13:17:21 <kaz> mm: we have two slots
13:17:25 <kaz> ... there are pros and cons
13:17:39 <Song> Sorry to correct, AB not BoD. :) kaz
13:17:53 <kaz> ... maybe we could move this one hour later, for example
13:18:11 <kaz> s/as BoD/as AB/
13:19:10 <kaz> -> https://doodle.com/meeting/participate/id/e7Yy1x1b 1st Doodle
13:20:16 <kaz> kaz: if we can move that call, we can consider that as an additional candidate
13:20:21 <kaz> mjk: ok by me
13:20:28 <kaz> q?
13:20:30 <kaz> q+
13:22:05 <kaz> kaz: we should ask the other people's opinions
13:23:28 <kaz> mjk: any problems, all?
13:23:39 <kaz> ... one single slot would be better

13:27:55 <kaz> mjk: Kaz proposes to create a GitHub repo
13:28:14 <kaz> ... should we have wiki also?
13:28:17 <kaz> q+
13:28:52 <kaz> kaz: would suggest we simply use GitHub only :)
13:29:07 <kaz> mm: easier to use only one MD notation :)
13:29:09 <kaz> q-
13:29:18 <kaz> mjk: ok
13:29:18 <Linda> +1 for github
13:29:23 <kaz> ... would make sense

13:32:09 <McCool> q+
13:32:47 <mjk> kaz: shares screen with the IG Charter and walks through
13:33:04 <mjk> ... we may need to add some liaison groups
13:33:29 <mjk> ... for example spatial data
13:34:13 <mjk> ... the biggest issue is we are 6 months late in the process
13:35:00 <mjk> ... the biggest question is how to create a web based platform for smart city digital twins
13:35:40 <kaz> [[
13:35:41 <kaz> Scope Summary
13:35:41 <kaz> Identification of stakeholders from the industries, countries/cities and communities to involve in the group's discussion
13:35:41 <kaz> Survey on the existing technologies and standards for Smart Cities, e.g., possible building blocks of Digital Twin Framework and standardized Vocabularies for Smart Cities
13:35:42 <kaz> Best Practices on what kind of technologies to be applied to what kind of Smart Cities applications, e.g., WoT, Automotive, Geospatial, VR/AR, Speech and Semantic Web to be applied to improved accessibility, visitor guidance and energy management

13:36:17 <mjk> s/hte/the
13:36:46 <mjk> mm: we should prioritize other W3C activities
13:37:07 <mjk> ... also think about gaps, what is gaps

13:37:43 <mjk> q?
13:38:02 <kaz> scribe+
13:38:04 <kaz> kaz: right
13:38:19 <kaz> ... let's discuss which group to start with first then
13:38:43 <kaz> -> https://www.w3.org/2024/06/smart-cities/#coordination Coordination
13:39:00 <kaz> mjk: Spatial Data
13:39:02 <kaz> mm: RDF-Start
13:39:06 <kaz> s/Start/Star/
13:39:51 <kaz> ... maybe we don't need to handle it ourselves in the end but we can look into their work
13:40:38 <kaz> ... note that different groups tackle different approaches
13:40:56 <kaz> ... need to understand how linked data is handled by them
13:41:04 <kaz> q?
13:41:07 <kaz> ack m
13:41:49 <kaz> kaz: maybe we can use the GitHub repo to continue our research for those topics
13:42:04 <kaz> mm: we can use GitHub Issues mechanism for that purpose
13:42:20 <kaz> mjk: ok
13:42:33 <kaz> ... we can start with creating GitHub Issues to initiate discussion
13:43:21 <kaz> kaz: once I've created a GitHub repo, you can create an Issue, McCool :)
13:43:32 <kaz> mm: and invite people to do so as well
13:44:12 <McCool> q+
13:44:29 <kaz> subtopic: Liaisons
13:44:43 <kaz> mm: organizations working on smart cities in general
13:44:57 <kaz> ... not necessarily an SDO
13:45:14 <kaz> ... intersection with the Web would narrow the scope later
13:45:27 <kaz> ... there are three bubbles here
13:45:33 <kaz> ... 1. Smart Cities
13:45:47 <kaz> ... 2. Web
13:45:56 <mjk> q?
13:46:04 <kaz> ... 3. Digital Twins
13:46:06 <kaz> ack m
13:46:08 <kaz> mjk: right
13:46:28 <kaz> ... given the success of ETSI around NGSI-LD
13:46:51 <kaz> ... some of the groups working on smart cities would make sense
13:47:20 <kaz> ... like a group of Matter
13:47:29 <kaz> q?
13:47:47 <kaz> subtopic: Existing resources
13:47:48 <kaz> q+
13:48:01 <kaz> mm: should have resources.md to gather information
13:48:13 <kaz> ... short summary of the topics
13:48:18 <kaz> mjk: yeah
13:48:55 <kaz> kaz: shall I do that?
13:49:01 <kaz> mm: good
13:49:19 <kaz> ... we should invite people to review it
13:49:38 <kaz> ... also we can talk about our priority as well
13:49:48 <kaz> mjk: like the NGSI-LD guys
13:49:51 <kaz> mm: right
13:50:03 <kaz> ... how to deal with geolocation information is important
13:50:14 <kaz> kaz: right
13:50:23 <kaz> ... we can ask Linda for help :)
13:50:41 <kaz> q-
13:50:53 <kaz> mjk: that would be a good place for the discussion
13:51:09 <kaz> q+
13:51:16 <kaz> subtopic: Deliverables?
13:51:32 <kaz> mm: can talk about our deliverables?
13:51:37 <kaz> mjk: good question
13:52:07 <kaz> [[
13:52:14 <kaz> Survey on the existing technologies and standards for Smart Cities (Technology Landscape)
13:52:15 <kaz> Best Practices on what technologies, e.g., WoT, Automotive, Geospatial, VR/AR, Speech and Semantic Web, to be applied for what kind of Smart Cities applications, e.g., improved accessibility, visitor guidance and energy management.
13:52:17 <kaz> Use cases and requirements for Smart Cities
13:52:19 <kaz> ]]
13:52:38 <kaz> mm: according to the Charter, the deliverables are as above
13:53:03 <kaz> lieven: meet a requirement or not
13:53:16 <kaz> ... meet a feature also
13:53:41 <kaz> ... what about prediction, cross-domain integration, etc.
13:53:45 <McCool> q+
13:54:31 <kaz> ... once formulate the requirements, should analyze possible gaps with potential standards
13:54:37 <kaz> mm: good point
13:54:47 <kaz> ... e.g., WoT is organizing user stories
13:55:08 <kaz> ... analyzing the purpose of the task
13:55:20 <kaz> lieven: would support that
13:55:23 <kaz> ack m
13:55:42 <kaz> scribenick: McCool
13:56:10 <McCool> suggest user story approach, As an X I need Y in order to Z.  Z is purpose, can also be a task (e.g. in order to make decisions based on data).
13:56:48 <McCool> X is stakeholder, Y is feature (e.g. property graphs)
13:57:22 <kaz> scribenick: kaz
13:57:40 <kaz> kaz: another topics is possible Team Report about Smart Cities
13:57:47 <kaz> ... I can generate some document based on the Charter
13:58:01 <kaz> ... and I believe it would be useful for our IG discussion as well
13:58:07 <kaz> topic: Next meeting
13:58:11 <kaz> mjk: next week
13:59:14 <kaz> ... will update the agenda on the GitHub repo
