We then will have breakouts. 00:36:20 After lunch we will have a report back from the break outs, followed by a joint discussion on the work plan and upcoming face to face meetings. 00:37:58 Sangchul has joined #wot 00:38:00 We will then look at the preparation of a charter for a working group and the plan for a communications task force. Finally, we will have a discussion in preparation for the joint meeting with the Internet Research Task Force Thing to Thing Research Group over the weekend in Yokohama 00:38:08 any questions? [no] 00:39:52 Topic: Status and outlook for the Thing Description Task Force 00:40:13 Johannes presents his slides, see https://www.w3.org/WoT/IG/wiki/images/b/b9/TF-AP_status_TPAC15.pdf 00:41:28 shintaro has joined #wot 00:41:35 How can a web page interact with a “thing”? We’ve worked on an object/agent based solution 00:42:04 naokis has joined #wot 00:42:40 There is binding between a client API and a resource model, along with protocol bindings, as we are fully aware that there will be different protocols according to the context 00:43:42 Johannes: we’re working on deliverables for the use cases and requirements, and a technology landscape survey 00:44:39 The latter will cover the model for things, protocol mappings, resource models, and scripting APIs and low level APIs for controller interfaces 00:45:18 … which can be used to access the hardware for sensors and actuators 00:46:39 Johannes distinguishes between a server API and a client API 00:47:15 We would like to make it easy to run scripts on different platforms though shared APIs 00:47:27 any questions? 00:47:28 q? 00:48:07 kborchers has joined #wot 00:48:21 [no questions] 00:48:35 Joerg: please tell us about the break out session for tomorrow? 00:48:41 maehama has joined #wot 00:49:13 mishizaw has joined #wot 00:49:25 Johannes: we recognise that there will be different scripting languages, so we will need to discuss the use of abstract interface definitions. 00:50:04 q+ 00:50:27 For the plugfest, people have had to create their own APIs, so we will look at what these are and how they relate to each other 00:50:54 JimB has joined #wot 00:51:00 Arnaud Le Hors (IBM): how far do you intend to go down that route? 00:51:16 taki has joined #wot 00:51:20 naokis has joined #wot 00:51:34 j_lynn has joined #wot 00:51:43 s/route?/route and how much is this in scope of the charter?/ 00:52:24 Johannes: we are using a model as a basis for comparing different solutions. We’re not trying to define a spec (since this is an Interest Group not a Working Group). We do however, want to achieve rough consensus and running code! 00:52:46 JonathanJ has joined #wot 00:53:06 present+ James Lynn 00:53:06 Joerg thanks Johannes. 00:53:36 Topic Discovery and provisioning Task force status and outlook 00:54:13 Soumya introduces himself as the lead for this task force. 00:54:57 rrsagent, draft minutes 00:54:57 I have made the request to generate http://www.w3.org/2015/10/28-wot-minutes.html kaoru 00:55:05 Present+ Jonathan_Jeon 00:55:20 He explains the need for discovery 00:57:02 … and explains how the task force has proceeded. We started with looking at the purpose and scope, ideas for simplifying discovery and a survey of existing approaches. 00:57:31 present+ James_Lynn 00:57:39 We have evaluated approaches in six categories, 00:58:30 -> https://github.com/w3c/wot/blob/master/TF-DI/Interactions.md 00:59:47 These are: finding things around 00:59:58 s/finding things around/ 01:00:12 1. finding things around me 01:00:21 2. finding things on my network 01:00:31 3. searching in directories 01:01:02 4. via accessing thing metadata (i.e. things that are dependent on other things) 01:02:00 5. searching across peers 01:02:26 We are looking for volunteers to help us refine the landscape survey with more details 01:02:58 kotakagi has joined #wot 01:03:02 wonsuk has joined #wot 01:04:05 We want to look at a uniform, technology independent abstract discovery API, and also authorisation (i.e. who is allowed to see what) 01:04:28 We are also planning on work on provisioning of devices and services 01:04:33 maehama_ has joined #wot 01:05:45 We welcome input on this 01:06:28 For the break out session, we would like to address provisioning, and the relationship to secuity and privacy. 01:06:31 negishi has joined #wot 01:07:19 We would like to look at how provisioning relates to the APIs and protocols task force 01:07:38 I want to thank Anic and others for their help 01:07:53 rrsagent, draft minutes 01:07:53 I have made the request to generate http://www.w3.org/2015/10/28-wot-minutes.html kaz 01:08:00 q? 01:08:03 wonsuk has joined #wot 01:08:27 ack A 01:08:44 q+ sebastian 01:08:48 ack s 01:08:51 questions? 01:09:19 RyutaMiyoshi_ has joined #wot 01:09:50 Dave: Note that we are looking at discovery based upon the semantics of things, and also based upon relationships between people, places and things. 01:10:09 No further questions 01:10:41 taki has left #wot 01:11:23 Joerg: in respect to the break out, the discovery task force is in a good shape. You’ve set the goal for the first draft report for the end of 2015. How do you plan the next 2 months 01:11:54 Soumya: we want to complete the landscape analysis 01:12:12 should we involve discovery based on TD for the next plugfest? 01:13:00 Soumya: yes we do 01:13:32 Topic: Thing description task force status and outlook 01:13:33 slides:https://www.w3.org/WoT/IG/wiki/images/8/82/Td_overview_sapporo.pdf 01:14:21 rrsagent, draft minutes 01:14:21 I have made the request to generate http://www.w3.org/2015/10/28-wot-minutes.html kaz 01:14:46 Sebastian introduces the motivation for thing descriptions 01:15:35 what kind of a thing is it? What kinds of data do you have? How can these be accessed? 01:16:06 We’ve looked at a range of existing approaches in our landscape survey 01:16:47 For more details, see https://www.w3.org/WoT/IG/wiki/Thing_Description 01:16:48 oonishi has joined #wot 01:18:16 The thing description framework should be scalable. Devices may be very constrained, so the descriptions should processable on resource constrained microcontrollers 01:18:34 Nono has joined #wot 01:18:45 about TD models: https://github.com/w3c/wot/blob/master/TF-TD/Tutorial.md 01:19:51 Sebastian: metadata may include information that may not be needed at run-time 01:20:41 Thing properties may be stable or dynamic. We’re looking at how to represent how stable a property is 01:20:41 ddahl_ has joined #wot 01:21:23 dhe has joined #wot 01:21:32 We also need metadata that indicates how a thing can be accessed on a given server, e.g. the protocols, data formats and encodings that server supports 01:21:42 jet has joined #wot 01:22:33 The approach is founded on the W3C Resource Description Format (RDF).
