Meeting minutes
Minutes review
<kaz> Dec-9
McCool: any objections to approving the minutes?
… no objections, approved
Agenda
<kaz> Agenda for today
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: https://
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> wot-ngsi-ld PR 1 - Create liaison.md
McCool: merged PR #1
<Charith> I guess, this project used NGSI https://

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
