   McCool: some minors only, will publish

   no objections; approved

  planning

   Kaz: no update on WD publication

   McCool: we need to aim for June 1st for a stable draft
   … should we extend the call to 2 hours for the next three
   weeks?

  PR 168

   [15]PR 168 - Add alternative payload format

     [15] https://github.com/w3c/wot-discovery/pull/168

  PR 166

   [16]PR 166 - Typos against main

     [16] https://github.com/w3c/wot-discovery/pull/166

   merged

  PR 162

   [17]PR 162 - Expiry date for registered TDs

     [17] https://github.com/w3c/wot-discovery/pull/162

   [18]Preview - 6.2.1.1 Registration Information

     [18] https://pr-preview.s3.amazonaws.com/farshidtz/wot-discovery/pull/162.html#exploration-directory-registration-info

   McCool: what do you mean by "read-only" here?
   … which is the directory?
   … someone reading the TD?

   Farshid: yeah

   McCool: but it's still confusing to have two roles here
   … (regarding 'expieres') also how to distinguish the expiration
   timing?
   … would be clearer to simply refer to the ttl

   Farshid: ok
   … will update 'expires' and 'ttl'

   McCool: the time is based on when the data is registered
   … (going through the "Files changed")

   [19]PR 162 - Files changed

     [19] https://github.com/w3c/wot-discovery/pull/162/files

   McCool: the biggest problem is about 'expires' and 'ttl'
   (relative time vs absolute time)

   Farshid: can generate another PR to fix those points

   McCool: let's merge this PR 162 itself and will create a new
   issue to address those points
   … then fix the issue with a new PR

   [20]McCool's comments for PR 162

     [20] https://github.com/w3c/wot-discovery/pull/162#discussion_r629434051

   (issue 162 merged)

   [21]new issue 171 to address the remaining problems

     [21] https://github.com/w3c/wot-discovery/issues/171

  the other PRs

   McCool: how to deal with the other PRs?
   … would have Ben to discuss them

   (PR 158, 159 and 160 by Ben)

    PR 160

   [22]PR 160 - Rename actions to match properties and events

     [22] https://github.com/w3c/wot-discovery/pull/160

   McCool: (skims PR 158)

   Farshid: should we have a separate PR for converting Thing to
   TD?

   McCool: why don't we comment here?
   … (adds a comment to PR 160)
   … we generally agree that the new names are a useful
   improvement
   … but disagree on the merger of PUT/PATCH (especially if
   they're hard to distinguish in the Scripting API, or make it
   harder to distinguish the functionality in other protocols/make
   the API more HTTP specific)
   … so if we had a PR that *JUST* did the name changes, we could
   merge it

   [23]McCool's comment to PR 160

     [23] https://github.com/w3c/wot-discovery/pull/160#issuecomment-836816733

     [26] https://github.com/w3c/wot-discovery/pull/159#issuecomment-836822282

   McCool: Farshid, can you add your comments as well?

   Farshid: ok

   McCool: can we merge this PR 159?
   … (adds another comment that his PR 159 is based on an old
   version spec)

   [27]McCool's new comment

     [27] https://github.com/w3c/wot-discovery/pull/159#issuecomment-836823973

   McCool: let's check with Ben then

  Issue 169

   [28]Issue 169 - EnrichedThing as a class?

     [28] https://github.com/w3c/wot-discovery/issues/169

   McCool: how does this relate to Thing Model?

   ac: please see the example below

   McCool: so multiple inheritance here?

   ac: yes

   ac: if this addition brings confusion, we can skip this

   McCool: (adds some comments)
   … (e.g., in some cases, Thing needs to provide information that
   is part of the enriched data namespace (not core TD))

   [29]McCool's comments

     [29] https://github.com/w3c/wot-discovery/issues/169#issuecomment-836836547

   Farshid: seems there is some confusion

   McCool: (adds some more comments)
   … having an "@type" for "EnrichedThing" would be nice

   [30]McCool's new comments

     [30] https://github.com/w3c/wot-discovery/issues/169#issuecomment-836852392

   [31]McCool's additional comment

     [31] https://github.com/w3c/wot-discovery/issues/169#issuecomment-836855613

   Kaz: a basic question here
   … if a Thing can accept multiple inputs, e.g., one from Link
   and another from Directory at once, how the Thing can tell
   those inputs are compatible and generate the consolidated TD
   (or EnrichedThing)?
   … we need to clarify the algorithm based on some concrete use
   case scenario
   … we need to have some specific/limited set of namespaces to be
   included here. right?
   … maybe not for the WoT Directory itself, but we should have
   how to manage multiple namespaces to be consolidated for a TD

   McCool: maybe you could add comments to this Issue 169 or
   create a new issue about that point?

   Kaz: yeah

   (some more discussions)

   Kaz: how can the Thing tell which Discovery service to be
   referred to?

   McCool: we currently use "w3c.github.io" URL but that is not
   our intention for the actual service

   [32]related issue 148

     [32] https://github.com/w3c/wot-discovery/issues/148

   McCool: we should use a sub-URL under td, e.g., [33]https://
   www.w3.org/ns/td/directory
   … or continue to use GitHub for now, and dd an ednote
   … or assume a given URL, use it in all examples

     [33] https://www.w3.org/ns/td/directory

   Kaz: when we created ns/td namespace, we didn't really predict
   we would have some more namespaces for WoT purposes
   … probably we should list all our necessarily namespaces for
   WoT purposes and then think about how to call them

  AOB

   McCool: need to talk with Ben as well
