12:11:31 <kaz> ... discussed ECHONET use case
12:11:39 <kaz> ... several PRs
12:11:56 <kaz> ... possible discussion with MiniApps during TPAC
12:12:30 <kaz> mm: did you create a specific issue for that joint meeting?
12:12:34 <kaz> ml: will do
12:12:40 <kaz> q+
12:13:24 <kaz> kaz: there was some discussion on the WoT Chairs mailinglist as well

12:19:41 <kaz> ... not very active so far, but good timing to start more active collaboration
12:19:42 <kaz> q+
12:20:02 <kaz> ... one proposal is

12:21:18 <kaz> sk: possible companion standardization group between W3C and OPC UA
12:21:28 <kaz> ... just an idea at the moment, though
12:21:44 <kaz> mm: 2 thoughts
12:22:02 <kaz> ... agree need standard protocol for OPC standards
12:22:22 <kaz> ... would add this collaboration to the new Charter
12:22:36 <kaz> ... in the meantime, we can work on a separate Note
12:22:55 <kaz> q?
12:22:56 <kaz> ack m
12:23:16 <kaz> sk: what is important is what is owned by OPC UA is semantics
12:23:25 <mlagally> q+
12:23:40 <kaz> ... semantics to be standardized via RDF
12:24:04 <McCool> q+
12:24:25 <kaz> ... concrete ontologies to be defined on the OPC UA side
12:24:48 <kaz> ml: separate kinds of standards one on the W3C and another on the OPC UA
12:25:15 <kaz> ... note those two orgs have different policies
12:26:45 <kaz> s/policies/policies on IPR/
12:28:36 <McCool> q?
12:31:43 <kaz> kaz: don't think this description itself would fit with the "WoT Use Cases and Requirements" Note as a use case...
12:31:56 <kaz> -> https://w3c.github.io/wot-usecases/ WoT Use Cases and Requirements Note
12:33:01 <kaz> mm: picking an ecosytem and thinking about possible binding is useful
12:33:16 <kaz> ... but still need concrete use case description
12:33:29 <kaz> ... this is more for the Charter-level discussion

12:34:54 <kaz> -> https://github.com/w3c/wot-usecases/pull/117 PR 117 - WIP: Add liaisons
12:35:21 <kaz> mm: possibly we could think about concrete binding with OPC UA within the Binding Templates document, etc.
12:35:44 <kaz> ... but mixing it into the Use Cases and Requirements itself is confusing
12:35:46 <kaz> kaz: agree
12:36:08 <kaz> ml: liaison for Industrie 4.0, etc., itself is important
12:36:12 <kaz> mm: right
12:36:41 <kaz> ... but we need concrete description on Use Cases
12:36:55 <kaz> q?
12:37:18 <kaz> kaz: right
12:37:35 <kaz> ... we still need some concrete use case description for this purpose
12:38:48 <kaz> mm: maybe we could concentrate on the requirements part of this proposal for OPC UA binding

12:41:16 <kaz> cb: joined the WoT Use Cases a few months ago
12:41:37 <kaz> ... worked with Sebastian to generate this use case for retail purposes
12:42:00 <kaz> ... expected David's review
12:42:25 <kaz> ... initial question was how to support data exchange for retail
12:43:07 <kaz> ... ECLASS use cases varies over IoT, Engineering, ...

12:46:01 <kaz> ... there is generic description below
12:46:10 <dezell> q+ to ask whether we are thinking about products for sale, or devices, or both?
12:47:13 <kaz> [[
12:47:13 <kaz> The ECLASS Standard contains tens of thousands of product classes and unique properties. This lets you standardize procurement, storage, production, and distribution activities in and between companies - across sectors, countries and languages. Realize sales potentials and new synergies, reduce costs, and increase the efficiency of your merchandise and data management.

12:47:34 <mlagally> q?
12:48:02 <kaz> mm: comes up with useful categories
12:48:18 <kaz> ... we should think about the whole retail categories

12:49:56 <Zakim> dezell, you wanted to ask whether we are thinking about products for sale, or devices, or both?
12:50:18 <dezell> https://www.gs1.org/standards/gpc
12:50:18 <kaz> de: two other classification scheme
12:50:31 <kaz> ... a lot of products we sale
12:50:32 <dezell> https://www.nationalgrocers.org
12:50:44 <kaz> ... GS1 is one organization to be referred to
12:51:12 <kaz> ... global product classification
12:51:30 <kaz> ... with strict tree structure
12:51:47 <kaz> ... once you want some additional family, would be complicated
12:51:53 <McCool> (so something can't be both a dessert and a floor wax?)
12:52:07 <kaz> de: exactly :)
12:52:46 <kaz> mm: this use case is an inventory
12:52:55 <kaz> ... and there are many classifications
12:53:30 <kaz> ... legal requirements may differ from countries
12:54:04 <kaz> cb: not only inventory...
12:54:26 <kaz> mm: are there any processes
12:54:34 <kaz> s/sses/sses?/
12:55:04 <kaz> ... "retail inventory and equip management" would fit better for this description as a title
12:55:45 <kaz> ... ECLASS item to be mapped to some (possibly more than one) GS1 entry
12:55:45 <dezell> Note that W3C has a Dataset Exchange WG with members from Dublin Core - https://www.w3.org/2017/dxwg/wiki/Main_Page

12:56:39 <McCool> q?
12:57:35 <McCool> (sorry, I have to go... another meeting on the hour)
12:57:39 <kaz> de: dominating vocabulary discussion
12:57:56 <kaz> ml: (adds GSI and W3C DXWG to be mentioned)
12:58:14 <kaz> q+
12:58:26 <kaz> mm: general issue on ontology mapping
12:58:28 <kaz> ack de
12:59:23 <kaz> ml: we should handle mapping of classifications across description schemes
12:59:24 <kaz> q?
12:59:38 <kaz> ... Christian, could you update the description?
12:59:44 <kaz> cb: will work with Sebastian
13:02:13 <kaz> kaz: mapping of classification schemas implies data catalog as well (which the DXWG was working on)
