  Minutes review

   <kaz> [8]Dec-9

   McCool: any objections to approving the minutes?
   … no objections, approved

  Agenda

   <kaz> [9]Agenda for today

      [9] https://www.w3.org/WoT/IG/wiki/WoT-NGSI-LD#January_13,_2025


   McCool: we are having meetings weekly to get started
   … asking people to add documents to the github repository
   … would like to clean up the repo as part of the agenda
   … we can gather resources
   … there is a PR to merge the liaison charter document into the
   reop

   Martin: we need to decide how to proceed and develop some
   simple and concrete initial examples

   McCool: I think it will be helpful
   … we could work toward a use case

   Kaz: agree with mccool, thank you Martin
   … maybe we could use the W3C WoT's use case template

   Rigo: discussing use cases would be a really nice idea
   … how does the application layer of WoT relate to NGSI-LD?

   <rigo> especially for robotics, the StandICT landscape analysis
   for digital twins just came out: [10]https://www.standict.eu/

   landscape-analysis-report/landscape-robotics-standards

     [10] https://www.standict.eu/landscape-analysis-report/landscape-robotics-standards


   McCool: can we add Martin's initial presentation to the repo?

   Martin: will go look for it

   McCool: if you think of something to add, please make a PR to
   add it

    Liaison document

   McCool: the only update is changing language from binding
   specific to a more general "document"

   Martin: we could add the NGSI-LD spec but it's large

   <kaz> [11]wot-ngsi-ld PR 1 - Create liaison.md

     [11] https://github.com/w3c/wot-ngsi-ld/pull/1


   McCool: merged PR #1

   <Charith> I guess, this project used NGSI [12]https://
   cordis.europa.eu/project/id/732240/reporting (perhaps as a
   associated project or usecase, if helpful)

    Examples of use cases

   McCool: makes sense logistically to put them in the repo
   … creates "examples" directory in the repo

   McCool: we can also link to external documents

   McCool: it would be useful to brainstorm some topics
   … functional clustering of resources?

   Rigo: it describes how to cluster things in a complex system
   … for WoT there is a consistent interface, then how do you
   cluster for example hundreds of sensors
   … it's a simplification of workflows

   McCool: in a WoT TD, there can be multiple devices and separate
   functions
   … TDs are linked data

   McCool: are there any other thoughts on categories of examples

   Martin: let's check the use case in the primer for a starting
   place

   McCool: this could become a to-do action item

   Kaz: agree, we could start with a brainstorm around use cases
   possibly including smart city use cases rather than strict
   description according to the WoT template

   McCool: at a previous meeting, we discussed using WoT to model
   digital twins

   McCool: another use case is using TD to onboard devices
   … another case is describing a northbound interface for digital
   twins

   Rigo: there is a landscape analyzer as a negative example, it
   is only a list of specifications and doesn't explain how the
   standards relate to another

   Martin: agree, we don't want a list and would rather keep
   things small and compact

   McCool: what are the subcategories of digital twin, i.e.
   location, device shadow, etc

   Rigo: we should clearly define our boundaries
   … from a legal perspective
   … there is no upper bound on what can be done

   McCool: safety and privacy are not unique to smart cities
   … not a data model problem in general
   … not sure also what WoT brings to the table

   Kaz: part of the brainstorming is noting which topics fall
   under WoT/NGSI-LD

   Rigo: an example is a sensor that has built-in security logic
   that can interoperate with a smart data management system
   … for example, a block in the TD containing this metadata can
   allow smarter data management by pushing it down to a lower
   level

   Martin: what is the functional part of this interface?

   McCool: it reminds me of functional items for safety we
   discussed in WoT some time back

   McCool: there are policies and rules that have metadata support

   Rigo: this is precisely what I am talking about

   Koster: another item is what is the scope of things that can be
   modeled using TD that may not have digital interfaces

   McCool: OK, I will commit this now, please create separate .md
   files for things that are added

   McCool: that is all I had for the agenda
   … next meeting is January 20th

   McCool: are there any other items for the agenda today?
   … ideally we will have some PRs to review next week
   … is there any other discussion or business for today?
   … OK, let's adjourn for today
