Review feedback

   Sebastian: TAG had review of WoT architecture

   McCool: privacy protection has to come from higher level than
   TD, so it's hard to evaluate the privacy implications

   <inserted> [18]July-17 TAG agenda

     [18] https://github.com/w3ctag/meetings/blob/gh-pages/2019/telcons/07-17-agenda.md

   <inserted> [19]PING comment

     [19] https://github.com/w3c/wot-thing-description/issues/794

   McCool: we don't have means to protect privacy
   ... PING is interested to work on the directory API with WoT

   Lagally: we didn't include any mandatory API at this point
   ... an API may not be specified in this charter period

   McCool: emphasize TD is just a data format
   ... but we should commit to working with PING on any future
   development, e.g. an API spec

   Koster: API means a resource type definition; we need an end to
   end system to tell privacy implications

   McCool: the spec says privacy should be controlled by the
   actions defined
   ... there is also a possible Discovery API, and others as well
   (management API etc)
   ... See TD issue #794

   <kaz> [20]TD issue 794 (PING comment)

     [20] https://github.com/w3c/wot-thing-description/issues/794

   McCool: security is in TD endpoints, we can't limit people from
   making devices that expose private information
   ... we don't make APIs for devices
   ... we should remain descriptive
   ... HTML analogy - privacy is not granted by HTML alone

   Taki: In the joint PING call, we received a harsh comment for
   not describing protecting privacy for TD model. Therefore, it
   would be wise to focus our comment on the future commitment,
   rather than making an excuse at this point.

   Sebastian: discussed with security experts in Siemens; this is
   a typical privacy discussion which will never find solution,
   concerns will appear anyway

   McCool: right, it's a best effort thing, we have risk
   assessment and mitigation described
   ... this is an important topic for the next charter
   ... moving on with the agenda

   Kaz: if they can provide several concrete points for important
   privacy issues, probably we need to incorporate those issues
   and possibly we need to publish an updated Candidate Rec.
   However, we should mark the issues as "v.next" if they're not
   fatal for the current version.
   ... note that we need to wrap up everything during the
   extension period (6 months)

TPAC / F2F planning

   McCool: we should defer this to the plugfest call
   ... topics need to be filled in

   <inserted> [21]f2f wiki

   McCool: (shows the changes)


     [25] https://github.com/w3c/wot/pull/838/files

   McCool: industry vertical potion
   ... getting Michael Lagally's input

   Lagally: suggesting reword
   ... "including PlugFests for specific vertical industries"
   ... to
   ... "including interoperability events for specific vertical

   Sebastian: what about "Hackathon" instead of PlugFest?

   McCool: "organize and run interoperability testing events,
   including events for specific vertical industries,"?
   ... implementations to be collected
   ... we don't have official conformance testing
   ... on the other hand, we have online testing events as well
   ... plugfest is for testing interoperability
   ... (saves the updated text)
   ... group agrees to my suggested change above
   ... and the next comment from Lagally
   ... "would change the order a bit and put SDOs and industry
   alliances higher in the rank"

   Lagally: also we should have community guys as well

   McCool: how about SDOs first?
   ... then industry alliances
   ... and then providers
   ... SDOs are grouped with industry alliances
   ... alliances are also grouped with providers

   Lagally: ok

   McCool: next Wendy's comment

   Sebastian: deadline?

   Kaz: there is a specific procedure
   ... W3M review first (we're here) and then AC review next
   ... AC review takes one month

   Charter document has been updated accordingly.]

Profile discussion

   McCool: main issue is timing
   ... when to add it
   ... reopen the CR spec and add it now?
   ... or defer to v.next?

   Lagally: I'm not suggesting we reopen the spec now
   ... rather would propose to create a separate document

   Sebastian: would be good to have some concrete proposal based
   on slides

   Lagally: we already had discussion but can provide some

   [29]Profile discussion last week

   Lagally: we can use the half of the Architecture call tomorrow
   for the profile discussion

   Sebastian: I'll be travelling tomorrow

   McCool: would be better to discuss it during the TD call Friday

   Lagally: ok
