13:14:29 [DarkoAnicic]

Sebastian: ThingWeb Repository was introduced by Plugfest

13:14:56 [TuanTranNhat]

TuanTranNhat has joined #wot-td

13:14:56 [DarkoAnicic]

Sebastian: stores TDs from all demos, it can be queried, updated etc.

13:16:15 [DarkoAnicic]

Sebastian: T2T introduction has been demonstrated (temperature sensor form France interacts with an aircondition device from Japan)

13:17:39 [DarkoAnicic]

Sebastian: various demonstrations were presented, with more TDs than in Sapporo. Various supported protocols, e.g., HTTP, CoAP, MQTT, WS

13:19:06 [DarkoAnicic]

Sebastian: feedback from Pkugfest: change of IP address should be kept up to date in the Thing's TD.

13:19:34 [DarkoAnicic]

Sebastian: there was a question about the support for security in TD

13:20:31 [TuanTranNhat]

present+ TuanTranNhat

13:21:03 [DarkoAnicic]

Sebastian: further on, binding to the protocols. We add a property name to the IP addtress (uri). We could work on a better prosal here, e.g., HATEOAS

13:22:03 [DarkoAnicic]

Sebastian: how to nest properties, how to handle absolute links (further open questions in the scope of TD-TF)

13:23:09 [DarkoAnicic]

Sebastian: TD provides a basic semantic info, but the real semantics can be captured in higher-level vocabularies, ontologies etc. How to integrate and utilize them?

13:23:35 [DarkoAnicic]

Sebastian: TechLandscpae wasa topic too

Victor: Schema.org is not tightly related to TD

13:31:04 [pablo]

pablo has joined #wot-td

13:31:16 [DarkoAnicic]

Michale: agree, but can serve as as an example of a shared vocabulary used on the Web, and perheps we could do similar things related to WoT

13:32:15 [DarkoAnicic]

Sebastian: for further propsoals on the TechLandscape, please propose via email

13:38:49 [DarkoAnicic]

Sebastian: a joint TD - SP session

13:39:50 [DarkoAnicic]

Sebastian: whether and how to put security related information in TD

13:40:56 [DarkoAnicic]

Sebastian: outcome: let us create examples of TDs with security related information, e.g., relaying on JSON Web token

13:41:29 [DarkoAnicic]

Topic: 3rd day of F2F - Break Out day

13:42:22 [DarkoAnicic]

Sebastian: Darko presented an example how to extend a TD (for a brightness sensor used in the Plugfest) with further contextual infomration (e.g., SSN ontology)

13:43:01 [DarkoAnicic]

Sebastian: discussion was whether we could extend vocabulary in TD-TF

13:43:47 [DarkoAnicic]

e.g., horizontal vocabular, i.e., not domain dependent. For example, for "on" and "off"

13:44:48 [DarkoAnicic]

Sebastian: presents outcome of the discussion on what is in the scope of the future WG w.r.t TD-TF

13:47:37 [DarkoAnicic]

Darko: regarding a horizontal vocabulary we could try to propose one and use it during our Plugfests, and if it turns to be useful and practical, then it could be a subject of the group's work

13:48:19 [DarkoAnicic]

Sebastian: no new serilization format should be proposaed by us, i.e., we should relay on the existing ones

13:50:03 [DarkoAnicic]

Johannes: system internal and generation of TD in the scope of AP-TF

13:50:54 [DarkoAnicic]

s/serilization/serialization/

13:51:21 [DarkoAnicic]

Frank: the meeting was very productive

13:52:56 [DarkoAnicic]

Frank: we cannot propose only one serialization format, the standard needs to be opened for various fomrats

13:53:45 [DarkoAnicic]

Matthias: content negotiation mechanism should be used

13:55:08 [DarkoAnicic]

Johannes: for existing APIs the question is whether I will be able to create a TD - is this in the scope of the group's work?

13:56:03 [DarkoAnicic]

Matthias: for legacy systems, a gateway can be used

13:59:35 [DarkoAnicic]

Sebastian: if one creates an API that is compliant with guidelines from us (API-TF), then there should be no problem. Exisitng systems that do not relay on such guidelines, can use gateways. However this is out of scope of the group's work.

14:00:13 [DarkoAnicic]

Sebastian: you can still comment on subjects that are in/out of scope via emails

14:00:56 [DarkoAnicic]

Sebastian: first to address is the subject on protocol bindings and planning for the next Plugfest

14:01:55 [DarkoAnicic]

Mohammed: what is the conclusion on the presentation about oneM2M

14:02:56 [DarkoAnicic]

Sebastian: it was a nice overview, the presented ontology is very interesting, although quite big

14:03:16 [DarkoAnicic]

Sebastian: could be a good input for a colaboration with us

14:04:49 [DarkoAnicic]

Johannes: possible colaboration on the level of abstraction between oneM2M and the API work, but oneM2M activities are more related the TD-TF

14:06:55 [DarkoAnicic]

Michael: IoT semantic interopearbility workshop in March will be held in Silicon Valley. Everyone invited, please send a position paper.

14:07:23 [DarkoAnicic]

s/in March will be held/will be held in March/

14:09:35 [DarkoAnicic]

Michael: it would be valuable to have a position of oneM2M at the workshop

14:10:07 [DarkoAnicic]

Sebastian: please work on the TechLandscape, see you in 2 weekes.
