WoT TPAC wiki

Lagally: (goes through the TPAC wiki above)
… what should be presented about use cases there?

wot-usecases doc

Lagally: we have domain-specific use cases (and horizontal ones) within the use cases document above
… there is a section about "retail" as well
… let's pick up some of the domains during TPAC vF2F

David: when to have the discussion?

Lagally: not scheduled yet
… any preference?

David: Jack and myself will be out for another event next week

Lagally: (goes through the schedule)

Kaz: any preferred date?
… 26?

<mlagally> 1Prefered UC slot during TPAC: 2:00 UTC on Tuesday, Oct 26th

Lagally: ok
… also some update on Takenaka and WoT-JP CG

Kaz: ok

PR 131 - Cultural Spaces (Museums) use case

… other than that, would merge this PR
… any objections?

(none; merged)

Issues

Issue 135

Issue 135 - Improve references: Use Specref Database references where available for release 2.0

Lagally: some trouble with Specref
… (goes through the Specref entries)
… would like to continue to work on "publication-2.0" issues

Kaz: that means "next publication". right?

Lagally: yes

<mlagally> https://github.com/w3c/wot-usecases/issues?q=is%3Aissue+is%3Aopen+label%3Apublication-2.0

Lagally: those issues marked as "publication-2.0" above

Retail use cases

Lagally: any high-level introduction?

David: as we develop based on user story
… one of our outcome should be to figure out what would be useful for people
… one of the biggest problems
… a lot of aspects might be important
… one of the things is
… controlling a device in a concrete use case
… e.g., your freezers
… how to hook up things
… interfering things
… we've done our best to justify why given device might need to be standardized
… ecosystem to accomplish some task
… controlling single freezer is not nearly that important
… the store operation, etc., related to the merchants' need

Jack: things related to spoil edge

David: how to do categorization is another question

Kaz: based on geolocation information?

Lagally: would it make sense to have discussion by a smaller group?
… including Michael McCool
… thought there was some ZIP file

David: you can share the resource here
… (shares the information on Conexxus Use Cases - first draft)
… let me see the original document
… (shows the original document)
… sales-related devices
… facilities, data and power equipment
… food preparation and food service devices
… classification field to categorize the devices

Lagally: wondering about "indoor and outdoor freezers" and "kitchen refrigerator"

Jack: a little bit of overlap and some more differences

Lagally: maybe we can pick up some key use cases
… or do we want to categorize them with some fine-grained categories?

David: (shows a use case description)

Jack: yeah, this is an actual use case

David: no outdoor refrigerator here
… let me provide one
… btw, this list of devices is more useful

Lagally: looks a good categorization
… about a gas station?

David: typically :)

Lagally: why don't you create Pullrequests based on the use cases?

David: wondering about category and class
… how to use the "Class"?

Lagally: we've not used it yet

David: can we use the "Class" field to clarify the details?

Lagally: sounds good

David: would provide a use case for the Oct 26 meeting

Lagally: 5 stories under one use case are mentioned here (within the device list)

David: maybe one-page presentation on our situation
… in 10 minutes

Lagally: during the Oct-26 meeting?

David: yes

Lagally: ok
… my question is what/how to review the proposals

David: may remove the classification of indoor/outdoor

Jack: makes sense

Kaz: think you can use the "Category" field for "Retail"
… and use the "Class" field to show actual categorization of your use cases

David: ok
… can do within a few days

Lagally: and some more discussion/review including McCool?

David: ok

Lagally: you can create Pullrequests as well

David: how about aiming 19th?

Lagally: ok

Kaz: nice
… we can start with one specific use case
… and use the "Variants" field to show possible variants

Lagally: let's continue the discussion by email

Kaz: so on 19th possible initial use case description
… and then on 26th actual use case discussion during TPAC vF2F with one pager slide

all: yes

Lagally: aob?
