Logistics

Plugfest logistics

Kaz: think we can ask people about their updates
… and then ask them to add the updates to their ideas on the GitHub page

Koster: yeah

Kaz: ECHONET can provide the same devices they provided for WoT Week last year

Koster: need a dedicated bridge?

Kaz: they themselves should be able to provide one for WoT connection

Ege: what to be checked for ECHONET Lite Web API devices?
… would see the possible binding based on the WoT Binding Template mechanism

Kaz: yeah, you can propose it :)
… let's create a subsection under the "Proposed topics" and start concrete discussion

Ege: regarding the third bullet, interested in WoT Registry
… also regarding the "Demo devices" table, should add concrete information. right?

Kaz: yes
… will ask the ECHONET guys about their devices
… you can also put your devices to the table

Possible Topics

Koster: we already have ECHONET Lite Web API as a possible topic

Ege: would clarify what we expect specifically from external SDOs

Kaz: I'll create sub sections for the "Proposed topic", and then you all can put your expectations to each section

Ege: btw, we should use one-level upper layer for the folder, which we used for WoT Week?

Kaz: we use this "Plugfest" layer for TPAC Plugfests, but I'm OK to moving this README to one-level upper layer

Ege: would ask the others about their ideas also

David: like last year we discovered, look at the group
… want to see what would happen
… e.g., questions about security and interoperability for retail operations

Ege: need to get connected with the others?

David: like last year, there would be somebody :)

Ege: so interoperability of the Conexxus devices with others

Koster: you already have actual specs on your side

David: would also see Binding and Profile
… hopefully will be what people would think

Koster: yeah
… would ask people for opinions around both the mechanisms

Ege: we had problem with checking Profile due to the network connection?

David: by the time early next year, we'll publish our new spec
… to work with both Binding and Profile

Ege: please note that Binding or Profile is not a normative spec

David: but still gives directions for us for interoperability
… need to do this kind of work

Kaz: great!
… please put your ideas to the subsections
… just to make sure, I'll bring the wot-testing/events/plugfest/2025-tpac-kobe/README.md to wot-testing/events/2025-tpac-kobe/README.md

Ege: ok

David: will have the Conexxus Show in Chicago in October

Kaz: so you can bring something based on the demo there to TPAC :)

David: yeah
… would be confident about the milestone

Koster: what else?

Ege: would ask Toumura-san about his ideas also

Toumura: would try some tooling
… get connected with people's devices

Ege: some kind of mash-up

Toumura: yeah

Ege: David is interested the retail domain
… but Toumura-san is interested in more generic mechanism

Kaz: in that case, having "Demo devices" is not really appropriate
… and can be included in the "Topics" section
… also we can describe possible applications

Ege: exactly
… can add those changes

Kaz: in that case, you can move the file to the events layer also :)

Ege: btw, what about the last two topics?
… OCPP and NGSI-LD

David: no
… don't think we have a demonstration about that at the moment

Kaz: let's keep the current list, and also add a specific subsection under the list

Koster: agree

Next Steps

Kaz: can move the README.md to the events layer with the proposed changes quickly

Ege: actually, already created a PR for the current README.md...

Kaz: in that case, we can quickly review it and then I can work on further improvement
… then people can work on their proposals

Koster: ok

Ege's PR 617 - Add more specific topics

Koster: any objections?

(none)

merged

Kaz: will work on further improvements, and then let you all know once it's done

Koster: ok
… anything else for today?

(none)
