- 12:24:07 [Yingying]
- Yingying has joined #wot
- 12:24:49 [VictorCharpenay]
- Louay: column for discovery. Still a bit early to tell what kind of discovery we want to setup during the plugfest.
- 12:25:51 [VictorCharpenay]
- Johannes: last time, was a central discovery with self-registration to a server (see webthing-repository on Github)
- 12:26:09 [VictorCharpenay]
- thingweb-repository*
- 12:27:10 [VictorCharpenay]
- Louay: my own demo will offer 3 discovery mechanisms. How a client will know which one(s) is (are) available
- 12:27:25 [VictorCharpenay]
- Johannes: How-to needed?
- 12:28:08 [VictorCharpenay]
- Sebastian: Feedback from last time: common vocabulary needed. Discovery should rely on that.
- 12:29:58 [Yingying]
- Yingying has joined #wot
- 12:31:04 [VictorCharpenay]
- Louay: also important. Example of SSDP: SSDP requests (similar to UDP request) and response with some links? What should be the content of the requests? Should the response contain link to the Thing Description, something else?
- 12:31:16 [Yingying]
- rrsagent, make minutes
- 12:31:16 [RRSAgent]
- I have made the request to generate http://www.w3.org/2016/03/16-wot-minutes.html Yingying
- 12:31:18 [VictorCharpenay]
- Indeed, how-to/discussion needed.
- 12:33:06 [VictorCharpenay]
- Soumya: als wants to have a mDNS client, we should synchronize.
- 12:33:42 [kaz]
- kaz has joined #wot
- 12:34:16 [VictorCharpenay]
- Johannes: this how-to should be included in the Current Practice document (http://w3c.github.io/wot/current-practices/wot-practices.html)
- 12:34:47 [VictorCharpenay]
- Sebastian: discussion about a common vocab should also start now.
- 12:35:15 [VictorCharpenay]
- Darko: we could use the Scenario table to foresee which concepts are needed.
- 12:37:31 [VictorCharpenay]
- Johannes: further topics about the F2F?
- 12:38:03 [VictorCharpenay]
- Soumya: in the agenda, joint breakout sessions. Should it be prepared by each TF?
- 12:39:04 [VictorCharpenay]
- Johannes: would make sense. Topics should be collected directly on the wiki page.

- 12:51:33 [VictorCharpenay]
- s/see Current Practice document/Sebastian: see Current Practice document/
- 12:52:39 [VictorCharpenay]
- new structure based on feedback from last time.
- 12:52:47 [VictorCharpenay]
- 1. "href", new term to indicate how to access the Thing's properties, events, events.
- 12:53:08 [VictorCharpenay]
- 2. removed "metadata". Instead metadata fields directly in the root object
- 12:53:17 [kaz]

- q+
- 12:53:47 [kaz]
- q?
- 12:54:06 [VictorCharpenay]
- Michael: clarification: intended to use standard URI rules (like concatenation of base URI and localname)?
- 12:54:06 [Zakim]
- Zakim has joined #wot
- 12:54:17 [kaz]
- q+ jhund
- 12:54:28 [VictorCharpenay]
- (example was "href": "temp")
- 12:55:22 [dape]
- q+
- 12:55:47 [VictorCharpenay]
- those rules are defined in RFC 3986
- 12:56:28 [toru]
- present+ Toru_Kawaguchi
- 12:56:44 [VictorCharpenay]
- something that would be needed is to have composite Things

- 12:59:22 [kaz]
- q?
- 12:59:45 [VictorCharpenay]
- Victor: it has been added to the TD vocabulary: "associatedThing", to link different Things with each other
- 13:00:07 [jhund]
- ack jhund
- 13:00:13 [VictorCharpenay]
- Johannes: other comment about mandatory and optional fields
- 13:00:30 [Soumya]
- I have to leave now, but I have experience the same Michael mentioned. I considered them as M2M device having several endpoints and described the device and endpoints seperately.
- 13:00:44 [Soumya]
- I can talk on this later if required
- 13:00:51 [Soumya]
- Bye for now
- 13:00:53 [VictorCharpenay]
- Sebastian: all this should be added in the Current Practice document
- 13:01:20 [VictorCharpenay]
- Soumya and Johannes agree with Michael
- 13:03:47 [VictorCharpenay]
- Johannes: TD is the blueprint of how to communicate with the Thing. Not known beforehand. Need for TD "template§?
- 13:04:03 [VictorCharpenay]
- s/"template§/"template"
- 13:04:17 [VictorCharpenay]
- s/"template§/"template"/
- 13:05:52 [VictorCharpenay]
- Darko: similar to the difference between class and instance. Using classes/templates could increase interoperability
- 13:05:53 [jhund]
- q?
- 13:06:20 [Sebastian]
- ack dape
- 13:07:18 [VictorCharpenay]
- Daniel: about Michael's question about "href". In case of URI arrays, cartesian product or one-to-one mapping?
- 13:08:17 [VictorCharpenay]
- Michael: definitely not in the RFC. Should have a kind of "map" of base URIs
- 13:09:23 [VictorCharpenay]
- where each base URI fits
- 13:09:51 [VictorCharpenay]
- Daniel: what if the resource structure is different depending on the scheme (HTTP, CoAP)?
- 13:10:45 [Sebastian]
- ack Soumya
- 13:11:33 [VictorCharpenay]
- Michael: chance of having such a situation?
- 13:12:10 [VictorCharpenay]
- Sebastian: this was about TD core. There's also the possibility to extend a TD with other vocabularies.
- 13:12:23 [VictorCharpenay]
- Darko will present this part
- 13:13:32 [VictorCharpenay]
- Darko: 1. machine-readable -> defined term in vocabs already available.
- 13:14:33 [VictorCharpenay]
- 2. aditional properties to describe a Thing? Provided in an extended context, as shown in Example 2 of the Current Practice doc.
- 13:15:02 [VictorCharpenay]
- Ex: "@type": "sensor:Temperature"
- 13:15:16 [VictorCharpenay]
- or "sensor:unit": "sensor:Celsius"
- 13:16:40 [MIchael]
- q+
- 13:17:13 [VictorCharpenay]
- Michael: it really makes sense to do such things.
- 13:18:14 [VictorCharpenay]
- have you tried to convert JSON-LD into RDF triples?
- 13:21:24 [VictorCharpenay]
- Darko: by the way, we have much better TDs if we start from RDF and turn them afterwards into JSON-LD than writing it directly in JSON-LD
- 13:22:10 [VictorCharpenay]
- Michael: things would be easier if we put as many things in the context, maybe?
- 13:23:13 [VictorCharpenay]
- Darko: want to standardize TD, we shouldn't re-standardize existing vocabs (such as units, quantity kinds)
- 13:25:43 [VictorCharpenay]
- way to go -> one TD context + one horizontal context for common concepts like units?
- 13:26:32 [VictorCharpenay]
- Sebastian: moving on to the next example of a TD (see Current Practices)
- 13:27:21 [VictorCharpenay]
- "uri", "decodings". And "security": requirements to access Thing's resources
- 13:27:30 [jhund]
- ack MIchael
- 13:27:58 [VictorCharpenay]
- self-contained. Example 3 shows auth with JSON Web Token (JWT).
- 13:30:42 [VictorCharpenay]
- A lot of new things, details to be found on the document. Comments welcome.
- 13:31:49 [VictorCharpenay]
- other questions about the TD?
- 13:32:30 [VictorCharpenay]
