12:12:48 <victor> Dave: attended one day, developer oriented side event.
12:13:25 <victor> security and shared semantics seemed to be an important concern.
12:14:36 <victor> about the main event, I was invited in a plenary session. A lot of interest for WoT.
12:14:37 <stakagi> stakagi has joined #wot
12:15:32 <kaz> i/IoT TechExpo/yingying: we'll have a separate call with CETC, the host of the Beijing f2f meeting/
12:15:33 <victor> Sebastian: how do we bring all interested people to the group?
12:15:51 <victor> Especially about security.
12:16:16 <victor> Dave: maybe a white paper gathering the challenges of WoT would help.
12:17:14 <victor> topic: WG charter
12:17:25 <kaz> -> http://w3c.github.io/wot/charters/wot-wg-2016.html WG Charter
12:17:25 <victor> Sebastian: next week, discussions will be close.
12:17:41 <victor> one pending issue.
12:18:21 <victor> topic: PlugFest preparation
12:18:54 <kaz> -> https://www.w3.org/WoT/IG/wiki/F2F_meeting,_July_2016,_China,_Beijing#PlugFest PlugFest wiki
12:19:14 <kaz> -> http://w3c.github.io/wot/current-practices/wot-practices.html Current Practices document
12:20:03 <victor> Current Practices document is supposed to provide an overall introduction to our activites.
12:20:21 <kaz> i|PlugFest preparation|-> https://github.com/w3c/wot/issues/174 Issue-174|
12:20:39 <victor> reviewed the last days by Taki, Matthias and Sebastian. Still missing elements.
12:21:12 <victor> first section: Protocol bindings (Matthias)
12:21:30 <victor> concrete bindings for MQTT, BLE and WebSocket missing
12:21:53 <victor> volunteers needed
12:22:26 <michael> q+
12:22:53 <victor> Dave: spoke with Louay yesterday. He might be able to help.
12:23:16 <victor> myself could help for WebSocket
12:23:57 <kaz> ack mi
12:24:37 <victor> Michael: started to work on MQTT (related to the abstract layer proposal). I could contribute for MQTT.

12:25:22 <kaz> present+ Katsuyoshi
12:26:48 <victor> Sebastian: reviews mentioned, among others, lack of clarity for the TD context question and integration of external semantics secton empty.
12:27:01 <victor> Victor: submitted a pull request to address that.
12:27:47 <kaz> -> https://github.com/w3c/wot/pull/195 Victor's pr
12:27:51 <victor> Sebastian: what's new is Taki's section about the type system for TD.
12:28:13 <dsr> q+
12:28:46 <victor> JSON Schema is not the perfect solution and certainly no definitive one.
12:28:54 <dsr> ack ds
12:32:11 <kaz> -> https://github.com/w3c/wot/tree/master/proposals/type-system Type System discussion
12:33:04 <victor> Dave: should also reference other proposals for a type system.
12:34:01 <michael> q+
12:34:03 <victor> Victor: a link to the type system discussion should be added, indeed.
12:34:55 <kaz> q+
12:36:50 <victor> Victor: Taki, could you do that?
12:37:01 <dsr> Dave’s notes are at https://github.com/w3c/web-of-things-framework/blob/master/documents/things.md
12:37:26 <kaz> q?
12:37:41 <dsr> ack mich
12:38:26 <dsr> + 1 to Michael’s work on schema.org for IoT metadata
12:38:45 <victor> Michael: there was also a proposal to use schema.org for the type system. It seems inappropriate.
12:39:19 <victor> we'd better use it for *external* semantics.
12:39:20 <jhund> q+
12:40:32 <dsr> q+
12:41:51 <dsr> ack kaz
12:41:51 <victor> we should remove the schema.org column in the type system discussion.
12:42:00 <victor> Victor: I'll do that.
12:42:38 <victor> Kaz: A section about types should be added to the Tech Landscape document.
12:42:58 <kaz> -> https://w3c.github.io/wot/landscape.html Tech Landscape document
12:43:28 <dsr> ack jh
12:44:05 <victor> Sebastian: Dave, can you add your part to the tech landscape?
12:44:21 <victor> Dave: I will.
12:45:02 <dsr> ack dsr
12:45:06 <jhund> ack dsr
12:45:42 <victor> Johannes: Agree with Kaz. The Tech Landscape document is perfect for that purpose. The tech landscape activity vs. current practices activity should really be separated.
12:46:29 <victor> I mean, picking one technology in particular for PlugFest doest not prevent us from investigating further and extend the tech landscape.
12:50:48 <victor> Michael: JSON schema and schema.org could be both used, actually for they address different things
12:53:10 <victor> Sebastian: we will discuss this in breakout sessions in Beijing. We will start with the issues Dave raised regarding JSON schema
12:54:15 <DarkoAnicic> q+
12:54:16 <victor> Dave: what often comes up when speaking with developers is the need for *ligth-weight* semantics
12:55:08 <victor> Darko: question to Dave: are we talking about extending schema.org or creating a WoT semantic framework?
12:58:08 <victor> Dave: it is an important discussion we should have in Beijing. What process should we follow to register/validate new concepts?
12:59:24 <victor> Sebastian: end of the type system section.
12:59:35 <victor> next section: discovery
13:00:27 <victor> Soumya is not in the call to comment. Matthias suggested this section wasn't clear enough
13:01:54 <victor> should we still try to integrate Louay and Dave's proposal for the next PlugFest or stick to a centralized "semantic-based" approach through the Thing Repository?
13:03:31 <victor> Dave: simple question: will we have this repository running locally in Beijing?
13:04:50 <victor> Michael: I think there is an action item for the repository
13:06:37 <victor> Victor: I'll check we can have a completely local version of the repository (issue with external JSON-LD contexts)
13:07:40 <kaz> q?
13:07:56 <kaz> ack d
13:08:16 <victor> Dave: it is simple enough to register with mDNS or SSDP but we have to be sure we'll have time to address this properly.
13:08:54 <victor> Sebastian: we'll try to provide at least the repository
13:09:21 <victor> next CP section: section
13:09:39 <victor> s/: section/: security
13:10:26 <victor> Sebastian: someone willing to contribute for that section?
13:11:56 <victor> Toru: Panasonic followed Oliver's instructions. New approach for this PlugFest? If not, we can copy Oliver's instructions in the doc.
13:12:40 <victor> Sebastian: I'll try to ask Oliver.
13:13:01 <victor> next section: scripting API
13:13:47 <katsu> katsu has joined #wot
13:13:58 <victor> Johannes: some changes on the API, currently a proposal on Github. More consistent, especially for the server-side.
13:15:25 <victor> should merge it in the CP document. Would like to have Louay's feedback first. Should als translate the proposal into webIDL first
13:15:45 <kaz> -> https://github.com/w3c/wot/issues/173 Issue-173
13:16:00 <victor> comment on issue #173 are welcome
13:16:21 <kaz> s/comment/Johannes: comment/
13:17:17 <victor> Dave: it depends on the language used. The API might not fit dynamically typed languages.
13:19:03 <victor> the idea is to have a minimal basis + syntactic suger for a particular language (see e.g.  DOM vs. jQuery).
13:20:06 <victor> e.g. discussion about using constructors or factories. There is nothing preventing you from adding language specificities.
13:20:52 <victor> expect to reach out to more people. For instance the author of the Generic Sensor API
13:24:40 <victor> Sebastian: what is still needed is a description of semantic extension mechanisms in the TD.
13:26:53 <victor> Victor: my last PR also has a few changes in this section.
13:27:07 <victor> Darko: I'll also have a look at this section.
13:28:11 <victor> Michael: I have started using external semantics btw. Details in the mailing list.
13:28:37 <victor> topic: online Things
13:28:55 <victor> Johannes: some WoT simulators are available online
13:29:15 <victor> without concrete behaviour, though.
13:29:42 <victor> anybody else having Things exposed in the Web?
13:30:13 <victor> It would be interesting for testing
13:30:28 <victor> topic: next Web meeting
13:30:54 <victor> topics to add to the agenda:
13:31:01 <victor>  1. WG charter
13:32:13 <victor>  2. CETC presentation (separated Web call next Tuesday, 9-10am)
13:33:10 <victor> Toru: what is the purpose of this pres?
13:34:08 <victor> Yingying: presentation of some implementation related to IoT Alliance. Focus on interop. How to combine it with our PlugFest
