12:27:57 <victor> Daniel: three proposals. JSON Schema is the best so far.
12:28:29 <mkovatsc_> q?
12:28:37 <kaz> q+
12:28:42 <victor> There are a few pending issues but we'll start to integrate the outcome of this task to the current practice document.

12:30:22 <victor> Daniel: JSON Schema allows: integer, min, max, float. No way to say e.g. [0.1, 0.2], though
12:30:41 <victor> Kaz: should discuss the details at the F2F.

12:31:26 <victor> Matthias: JSON Schema is still a draft. We should take advantage of this to drive the standard in a direction that suits us.
12:31:50 <victor> Michael: what about payload formats?
12:33:52 <kajimoto> kajimoto has joined #wot
12:34:28 <victor> Daniel: it is embedded in the TD. No name for the value type, no URI.

12:36:18 <victor> Michael: An example of a whole TD should be shown for the sake of clarity.
12:37:38 <victor> Kaz: Mapping to XML Schema exists. What about mappings to e.g. C struct? Exhaustive analysis needed.
12:38:26 <mkovatsc_> q?
12:38:39 <victor> Taki: there is also CSV, flat files. How to link to existing definitions?
12:38:41 <michael> There are also some JSON template languages that have substitution features

12:40:55 <victor> IG Charter. How to proceed? One person responsible for a specific section, in charge of reviewing and merging PR.
12:42:44 <victor> important point: deliverables. Will reach out individual people for that.

12:49:22 <victor> Matthias: will make a proposal to explain that.
12:50:10 <mkovatsc_> q?
12:50:38 <victor> For the editors of the charter itself: one for each of this section introduction, scope, deliverable?

12:56:04 <victor> (after the WG is launched)
12:56:25 <victor> Matthias: agree. This should be clealry explained below in the section.

13:03:57 <victor> Matthias: links have been updated. Terminology on the figure has been updated. Remaining TODO on privacy.
13:04:53 <victor> I propose to remove it. We already have a security item. Oliver Pfaff to produce a text about "privacy by design".
13:05:19 <victor> deliverables are stable. Added WoT Test Cases
13:05:58 <kaz> q+
13:06:25 <mkovatsc_> q?
13:06:26 <victor> Test case already needed for the next PlugFest.
13:06:30 <mkovatsc_> ack kaz
13:07:34 <victor> Kaz: the IG Charter figure about relationship WG <> IG should also appear in the WG Charter.
13:08:04 <victor> WoT Test Cases should be moved to section 3.2

13:09:25 <k_nimura> q
13:09:25 <kaz> ack k
13:09:47 <victor> Kajimoto: deliverables are TD, scripting API, protocol bindings. Might induce changes in the Architecture document. What about adding this document in the WG Charter?
13:11:50 <victor> Matthias: a standard document of that kind might be needed, that reflects the evolution in the other deliverables.
13:12:19 <kaz> q+
13:12:26 <kaz> q-
13:12:30 <kaz> q+
13:13:02 <victor> Johannes: W3C procedure on that?
13:13:24 <victor> Kaz: architecture document should be a W3C recommendation, indeed.
13:14:08 <victor> (section 3.1 - Normative)

13:16:14 <kaz> q+
13:16:20 <k_nimura> related to the WoT test case, how to deal conformance ? how to prove something developed is fit to recommendation documents or interoperable each other? isn't it proper documents not like Other Deliverables?
13:17:37 <victor> Nimura: related to the WoT test case, how to deal with conformance ? Isn't it a proper document like other deliverables?
13:18:10 <mkovatsc_> q+
13:18:41 <kaz> ack k_nimura
13:18:46 <victor> Kaz: difference between conformance test (not in the scope of the W3C) and implementation check suite.
13:19:11 <mkovatsc_> ack kaz
13:19:30 <victor> Kaz: about privacy, we could simply merge security and privacy.
13:20:29 <victor> Matthias: indeed. Oliver should write in the security section.
13:23:23 <victor> Kaz: back to implementation check: W3C provides a test framework (with a test runner). Exists for HTML5
13:24:37 <mkovatsc_> q?
13:24:43 <mkovatsc_> ack mkovatsc_
13:25:23 <victor> Collaboration with the automotive group is possible regarding this.
13:27:45 <victor> Matthias: done with this topic. Again, please review.
13:28:05 <michael> I submitted a transfer layer [proposal
13:28:05 <victor> topic: next Web-conference
13:28:17 <victor> Matthias: agenda items?
