- 22:51:00 [Zakim]
- kaz, you wanted to ask (1) any gateway between tv and UI, and (2) how to specify the rules
- 22:51:18 [McCool]
- kaz: wondering abuot connection mechanism;
- 22:51:29 [McCool]
- ... but can you go back to connections diagram, slide 9
- 22:51:39 [McCool]
- ... use have a user app as the WoT consumer
- 22:51:54 [McCool]
- ... air cleaner is a Thing, using ECHONET
- 22:52:20 [McCool]
- ... what is the hybridcast TV itself? Is it an app?
- 22:52:24 [dezell]
- q+ to remark on similarities of the roles between "Hybridcast Connect" and "Home Assistant" in two demos.
- 22:52:58 [McCool]
- mm: there is a TD for the TV, so is it a Thing?
- 22:53:21 [McCool]
- endo: in this demo scenario, tv can emit information only
- 22:53:59 [McCool]
- kaz: so tv could also automatically repeat based on noise, for example?
- 22:54:39 [McCool]
- kaz: second question, was how to specify rules
- 22:55:04 [McCool]
- ... depending on the user application? just using node-RED? JS? What is your model?
- 22:55:23 [McCool]
- endo: this demo is just a very simple if-then algorithm
- 22:56:09 [kaz]
- q?
- 22:56:18 [kaz]
- scribenick: kaz
- 22:56:33 [kaz]
- mm: required by user requiring rules
- 22:57:04 [kaz]
- ... maybe the smart tv can make prompt to the user asking what to do
- 22:57:10 [kaz]
- ... potentially
- 22:57:27 [kaz]
- endo: yes, that's possible
- 22:57:50 [kaz]
- ... this time we used simple replay scenario but some kind of schema model could be applied
- 22:58:12 [kaz]
- ... and the use app can catch user's input
- 22:58:27 [kaz]
- mm: question for Toumura-san then
- 22:58:35 [kaz]
- ... could you please pick up your slides?
- 22:58:50 [kaz]
- ... local area network applications
- 22:58:59 [kaz]
- ... how to make that unique?
- 22:59:10 [kaz]
- ... you're using URN as an ID
- 22:59:18 [pchampin]
- pchampin has joined #wot-demo
- 22:59:18 [kaz]
- ... also allows DID
- 22:59:37 [kaz]
- ... what can be used instead of HTTP URL?
- 22:59:53 [kaz]
- ... raising an interesting point
- 23:00:08 [kaz]
- ... related to an issue on global DNS and CA
- 23:00:22 [kaz]
- kt: difficult to handle local network id
- 23:00:57 [kaz]
- mm: hostname is also kind of dangerous
- 23:01:06 [kaz]
- ... need to avoid collisions
- 23:01:37 [kaz]
- kt: if we use some random ID, would get another kind of problem
- 23:01:40 [kaz]
- mm: right
- 23:01:55 [kaz]
- ... let's have more discussion about IDs
- 23:02:08 [kaz]
- ... HTTPS on browsers depend on CAs

- 23:02:47 [kaz]
- de: great demos
- 23:02:54 [kaz]
- ... sort of same pattern
- 23:03:10 [kaz]
- ... more or less, smart assistant as home gateway
- 23:03:27 [kaz]
- ... Endo-san used Node RED
- 23:03:32 [kaz]
- ... that patter makes sense
- 23:03:43 [kaz]
- ... Node RED plays important role
- 23:03:48 [kaz]
- s/role/role for WoT/
- 23:03:57 [kaz]
- ... the other thing
- 23:04:33 [kaz]
- ... a question about how this mechanism works with browsers
- 23:04:57 [kaz]
- ... collaboration would be nice
- 23:05:00 [kaz]
- q+
- 23:05:27 [kaz]
- mm: we need to look at trust management, etc.
- 23:06:06 [kaz]
- kaz: and we should continue with the DAS WG guys as well :)
