Are they still in scope? <kerry> +q <jtandy> [and that the examples in those vocabs are provided in line] SimonCox: no reason to interfere with that part aharth: if you get imprecise with time, how do you do the comparison operators SimonCox: comparison operator result will be undefined in certain circumstances <kerry> +1 to simon kerry: there is a strong user base of time, thus we would have to have a very strong reason to change or remove current components <ChrisLittle> +1 to Simon SimonCox: fully aware of that and have this as a principle SSN: progress report and IoT-lite [1] [1] http://www.w3.org/ ahaller2: regarding webprotege and upload of ssn parts to webprotege, I received the namespace only 3 days ago, and did not have time yet to upload it. will do until next meeting <kerry> [13]https://www.w3.org/Submission/2015/SUBM-iot-lite-20151126/# term_ActuatingDevice [13] https://www.w3.org/Submission/2015/SUBM-iot-lite-20151126/#term_ActuatingDevice <kerry> [14]https://www.w3.org/Submission/2015/03/Comment/ [14] https://www.w3.org/Submission/2015/03/Comment/ kerry: team comment was that this group should publish it as a note of the ssn work <SimonCox> How does iot-lite interact with ssn 'skeleton'? kerry: this was done together with the web of things interest group <SimonCox> There was some discussion on list about factoring the SSN ontology, different principles that might be used. ScottSimmons: this comes a bit cold <SimonCox> OGC separates details into Observations vs Sensor-systems. ahaller2: also wonder how this interacts with the skeleton? <SimonCox> To allow different specialization choices in each. <ScottSimmons> I'll just note that the submission has multiple places to enter the OGC process, we will just need to mutually agree on the best place kerry: broadly it looks like ssn with some extensions ... has built into it the units ontology <SimonCox> If skeleton classes are stubs, then that makes extensibility easier. <SimonCox> qu-taxo is unavailable now! 404! kerry: deals with actuations, in a very light way ... has a notation of coverage, very simple geometric description that the device represents <SimonCox> QUDT is OK ... but v2.0 is now about 3 years overdue, and only rolling out in a rather punctuated fashion. <SimonCox> ssn 'skeleton' <SimonCox> so where are the observation results (values) found in iot-lite? kerry: it is my believe that the observation part can be used in the ssn <Zakim> jtandy, you wanted to wonder if this, or something similar, could be used as example around sensor data eg river flow gauge jtandy: some things we do around the emergency response example, we are keen to include sensor apis from the OGC and also stuff from this ontology kerry: i think for that use case you should be looking at the full SSN ontology jtandy: adoption rate of sensor api in OGC is still minimal? ScottSimmons: yes, it is still in research stage use ... some github players, but not yet wide adoption SimonCox: What is the relation with ssn skeleton and where is the value in the observation? kerry: it has not been aligned to SSN yet. SimonCox: It is somehow a parallel work to SSN? kerry: kind of, this should have a strong mapping to SSN, though. ... this is a metadata description and the value is delivered through an API attached to the service ... this is appropriate in IoT world <SimonCox> SSN skeleton should provide high level view of how the moving parts are related to each other, without going into detail about 'content' of any of the classes. <Zakim> SimonCox, you wanted to ask how does iot-lite relate to ssn skeleton? and to ask where are the observation results (values) found in iot-lite? <SimonCox> (Sorry - still haven't got the hang of zakim, so was a bit repetitive here). kerry: editors, please get in touch with people who want to participate in the subgroup <AndreaPerego> Thanks, and bye! <RaulGarciaCastro> bye <billroberts> thanks all - bye <eparsons> bye !! bye <kerry> bye! <ChrisLittle> bye Summary of Action Items Summary of Resolutions 1.
