Try /msg RRSAgent help 07:08:05 dsr has joined #wot-td 07:08:23 rrsagent, set logs public 07:08:52 meeting: Web of Things Descriptions 07:08:55 smnmyr has joined #wot-td 07:09:03 chair: Sebastian 07:09:34 Present: Dave, Dan, Ken, Louay, Simon, Soumya, Victor 07:09:43 scribenick: dsr 07:09:44 Louay has joined #wot-td 07:09:52 Joint meeting between TF-TD and TF-DI 07:11:05 Sebastian presents some slides that provide an overview of the high level requirements for thing descriptions. 07:12:27 The 3 building elements include the data model, the vocabulary and the serialisation 07:15:32 We’ve had a number of technology presentations in previous calls, e.g. IETF CoRE link format, the RDF data model, SSN ontology, JSON-LD, Spatial data ontology (SDWWG), SenML, IPSO, RDF serialisatio with EXI, Hydra (resource description), and functional semantics for WoT devices. 07:18:55 Sebastian proposes to distinguish information for identification/localisation, resource descriptions, and data descriptions. 07:20:01 How to describe what a thing does at a functional level is still a research topic 07:22:35 He presents an example of a temperature sensor located in “room 10” and which has a value in Celsius. 07:26:44 Dan: Sebastian’s approach mixes protocols and data 07:30:31 Dan talks about defining operations relating to sensors 07:38:34 Dave wonders why we aren’t talking about the simpled linked data approach as presented in earlier introductions to the web of things 07:39:01 Sebastian: we should focus on use cases to drive discussion 07:41:10 We need to plan for our face to face at the end of the month. 07:41:23 s/simpled/simple/ 07:42:02 Who of us will be in Sunnyvale? [most of us] 07:43:40 Soumya presents an overview of the work in the task force on discovery 07:45:19 Discussion on discovery in general, requirements, purpose, use cases, scopes and dimensions, and building blocks. 07:45:58 Device registation and lifecycle 07:46:40 4 categories: beacon based, discover on my network, searching in directories, and metadata 07:47:52 jhund has joined #wot-td 07:48:59 [Dave notes that this discussion omits disccovery based upon social connections, and also thingsonomies] 07:49:45 Soumya: we want a common vocabulary for thing description and discovery 07:51:56 Sebastian: Soumya, what do you mean by registration, how would it work? 07:52:12 In particular, how does a device know where to register? 07:52:57 Soumya: the registry location could be hard coded into the device’s software 07:53:50 [Dave: or the device could first discover a registry, e.g. a hub on the local network] 07:54:11 Soumya: devices can advertise themselves e.g. via Bluetooth beacons 07:55:01 IPSO have a specific vocabulary for things to identify themselves with 07:58:28 Victor: when you’re searching directories, how do you specify the scope? 07:59:30 Soumya: excellent question. We can have a local and remote scope. 08:00:21 Victor: you mean local networks? 08:00:24 Soumya: yes 08:01:37 Victor: what about sensor networks? 08:03:26 Dave: there are many possibilities, e.g. peer to peer based queries 08:03:58 Soumya invites Victor to join the discovery task force 08:04:37 Sebastian sums up and sets his expectations for the face to face. 08:05:00 … end of meeting 08:05:11 rrsagent, make minutes 08:05:11 I have made the request to generate http://www.w3.org/2015/07/08-wot-td-minutes.html dsr 09:14:18 Zakim has left #wot-td 09:49:33 dsr has joined #wot-td 10:34:04 dsr has joined #wot-td 12:37:02 dsr has joined #wot-td
