   McCool did some work on Use Case document

   we had a longer break, we need to agree on how to move forward

   We need to check regarding the organizational change on ETSI
   side from ISG CIM to TC DATA

   kaz It depends on the ETSI side (and we're waiting for the
   response from Franck about this)

   Minutes are approved

  Logistics

   Sebastian can join once a month

   McCool will stop activites by end of August

   Michael Koster could continue activities

   Possibility to handle this liaison discussion during the WoT
   main call

   we have been discussing use cases, these need to be made more
   concrete

   we need detailed attempts to use it together

   we need to resume from where we left off in April

   Kaz: We usually hold Use Cases discussion as a resource of spec
   generation, and maybe the goal of this liaison discussion is a
   bit different from our ordinary WoT Use Cases discussion. So
   probably it would make sense to think about how to deal with
   this liaison discussion a bit more.

   McCool: we need a process capturing external requirements, in
   the past requirements weren't actionable
   … not everybody in W3C is convinced about the process
   … externally driven, more top-down approach is needed
   … it needs to be concrete - try to do it and see what is
   missing

   <kaz> [7]Onboarding Use Case on wot-ngsi-ld repo

      [7] https://github.com/w3c/wot-ngsi-ld/blob/main/examples/onboarding.md


   McCool: Onboarding of IoT devices to NGSI-LD is core use case
   for WoT
   … What features are missing that an NGSI-LD system really needs
   … we have some options here
   … The other use case was to access Entity through WoT described
   interface
   … this may require more features in WoT
   … NGSI-LD side should try some things out
   … Next plugfest will be at TPAC? open to non-members?

   Kaz: we could invite non-Member stakeholders if needed

   McCool: TPAC will be in Japan, thus attending in person may be
   difficult, and then do it remotely
   … this needs preparation and bring something (almost) working

   Kaz: personally okay to start with onboarding topic and invite
   NGSI-LD people. Wondering whether this would be of interest to
   ETSI side, because Marting gave another general use case on "TD
   for NGSI-LD Entity".

   Martin: More interested in the other use case. Not sure what
   others think.

   McCool: may start with some simple part, e.g. reading and
   writing attributes only
   … Plugfest planning has not started yet

   <kaz> kaz: scribenick: kazgoing now

   McCool: Let's do this meeting once a month --> two meetings
   more for McCool

   McCool: Plugfest activities start mainly in fall

   kaz; Actually, Plugfest preparation discussion has already
   started, and a dedicated Wikipage has been created for Plugfest

   McCool: so we may have Plugfest meetings earlier

   McCool: we should find out what your plans are

   McCool: create some minimum viable use case and implement that

   Martin: have one more meeting in July with more people from
   ETSI side involved

   Martin: Moving to other set of Plugfest calls - it is not so
   clear what that means

   McCool: Martin, talk to the other ETSI people, not next week
   due to TC DATA meeting, but e..g. the week after

   Martin: Ok, I will organize on our side

   McCool: I'll book the date, but if another time / date is
   better, let me know

   Martin: Ok

   Kaz: Just to make sure, what McCool is suggesting is inline
   with ETSI's expectation. It's that we'd like to start with a
   smaller and simpler part of the expectation.

   McCool: plan from easiest to hardest

   McCool: can you put the Plugfest link in?

   <kaz> [8]WoT Plugfest during TPAC 2025

      [8] https://www.w3.org/WoT/IG/wiki/Wiki_for_TPAC_2025_planning#WoT_Plugfest_during_TPAC_2025_(Hybrid)

   McCool: not sure you can edit the wiki - if you cannot, send an
   e-mail to kaz

   McCool: Plugtest will be during TPAC in Kobe, Japan 10-14
   November

   McCool: Link to testing github, may have relevant test cases,
   e.g. TDs

   McCool: can you read these in and turn them into NGSI-LD
   entities

   <kaz> [9]Example TDs from the Testing event in 2022

   McCool: Then we need to update Liaison info

   Kaz: We are waiting for Franck, etc., about the contact person
   for the liaison.

   <kaz> [11]W3C Liaison entry for ETSI (Kaz is the contact from
   the W3C side)

   McCool: The testing event in 2024 has some more advanced
   features, including thing models --> have a look

   Martin: Ok, I'll talk to the others from ETSI
