   <kaz> (Kaz notes that we still need to clarify the actual dates
   for the WoT meetings, which consist of OpenDay including
   liaison SDOs, Breakout discussion and WoT group discussion,
   during TPAC.)

   Christine: Liaisons wrt/ geo-fencing using standards

   Spatial web working group

   Christine: New IEEE P2874 Spatial Web Protocol Working Group
   has quite mature ideas, so let's exchange with others having
   mature ideas

   IEEE P2874

   McCool: Add P2874 to liaisons list, also OGC

   <kaz> (Kaz mentions some idea about possible OpenDay topics as
   follows:

   <kaz> 

   <kaz> * Current status of IoT services

   <kaz> ** Industrial gateways (Bosch, Siemens, Fujitsu)

   <kaz> ** Automotive (Volkswagen, Audi, BMW, Daimler)

   <kaz> * Existing standards and deployed ecosystems (based on
   our liaisons)

   <kaz> ** Platform Industry 4.0

   <kaz> ** OPC UA

   <kaz> ** ECHONET

   <kaz> ** ITU-T

   <kaz> ** ECLASS

   <kaz> ** ISO TC 184/SC4

   <kaz> * Future need for for Web-based IoT

   <kaz> ** Home automation scenarios

   <kaz> ** Smart Cities

   <kaz> ** Retail

   <kaz> ** Healthcare

   [15]PR 217 - Add Well-Known URI and Service Name in "IANA
   Considerations" section

     [15] https://github.com/w3c/wot-discovery/pull/217

   Toumura: Just editorial change

   McCool: Concern about potentially long URIs

   McCool: "wot-thing-description" too long?

   "wot-td" instead?

   McCool: Fix typo and merge

    PR 218

   [16]PR 218 - HTTP HEAD method to request the content length

     [16] https://github.com/w3c/wot-discovery/pull/218

   McCool: Profiles aims to forbid head methods, but should
   directories follow a profiles?

   Farshid: Does not add any feature to TDD.

   McCool: Supports pagination of large TDs

   McCool: SHOULD or MUST feature?

   Farshid: Easy to implement.

   McCool: Will be changed to MUST.

   HEAD possible on all endpoints (listing, search, etc.)

   Yet another possbility for constrained devices to handle large
   TDs, fragments, etc.

    PR 219

   [17]PR 219 - HTTP HEAD method to request the content length
   (self-description)

     [17] https://github.com/w3c/wot-discovery/pull/219

   McCool: https challenging for constrained devices, so http (not
