"platform" uri. and "sink". streaming properties provides blocks of data. 07:42:15 DR: Showing nested properties. 07:44:21 DP: You colected all the use cases. 07:44:54 DP: RDF, turtle, JSON mapping. Is it similar to what we are doing? 07:45:06 DR: I use RDF as the model. 07:45:19 DP: OK, it seems similar to what we do. 07:45:19 s/colected/collected/ 07:45:40 DP: Some people does not seem to like RDF. 07:45:50 DR: It depends on the audience. 07:46:56 DP: You seem to have different type system. 07:47:06 DP: How should we converge them? 07:47:35 DR: I looked at more use cases. We need some more such as union, enumerations, collections and vectors. 07:48:00 DR: Numbers vs integers. 07:48:21 DP: Schema also supports some of them. 07:48:38 DR: OCF and OneM2M use cases requires some more. 07:49:06 DR: It is not really good at descrining linked data. 07:49:47 Sebastian: 80% of the use cases, I think we can use JSON-schema. 07:49:59 DR: That is not true. 07:51:14 DR: meta-data is critical. 07:51:54 victor has joined #wot-td 07:51:59 Sebastian: We would like to rely on existing technologies. 07:52:50 Sebastian: Matthias mentioned JSON-schema standardization members will join face-to-face meeting. We can collaborate with them. 07:53:13 DR: We have to address broad range of communities, we have to bear in mind. 07:53:29 DR: By the time of face-to-face, I will do more analysis. 07:53:35 q? 07:53:39 ack dape 07:54:31 DR: OPC uses their own modeling, similar to RDF. 07:54:41 DR: Healthcare is another use case. 07:54:48 ack k 07:54:48 kaz, you wanted to ask about (1) unit and type and (2) if we want to include the figure/idea of "app contracts" to the architecture doc 07:55:28 KA: How to handle datatype. We can consider JSON-schema. 07:55:54 KA: New diagrams. IoT platform contracts. 07:56:16 KA: IoT platform contracts. Is it different from protocol mapping? 07:56:22 DR: Yes 07:56:45 KA: Application contracts. Is it TD and Scripting? 07:57:22 KA: You mean various application languages? 07:57:31 DR: JavaScript, Java, whatever. 07:57:55 DR: Our scope was abstraction layer, I believe. 07:58:03 s/DR/KA/ 07:58:26 DR: We also need security, provacy, etc. Non-functionals. 07:58:37 DR: Contracts between applications. 07:59:00 -> https://www.w3.org/TR/2016/WD-vehicle-information-service-20161020/images/W3C_Vehicle_APIs_Component_Diagram_v1_3.png automotive architecture 07:59:54 KA: I am not saying your diagram does not make sense. 08:00:16 KA: It seems as if this approach is similar to automotive architecture. 08:01:33 KA: Application contracts layer includes WebSocket interactions. 08:01:53 KA: Then this approach is a bit different from the current architecture. 08:02:01 DR: I believe it is same. 08:02:11 KA: Mechanism seems different. 08:02:27 DR: Current architecture is less about layering. 08:03:11 DR: I have coordinated with OneM2M, OCF. But the work was mostly done by myself. 08:04:28 Sebastian: Thank you Dave. 08:04:40 Sebastian: Plugfest. 08:04:59 Sebastian: TOPIC: Plugfest 08:05:01 s/layer includes/layer possibly includes/ 08:05:51 Sebastian: Showing WoT features list... 08:06:02 Sebastian: We have testcases. 08:06:32 Sebastian: We can go through the list during plugfest. 08:06:52 i/Sebastian: Plugfest/topic: PlugFest/ 08:06:53 Sebastian: For example, discover things, read properties, etc. 08:07:25 i/Thank you Dave/[ Maybe a good topic for the OCF liaison call :) ]/ 08:08:12 Sebastian: It would be nice to use table to find what is working and what is not working. 08:08:34 q? 08:09:09 present+ Victor 08:09:24 q+ to ask if this check list is online 08:10:01 Sebastian: Let's discuss later during main telecon. 08:10:10 ack k 08:10:10 kaz, you wanted to ask if this check list is online 08:10:14 q+ 08:10:22 https://github.com/w3c/wot/blob/master/plugfest/2016-beijing/TestCaseCoverage.xlsx 08:10:32 TK: Sorry I did not ask Nimura-san what he will bring to face-to-face. 08:10:32 ack v 08:11:02 http://json-ld.org/spec/latest/json-ld/ 08:11:19 victor: I wanted to mention that JSON-LD spec was updated recently. 08:11:35 voctor: I want to discuss this during face-to-face. 08:11:54 Sebastian: Mr. Kellogg will come to face-to-face. 08:12:06 s/voctor/victor/ 08:13:24 KA: Is this a draft report, right? 08:13:29 victor: yes. 08:13:42 s/this/this ver. 1.1/ 08:13:44 victor: it will stay as a community group report. 08:13:57 s/draft/draft CG/ 08:14:33 victor: Dave is trying to specify. The similar is also formalized in the document. 08:14:51 victor: therefore, it is worth taking a look at it. 08:14:57 -> http://json-ld.org/spec/latest/json-ld/#relationship-to-rdf 7.
