   <kaz> [30]PR 51

     [30] https://github.com/w3c/wot-profile/pull/51

   overview of the PRs

     [31] https://github.com/w3c/wot-profile/pulls

   its about canonical json representation

   <kaz> [32]5.3.1 Canonical TD representation

     [32] https://pr-preview.s3.amazonaws.com/w3c/wot-profile/pull/51.html#canonical-td-representations

   Sebastian: maybe we should replace "string" with "value"

   Lagally: that is the reason why we need canonical
   representation that organize the order

   McCool: This was also a topic in the joint JSON-LD call.
   Important topic
   ... its not a easy topic.

   Lagally: should be synchronized with the JSON-LD group
   ... what should we do with it right now?

   McCool: question if we want to have this in the profile spec

   <inserted> scribenick: kaz

   Sebastian: this is kind of related to TD
   ... general topic to be clarified
   ... so would postpone the discussion
   ... not good to be mentioned only here within the WoT Profile
   ... to be discussed for the Thing Description as well

   Lagally: ok
   ... let's keep this open then

   [33]PR 52

     [33] https://github.com/w3c/wot-profile/pull/52


     [34] https://pr-preview.s3.amazonaws.com/w3c/wot-profile/52/935d53b...5804a88.html#abstract

   Lagally: (goes through the diff preview)

   McCool: a couple of comments on possible "other" profiles
   ... name of the profile as ID
   ... saying "describe" is too strong here

   Lagally: what would be good then?

   McCool: e.g., "identify"

   Lagally: so far there is only one profile here
   ... also we don't expect the FPWD of the WoT Profile defines

   McCool: we need to decide if this is a single thing
   ... or just due to some constraint

   Sebastian: it's concerning the first sentence
   ... problem with "Core" Profile
   ... saying "The WoT Profile Specification defines a WoT Core
   Profile, which enables out of the box interoperability among
   things and devices."

   McCool: would be simpler to say "which defines..."

   Lagally: ok

   [35]5.2 Protocol Binding

     [35] https://pr-preview.s3.amazonaws.com/w3c/wot-profile/52/935d53b...5804a88.html#protocol-binding

   Lagally: (goes through the Note there)

   <inserted> "The HTTP protocol binding is not meant to be

   Lagally: we don't mandate HTTP

   McCool: but mandated by the user

   Lagally: can update the first sentence of the Abstract

   Sebastian: notification protocols

   Lagally: if we mention subprotocols here, would it suffice?
   ... can easily add changes

   Sebastian: ok

   Kaz: wondering about the concrete text for the 2nd bullet point
   from the Abstract

   McCool: ok with the current text of the bullet points *for the

   Kaz: ok

   Lagally: (adds updates accordingly)

   McCool: (proposes to say "specific subprotocols" for

   Lagally: done
   ... but we still have 3 more PRs

   Sebastian: PR 48 can be closed

   [36]PR 48

     [36] https://github.com/w3c/wot-profile/pull/48

   Lagally: ok
   ... (adds a comment and close it)
   ... and then the final one

   [37]PR 50

     [37] https://github.com/w3c/wot-profile/pull/50

   Lagally: we don't mandate anything for other profiles

   McCool: that's fine

   Lagally: so if we apply the remaining two points, we can merge
   this PR
   ... would merge the PR itself first, and then apply the two
   remaining comments
   ... (merges PR 50 itself)
   ... (and then add edits for the remaining two comments)
   ... now we have an updated draft for publication :)
   ... but got another respec issue :(

   <mlagally_> proposal: publish the current contents of the
   master branch on [38]https://github.com/w3c/wot-profile as FPWD

Shortname for 1.1 version publication

   Kaz: regarding the shortname URL, the suggestion of Ralph and
   PLH was using "11" for ver 1.1
   ... so "wot-architecture11"
   ... these days that notation is the most common one

   <sebastian> what about wot-architecture/v1.1
