Meeting minutes
Logistics
McCool: would like to talk about the next steps
… as we discussed last time, Plugfest is a possibility
… also use cases
… your group could give input to the WoT use cases discussion
Minutes
minutes of last meeting to be reviewed
August 31st, Michael McCool leaves Intel and also participation in WoT
Michael Koster, as captured in last meeting minutes, will take over
Discussing now about plugfest in November
Joining remotely would require paying some participation fee but should be cheap
Minutes of last meeting approved
Next Steps
TPAC 2025
<kaz> TPAC 2025 venue
<kaz> TPAC 2025 schedule
<kaz> TPAC 2025 registration
Other possible options
other option is to continue meeting series
… Sebastian can only join once a month, not once a week
other option is F2F meetings. Easiest place in Munich
meeting options include Munich, Sophia Antipolis, Berlin
… seen a lot of discussion by various manufacturers. There are gaps about reasoning on this information, not only what the devices do
… more engagement about industrial application is WoT. While higher level modeling would go rather SC IG
It has to be checked whether Repo ownership and so are resources where Michael Koster has right privileges on
Discussion about original goals of the liason
Rigo and Juanjo remind goal was to avoid fragmentations and try to come with a unique solution combining the best of WoT and NGSI-LD results
Purpose of the NGSI-LD liaison and Smart Cities IG as an option
Purpose of liaison?
*** Capture opportunities for standards for digital twins...
*** Explore aligning the visions of NSGI-LD and WoT...
*** Avoid fragmentation...
*** Avoid unnecessary transformation,
*** Capture ambient semantics
*** Understand both without a large burden
*** Not sufficient that it's useful, needs to be carried by institutions
Kaz: reminds of the W3C Smart Cities Workshop and the Web-based Digital Twins for Smart Cities Interest Group. had discussion about possible Web-based framework and ontologies for smart city purposes
… with JTC1 guys, etc.
… I'd suggest you bring your pain points, best practices and ideas to that group
… if you're still interested PoC implementations, you could join the WoT Plugfest during TPAC as well
… note that I'm not suggesting we move this discussion to ISO. actually, NGSI-LD by ETSI/FIWAARE is already one of the liaison targets for the Smart Cities IG. ISO, IEC, JTC1, etc., are also part of its liaison targets.
McCool: we are mostly talking bottom up, but also large scale top down, in smart cities information modelling. But this group is mostly on industrial modelling
… NGSI_LD was interesting because of the FIWARE connection. This gives you more access
Juanjo: FIWARE community perspective is also to work for other domains. Question about introducing actions is also cross domain
… it is also an important industry
McCool: to engage with WoT, driven by Siemens, is really going into industrial space.
McCool mentions that continuing discussion within W3C Smart Cities Interest Group would be nice but one issue is that some of the relevant people within WoT to engage are more focused in industry (factories, etc) matter
Juanjo: who is active in SC IG and at the same time in the WoT?
Kaz: Michael Koster is the chair of the Smart cities IG (SC IG)
… the group is a liaison center for digital twins and smart cities within W3C
McCool: reaching out to groups that do AI. Lot of technical activities. Big interest in knowledge graphs for reasoning on conformance and security
… device, wanna talk to it and that's it. If digital twins goes way beyond the scope of WoT. Have discussions happening in a group that is more higher level
Juanjo: we may imagine that the IG could be extended beyond smart cities
McCool: focus, digital twins, wanted to narrow the focus to avoid boiling the ocean. Was done deliberately to narrow attention. But people need to consider discussing issues across domains.
Kaz: group holds monthly meetings, next meeting will be subject to doodle poll.
ACTION: Kaz will send doodle poll for SC IG to this Group as well
McCool: suggested to pre-advertise this topic of wot & ngsi-ld to the IG
Juanjo: we have worked in support of actions in NGSI-LD, make it compatible. Were ready to present some of the results. We are making good progress on that front.
… maybe we can bring that progress to SC IG
McCool: where is the right venue for that discussion
… feedback for design, drill down use cases. Would good to warn SC IG to get good feedback
… in general, the other topics, should be rather a seminar with a focus on one topic, not just an open Workshop
Kaz: what the SC IG has been doing is inviting the related SDO people and ask them about pain points, and discuss what Web standards could do for them.
McCool: not having regular meetings like this, but concentrated seminars with a fixed roadmap
McCool: next meeting should be organized by M.Koster. Kaz should inform him
… invite people here to SC IG for them to see if it makes sense.
Kaz: SC IG will publish Agenda in advance. We can invite you any time
McCool: question: should we merge ngsi-ld mailing list into other things. Probably good idea to cross things
Kaz: we don't need to do so. I can simply invite the NGSI-LD guys to the SC IG. I'll talk with Koster as the Chair of the SC IG about that.
