13:12:43 <mlagally> https://www.w3.org/2022/12/06-wot-uc-minutes.html
13:12:50 <McCool> ... hearing no objections, notes can be published, with the name abbreviations expanded
13:13:07 <McCool> topic: New Use Cases
13:13:32 <McCool> subtopic: Smart Agriculture - Milking Use Case
13:13:42 <McCool> ml: this is PR #200
13:15:13 <McCool> ... Automatic milking system for dairy farm
13:15:32 <Ege> Ege has joined #wot-uc
13:15:32 <McCool> mm: we should look at what we discussed last time; tagging, security, etc.
13:15:45 <McCool> ml: has been some improvements addressing this feedback
13:16:44 <Ege> q+
13:16:56 <kaz> ack k
13:17:11 <kaz> agenda: https://www.w3.org/WoT/IG/wiki/IG_UseCase_WebConf#Dec_20th.2C_2022
13:17:14 <McCool> mm: see tagging has been improved, but security still needs work
13:17:26 <McCool> ... however ok with merging for now
13:17:55 <kaz> i|this is PR #200|-> https://github.com/w3c/wot-usecases/pull/200 PR 200 - Add new use cases for smart agriculture-Milking|
13:17:55 <Ege> ack e
13:18:08 <kaz> q+
13:18:24 <McCool> ege: did comment on the issue
13:18:48 <McCool> ... also some feedback about why there is not as much detail on security and protocols
13:19:19 <McCool> kaz: but in summary ok to merge, and proposers plan to make improvements later
13:19:20 <Ege> q+
13:19:27 <McCool> ml: ok, also agree to merge it
13:19:34 <Ege> ack k
13:20:15 <McCool> ml: should however remove extra empty sections and move affiliation to the end of the document.
13:20:39 <McCool> ... would be helpful to include contributors to end of the document
13:21:05 <McCool> ... would like to ask submitters to make these changes, offline
13:21:32 <McCool> mm: for the record I agree to merging it offline after those changes
13:21:57 <kaz> q?
13:22:00 <McCool> mhchoi: agree, I will do
13:22:13 <kaz> rrsagent, make log public

13:22:33 <kaz> q+
13:22:36 <kaz> ack e
13:22:57 <McCool> ... but comment on process, want to do two phases, but feel that is a bit unrealistic due to gap between uc and req extraction
13:23:10 <McCool> ... would be better to gather requirements when the uc is submitted
13:23:30 <McCool> ml: yes, will have to think about how to improve process in next charter
13:23:55 <McCool> ... but the original idea is that anyone can submit a uc, and may not be aware of all the existing specs
13:24:20 <McCool> kaz: let's talk about this some other time
13:24:58 <McCool> mm: agree, we have to get to the WG charter discussion today
13:25:04 <kaz> s/let's/we've already started that discussion separately, so let's/
13:25:15 <McCool> topic: Other Contributions
13:25:27 <McCool> ml: new requirements template, defer
13:25:42 <McCool> ml: PR 202, adding coverage gaps
13:26:13 <McCool> ... the coverage document lists the current use cases
13:26:37 <McCool> ... I recently imported it into excel, did some cleanup, sorting, grouping
13:27:07 <McCool> ... and this PR includes an MD file listing and grouping the gaps
13:27:54 <McCool> mm: agree with merge, and I think this will also be helpful for our discussion next week
13:27:58 <McCool> ml: merges
13:28:04 <McCool> ml: next is PR 203

13:32:36 <McCool> ege: is mention of profiles, this is the issue with having multiple requirements
13:32:39 <kaz> ack e
13:32:54 <McCool> ... should be made clear if this is for current or next profile document
13:33:11 <McCool> ml: we have been narrowing down 1.0 to fit in the current charter
13:33:26 <McCool> ... so 1.x is for things that we don't feel will fit in the current charter
13:34:05 <McCool> ege: ok, perhaps can explain at the top of the document, was a little confusing from the name of the document

13:37:12 <McCool> topic: Requirements Coverage and Gaps
13:37:31 <McCool> mm: think we need to look at both coverage gaps and deliverable proposals
13:38:04 <McCool> ml: ok, but first want to clean up what we have, in particular get rid of duplicates
13:38:07 <kaz> i|think we|-> https://github.com/w3c/wot-usecases/blob/main/USE-CASES/coverage-gaps.md coverage-gaps.md|
13:38:20 <McCool> mm: ok, makes sense
13:38:52 <kaz> i|think we|-> https://github.com/w3c/wot-usecases/blob/main/USE-CASES/coverage.csv coverage.csv|
13:40:27 <McCool> mm: for a start, the semicolon indicates a set of requirements, so for instance sensory modality is not part of geolocation, but a different topic under accessibility
13:40:35 <McCool> ... also alternative I/O
13:41:01 <kaz> q+
13:44:12 <McCool> mm: would keep FoI/SSN, geopose (orientation), topology
13:44:44 <kaz> ack k
13:45:16 <McCool> mm: to be clear about FoI, sometimes the location of that is different from the device itself
13:46:18 <kaz> q+
13:48:14 <McCool> mm: under protocol binding, not clear what LDWAN is about, that's not a protocol, but a communication technology
13:48:57 <McCool> kaz: suggest some categories, first there are "Other SDOs/Ecosystems/IoT Ecosystems"
13:49:16 <kaz> ack k
13:49:16 <McCool> ... then LPWAN, etc. are low-level protocols
13:50:38 <McCool> ml: ok, bit of overlap with KNX
13:51:08 <Ege> q+
13:51:10 <McCool> mm: also Matter is missing, would put under "Emerging standards"; and should be listed under smart home
13:52:09 <kaz> i/for a start/(all start to edit coverage-gaps.md dynamically based on the discussion during this meeting)/
13:52:20 <kaz> q?
13:52:31 <kaz> ack e
13:52:42 <kaz> q+
13:52:43 <McCool> mm: under security, I also thing we should add something similar for emerging standards, e.g. DID
13:52:54 <kaz> ack k
13:52:59 <McCool> ... also, I would add key distribution, esp on the LAN

13:53:49 <McCool> ml: complex interactions, thing graphs
13:53:49 <McCool> ... basically higher level descriptions
13:53:49 <Ege> q+
13:53:56 <McCool> ege: I think here we have two categories: groups of devices vs. complex interactions
13:54:15 <McCool> ... behaviour vs relationships
13:54:38 <McCool> ml: ok
13:54:52 <McCool> ml: Digital twins also mention twin graphs
13:55:06 <kaz> q?
13:55:11 <kaz> ack e
13:55:19 <kaz> q+
13:56:01 <Ege> q+
13:56:21 <McCool> kaz: not clear what graphs means here
13:56:26 <McCool> ... grouping, management
13:56:33 <Choi> Choi has joined #wot-uc
13:56:57 <McCool> ml: we have links already
13:57:06 <McCool> kaz: I think relationship is clearer
13:57:14 <Choi> Choi has left #wot-uc
13:57:46 <McCool> ... also, grouping and history were mentioned by ECHONET/Matsuda
13:58:13 <kaz> q?
13:58:18 <kaz> ack k
13:58:24 <kaz> ack e
13:59:00 <McCool> ege: for individual items that are in two categories, how can we relate, maybe duplicate, link somehow
13:59:05 <McCool> ml: what should I do?
13:59:15 <McCool> ege: eg. like 47 and line 55 are the same
13:59:45 <kaz> q?
13:59:47 <McCool> ... but they perhaps belong in two different categories
13:59:55 <McCool> ml: (adds a "see also" note)
14:00:09 <kaz> q+
14:00:34 <kaz> ack k
14:00:46 <McCool> kaz: please put a note about where we were
14:00:57 <McCool> ml: clear by formatting, but will add a note
14:01:12 <McCool> ml: AOB?
