   McCool: Is everyone available on the 26th at 2 hours earlier
   than this slot?

   (no objections)

   McCool: August 26th, 8AM US Eastern

  Liaison information

   Kaz: Still waiting for response
   … we should ask about status

   Franck: The work is being moved to a new TC
   … Next we will create a proposal

   McCool: what is the priority in your group?

   Franck: there is a round table today where we will discuss new
   projects

   McCool: So there is an intent to go forward, and you are
   organizing things?

   Franck: Yes

   McCool: We are working on our new WoT charter, which is both a
   distraction and an opportunity to accommodate new activities

   Kaz: WoT Working groups are chartered for 2 years, and our
   current charter ends in September. We want to include the
   NGSI-LD collaboration in the new charter

   McCool: We need to have a discussion in the larger group about
   the new charter

   Juanjo: Who will take over the NGSI-LD advocacy?

   Koster: I will handle that

  Plugfest

   McCool: The plugfest is taking place in November at the annual
   W3C TAPC conference in Kobe, Japan
   … We plan to present the outcome of the Plugfest at a
   conference session
   … We are planning to offer remote connectivity for the Plugfest
   and there is a remote participation option for TPAC

   Juanjo: We have a presentation

   McCool: We could probably invite you as a guest to present in
   the context of the liaison and our new charter

   Kaz: We have a liaison session where we could have the
   discussion

   McCool: Can we invite guests?

   Kaz: We can invite guests for the Breakout session, so probably
   can work something out

   <kaz> (FYI, the WoT F2F meeting will be held on 13-14 November,
   and the breakout sessions will be held on 12 November)

   McCool: Also the registration for remote participation is very
   cheap

   Franck: What is the expected outcome of the Plugfest?

   McCool: Interoperability between WoT implementations and
   exploring new features

   <kaz> [11]GitHub for the previous Plugfest in Munich in
   November 2024

     [11] https://github.com/w3c/wot-testing/tree/main/events/2024.11.Munich


   Kaz: We usually create a GitHub page to organize (link in the
   IRC)
   … We can test some candidate devices

   McCool: the testing is focused on Thing Description document
   itself but we could focus more on device behavior conforming to
   expectations set by the TD

   Juanjo: We would like to explore how to connect devices to
   FIWARE using Thing Description as one scenario
   … There is another scenario we are more interested in is using
   Thing Model as a language to create entities in the system
   using Thing Description
   … We may try to bring a Proof of Concept
   … We need to extend NGSI-LD to support actions
   … At least we will support Properties and Events

   McCool: It only needs to do the basic operations to validate
   the TDs

   <jhierro> The second scenario we are more interested it means
   using the Things Model language (abstract of Things Description
   Language) to describe Things for which NGSI-LD can be used to
   interface with.

   McCool: You could use the Thingweb Playground and TD validation
   tools

   Kaz: What would you like to prioritize to work on by the time
   of the Plugfest? Clarification on possible scenarios and use
   cases for Action binding? or actual implementation using your
   PoC for Plugfest?

   Juanjo: The two parts are connected. We want to develop the use
   of ThIngModel as a language and create a Proof of Concept to
   test
   … In parallel we will work on the NGSI-LD extension for Actions

   McCool: There are 2 use cases; northbound and southbound, each
   with a set of issues
   … one is exporting TDs to validate, exposing NGSI-LD resources
   through TD, and the other is importing, consuming external
   resources as NGSI-LD through TD
   … The PoC can be limited to reading and writing Properties
   … You may encounter issues around dynamically created resources

   Juanjo: It may not be an existing NGSI-LD system but a new
   design that can be created using ThingModel as the language

   <jhierro> WoT Things Model language as the language for
   describing Thing classes.

   <jhierro> Instances of such Thing classes would be accessible
   through NGSI-LD.

   McCool: ThingModel can be used to dynamically create new thing
   descriptions

   McCool: We should consider using the WoT use case process on
   Github issues

   ( sharing Github screen and Use Case template )

   McCool: It might make sense as we go forward to create some use
   cases and user stories

   Kaz: The core question is how to model Actions on the TD side
   also, possibly using ThingModel as a template for Actions

   McCool: Can we invite NGSI-LD to the Plugfest call on the 6th?

   Koster: will do that

   McCool: AOB?

   McCool: will create a calendar entry foe August 26

   McCool: Adjourned
