… regarding smart city topic, expecting this IG as a bridge for the existing SDOs and standards around smart cities

(Koster joins and we do quick intro again)

Koster: science and engineering background
… IoT and Digital Twins
… created digital twin-based building automation systems

Kaz: Michael is the Chair of this IG
… also co-Chair of the WoT-WG/IG

Daihei: would like to work on new areas for publishing, and interested in smart cities and digital twins

Hiroki: Hiroki Endo from NHK

… working for WoT around Architecture and Discovery
… would like to see the gaps between the existing standards and the current situation around smart cities

Logistics

Meeting schedule

Kaz: there was a proposal to move the Monday slot one hour later
… to accommodate Pacific/Asia guys also
… but would that be feasible?

Daihei: the question is if we could make some slot for each area
… slot 1 is 5 or 6 am in California on Monday
… if the other participants are OK, I can join that slot

Hiroki: technically, both would be OK
… but morning would be better, though

Kunihiko: also OK with the both slots

Kaz: thank you all!
… sorry about the inconvenience but would be great if we could have one specific slot
… Koster, would it be OK by you too?

Koster: yeah, fine by me
… we can proceed with the direction then

RESOLUTION: Slot 2 participants are OK to have one single slot on Monday at 11pm JST

GitHub

Koster: we'd like to use GitHub repo to manage agenda and resources
… would be better to have one place for that purpose
… anyone has any issue about that?

(no problems)

Kaz: ok
… I'll create a repo

Koster: any other considerations around logistics?

(none)

Charter

IG Web-based Digital Twins for Smart Cities Interest Group Charter

Kaz: (reviewing the charter document)

Kaz: the charter started early in the year but we started the discussion at TPAC

[ Koster is the chair and Kaz is the team contact ]

Kaz: The work is to identify stakeholders across industry, survey technologies, and determine best practices

<kaz> Scope Summary:

<kaz> Identification of stakeholders from the industries, countries/cities and communities to involve in the group's discussion

<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

<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

<kaz> Use cases and requirements for Smart Cities

Kaz: The deliverables are structured around these areas

<kaz> Deliverables:

<kaz> Survey on the existing technologies and standards for Smart Cities (Technology Landscape)

<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.

<kaz> Use cases and requirements for Smart Cities

Kaz: (reviews the list of related groups and liaisons)

Kaz: what are you opinions about other deliverables?

Hiroki: We should add the Media Contents Japan CG

Kaz: we can add more deliverables later

Next steps

Koster: what are the next steps?

Kaz: let's update the lists of the stakeholders on GitHub
… also start to invite key stakeholders to our calls

Koster: sounds good
… in addition to the official IG deliverables, we're expected to generate a Team Report around smart cities

Kaz: right
… I'd like to generate some short whitepaper about smart cities based on the Charter

Koster: ok
… then last night, McCool proposed we collect resources on GitHub

Kaz: right
… I can generate some template MD for that purpose

Koster: the "resources" should include the list of stakeholders
… survey on the existing standards, etc.
… then plan and prioritize our "deliverables"
… what else at the moment?

Kaz: yeah, let's start with those initial points

Koster: ok. we can find what our gaps are later
… regarding our liaisons, we should clarify the scope of each liaison
… for example, geolocation data is very important
… good area to work with OGC and SDW WG
… smart city topics is very broad
… ISO, IEC and JTC1, e.g., SC41 have made progress
… we've got liaison (via WoT) with ETSI/FIWARE
… property graphs from NGSI-LD
… good to know about their latest situation
… so making actual contacts with them and invite them to our calls would make sense

Kaz: we can talk with Torbjorn Lahrin who works for both the Nordic Chapter CG and JTC1

Koster: right
… we should consider system developers also

Kaz: yeah, I have contacts from Takenaka, etc.

Koster: working on smart buildings?

Kaz: right

Koster: what about ECHONET?

Kaz: these days they're working on electric power grid also

Koster: energy management is important
… could involve energy power companies also
… so we have liaison targets and will have a list of them on GitHub
… any other suggestions?

Kaz: we can generate another document about existing documents
… e.g., Mozilla's document about data governance and security

Koster: yeah

Kaz: will generate several template MDs for those topics

Hiroki: would propose we work on gap analysis too
… wondering about the scope of the survey
… survey first and then gap analysis

Koster: yeah, very good point
… along with the use cases and requirements, we can do gap analysis

AOB?

Koster: we have 2 more minutes
… any other business for today?
… the next meeting will be held in March
… we don't have many assignments so far

Kaz: after I create the GitHub repo, everybody can work hard on the content :)

Daihei: would like to share this group's aims to the publishing companies
… would be great to show them brief description about the IG

Koster: so-called "one pager"?

Daihei: yeah
… concise document about why people need to work on smart cities

Kaz: let's have some more discussion about that offline

Koster: ok
… any other business before adjourned?

(none)

Koster: thank you very much for agreeing to the one single slot!
… talk to you all in March for the next call
… please put your ideas on GitHub

[adjourned]
