15:22:30 Chris: yes 15:22:47 Felix: it is not direct scope of VSSo but certainly can be attached as an extension 15:23:09 … you could organize data points by ECU 15:23:20 Chris: what triggered me was digital twin term 15:23:35 Felix: that is a trigger buzz word with different meaning to different audiences 15:24:09 … what components provide which signals, from which manufacturer etc is certainly useful ways to extend this ontology and get a bigger picture 15:25:23 Chris: we are starting down SDV project and MB is looking at DT there with emphasis for tracking ECU updates 15:25:46 Daniel: as mentioned VSSo is extensible, VSS itself allows for private branches 15:25:47 I have made the request to generate https://www.w3.org/2022/04/04-auto-minutes.html ted 15:26:36 Nick: I'm very familiar with VSS and its tree structure, how does VSSo differ in showing its relationships? 15:27:15 Felix: we use VSS to generate VSSo and immediately you can see all the static data for a vehicle based on Core portion 15:27:49 … you can see what signals (dynamic) are available in VSSo. combined with SOSA you can ask what was the temp of a given control unit at a point in time 15:28:09 … VSS defines a signal but not as recorded observations 15:28:44 Daniel: you can also link to entirely different domains 15:29:00 I have made the request to generate https://www.w3.org/2022/04/04-auto-minutes.html ted 15:29:40 Chris: this is a powerful approach 15:30:29 Felix: it requires effort but is worth it when you need detailed information about a vehicle, its components, what it is producing... 15:30:52 … you can see how supply chain issues can impact vehicle production for example 15:31:35 … ontology facilitates sharing data, it is understandable by machines readily 15:31:50 I have made the request to generate https://www.w3.org/2022/04/04-auto-minutes.html ted 15:34:16 Topic: Issues 15:34:17 https://github.com/w3c/vsso/issues 15:35:08 Daniel: please feel free to raise issues and respond to open ones, we will cover on these calls to seek resolutions 15:35:09 https://github.com/w3c/vsso/issues/22 15:35:55 https://github.com/w3c/vsso/issues/22 15:36:10 [Sub-classes vs. Instantiation of existing VSS concepts #22] 15:37:43 Daniel: we covered this during the workshop and Daniel Alvarez has some thoughts on a workaround with instantiation but his isn't available today 15:38:10 … branches are basically vehicle components, he was thinking how an observation would look like 15:39:20 … should we have some simple observation mechanism in VSSo based on SOSA? 15:40:20 Felix: that would make sense. you might also want a more basic, SOSA-less representation. possible to support both 15:40:54 s|https://github.com/w3c/vsso/issues/22|| 15:40:55 I have made the request to generate https://www.w3.org/2022/04/04-auto-minutes.html ted 15:41:45 Daniel: another idea from the workshop was OWL2 Punning 15:44:49 Ted: I'll reach out to Alan and Pierre-Antione with link to this issue, encourage their input or example 15:46:18 Felix: looking at this internally found another possible issue that I'll raise in gh. having unique URIs for the properties might have clashes if we just take property name 15:46:51 Daniel: perhaps we should table discussion until we have a next PR 15:47:20 Felix: makes sense, worth selecting issues to advance 15:47:55 Daniel: anyone here plan on attending the AMM in Leipzig besides Felix and myself?
