  WoT Week minutes

   [14]WoT Week F2F meeting - Day 2

     [14] https://www.w3.org/2024/11/29-wot-minutes.html


   McCool: (quickly goes through the minutes)
   … (specifically the section 9, ETSI ISG CIM for NGSI-LD)
   … Erich from Microsoft, the F2F host there, presented several
   tools
   … interesting materials for testing, etc.
   … I think we should look into that
   … the other things brought up was NGSI-LD server talking with
   devices
   … onboarding for devices
   … there are two kinds of usages: north-bound and south-bound
   … another point was discussion about possible binding
   … we have WoT Profile also
   … can think about sub-profile also
   … (shows the OPC UA liaison section also)

   [15]OPC UA section

     [15] https://www.w3.org/2024/11/29-wot-minutes.html#97e7


   McCool: have to ask Erich about the detail
   … that's the minutes from the WoT F2F in Munich

   Juanjo: need to look into what you mentioned, but not sure
   about their approach

   McCool: agree
   … let's raise an issue for further discussion

   Juanjo: not pretty sure about their approach
   … would hear from Martin, etc.
   … but FIWARE handles things based on NGSI-LD
   … WoT Thing Model is agnostic with the protocol
   … how things could be considered as instances of the model
   … which could be accessed from NGSI-LD
   … there could be a Thing Model which can be accessed from
   NGSI-LD
   … then we can on one side from NGSI-LD by FIWARE/ETSI and WoT
   side describing the entity classes
   … NGSI-LD can be used to interoperate with the things

   McCool: there are two things here

   Juanjo: the definition of "Things" focused on not necessarily
   "devices"
   … maybe physical ones or might be virtual ones

   McCool: that's a fair point
   … we have linked data, and there are different kind of "Things"
   … my personal opinion is that you can do it from the scratch

   Juanjo: remember how this discussion started
   … standard API for digital twins
   … physical or digital devices
   … common understanding with the WoT Thing Model for the
   ingredients for the entities
   … then NGSI-LD interact with the digital twins

   McCool: we do have model for Thing Description
   … real question is mapping ontology, etc.

   <McCool> ege: [16]https://youtu.be/

     [16] https://youtu.be/dUb_oP2kCBQ?si=o6W7TOnfvyca5hjm


   Ege: presentation by a company about a use case from eclipse
   ditto

   [17]youtube video

     [17] https://youtu.be/dUb_oP2kCBQ?si=o6W7TOnfvyca5hjm


   Ege: the person was at the Plugfest
   … this is already possible for TD, I think

   McCool: even though there is no blocker, would see what can be
   done easier
   … need to dig it up
   … would talk with Erich about the detail a bit more

   Juanjo: know about the work by Microsoft
   … there is an initiative about smart datamodel

   <McCool> [18]https://smartdatamodels.org/


     [18] https://smartdatamodels.org/


   Juanjo: for a given model for digital twins
   … (Juanjo gives some description about the Smart Data Models)
   … don't know which actual model to be picked up...
   … corresponding similar digital twin mechanism

   McCool: (shows "dataModel.Building")

   Juanjo: there is not description language for
   dataModel.Building. right?
   … if WoT Thing Description could be assigned to that, we might
   be able to use that

   Kaz: let's not dive int the detail about that
   … but let's talk about the logistics and planning doc for today

   McCool: yeah

  Logistics

   McCool: Kaz, you can make the meeting on Jan 6. right?

   Kaz: yes

   McCool: so the next meeting after this meeting will be Jan 6

   Martin: public holiday in Germany

   McCool: we can shift the meeting by one week

   Kaz: note that this is a bi-weekly meeting

   McCool: may impact the WoT CG meetings then

   Ege: don't worry

   McCool: next meeting on Jan 13 and every two weeks after that

   Martin: might be better to have the meeting every week for a
   while

   McCool: ok
   … Jan 13 and then every week until mid-Feb after that

  Charter

   McCool: would like to update the Charter (=planning doc)

   [19]PR 1209 - Activate Liaison for ETSI ISG CIM for NGSI-LD

     [19] https://github.com/w3c/wot/pull/1209


   McCool: this PR is putting the proposal to the actual area, but
   it's too early
   … so would close this PR itself without merging
   … and then create a new PR for further updates

   [20](new PR) PR 1222 - Update ngsi-ld.md

     [20] https://github.com/w3c/wot/pull/1222


   [21]rendered MD

     [21] https://github.com/w3c/wot/blob/bef536cb472af78dd8a34bca5f2bcfb8377b2bbb/proposals/liaisons/ngsi-ld.md


   McCool: (goes through the changes)
   … need some more detail here
   … we can mention some more concrete documents like possible
   bindings
   … or we can define concrete deliverables externally

   Juanjo: we didn't have time so far, but would make some
   requests

   Martin: not sure about how to work on that

   <McCool> [22]w3c/wot#1222

     [22] https://github.com/w3c/wot/pull/1222


   Kaz: probably we should use the dedicated wot-ngsi-ld repo for
   further discussion
   … to let ETSI guys give direct contributions easier

   [23]wot-ngsi-ld repo

     [23] https://github.com/w3c/wot-ngsi-ld


   Kaz: can add you all from ETSI to the collaborators for the
   repo (like we did for the W3C server)
   … sorry but we need to do that for GitHub again since it's a
   different system from the genuine W3C server

   McCool: (shows how to make contributions to the GitHub
   resources via Pullrequests (PRs))
   … you can also create a dedicated branch for your edit

   <McCool> [24]w3c/wot-ngsi-ld#1

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


   McCool: (creates an initial PR as above)
   … (also adds some more topics like the Smart Data Models)

   Kaz: please let me know about your GitHub account so that I can
   add you all to the GitHub collaborator Team for the wot-ngsi-ld
   repo
   … also for Frederic, please let me know about your email
   address, and I can help you create a W3C account also
