20:15:05 <KJanowic> There will only be one last meeting of the entire sdw group. We as ssn group can meet up to 3 more times.
20:15:18 <ahaller2> q?
20:15:18 <SimonCox> Me also not available on 20th
20:15:29 <KJanowic> Comments on the timelines?
20:15:55 <ahaller2> topic: Progress on Action-362 - Extend canonical examples with coastal water body example using rdfs:subclassing and punning

20:16:36 <KJanowic> https://www.w3.org/2015/spatial/wiki/GageHeightExample
20:17:05 <ahaller2> KJanowic: combined action items on this page
20:18:05 <ahaller2> ... real example from the USGS
20:18:21 <mlefranc> * reload page for better formatting
20:18:31 <ahaller2> ... data on discharge and on streamgage
20:22:33 <ahaller2> ... sosa:observedProperty examples: GageHeight ; in Observation is either a class or an instance of sosa:ObservableProperty
20:23:21 <ahaller2> ... Alternative 2 is using punning, an instance of an instance
20:23:57 <mlefranc> q+
20:24:20 <ahaller2> ack mlefranc
20:24:24 <SimonCox> q
20:24:31 <SimonCox> q+
20:26:29 <ahaller2> mlefranc: observedProperty has a cardinality restriction, makes GageHeight1 = GageHeight
20:26:33 <ahaller2> q+
20:26:57 <KJanowic> https://water.usgs.gov/edu/streamflow1.html
20:27:24 <ahaller2> ack SimonCox
20:27:47 <KJanowic> SimonCox: You forgot phenomenonTime
20:27:59 <KJanowic> agreed, it was not avaibale
20:28:37 <KJanowic> s/avaibale/available
20:29:32 <ahaller2> ack ahaller
20:29:45 <KJanowic> SimonCox: it is a matter of how you interpret the data. Actually it is most likely the sosa:phenomenonTime
20:29:54 <KJanowic> kj: Im guess Simon is right and i was just sloppy
20:30:08 <KJanowic> s/Im/I
20:30:38 <mlefranc> q+
20:30:54 <ahaller2> ack mlefranc
20:30:55 <KJanowic> Ahaller2: We make the ontology more flexible and we are just fixing an error. We got requests around examples. In order to accommodate them we had to make some changes.
20:31:10 <mlefranc> https://www.w3.org/2015/spatial/wiki/Generic_vs_Specific_Modeling
20:31:20 <KJanowic> Maxime: If we can relax the axioms in the ontology than let us do it, it will be for the best.
20:32:20 <KJanowic> Maxime: Question is whether we can still modify the normative sections.
20:32:34 <ahaller2> q?
20:32:45 <KJanowic> Ahaller2: yes, but it only relaxes the axioms so we are broadening the scope
20:33:02 <KJanowic> Ahaller2: to contact w3c
20:33:06 <ahaller2> Action: ahaller2 to ask Francois if we can relax axioms to accommodate punning
20:33:06 <trackbot> Created ACTION-371 - Ask francois if we can relax axioms to accommodate punning [on Armin Haller - due 2017-06-13].
20:33:30 <ahaller2> q?
20:33:47 <KJanowic> Ahaller2:  there is also the potential to just change the code. Not perfect but I guess this is what will happen on the long term anyway.
20:34:01 <KJanowic> KJ: Yes
20:34:20 <ahaller2> topic: Implementation of proposal for alignment as of https://www.w3.org/2015/spatial/wiki/Events_and_Situations for ssn:Observation
20:34:27 <KJanowic> q+
20:34:39 <ahaller2> https://github.com/w3c/sdw/pull/912
20:34:41 <ahaller2> ack KJanowic

20:36:32 <ahaller2> KJanowic: Deployment class becomes a simple alignment, a subclass of Event
20:37:00 <ahaller2> ... sosa:FeatureOfInterest becomes a unnamed union of Event and InformationEntity
20:37:06 <mlefranc> w+
20:39:06 <ahaller2> ... sosa:usedProcedure can not be a sub-property of satisfies anymore
20:40:12 <ahaller2> ... those things that have not been identified as an Observation, but use observationResult, these instances can be aligned
20:41:32 <ahaller2> ack mlefranc
20:41:52 <SimonCox> I just lost audio
20:42:05 <KJanowic> Maxime: Quality added because you can observe a sensor capability.
20:42:17 <KJanowic> q+
20:42:58 <KJanowic> q+
20:43:28 <ahaller2> ack KJanowic
20:44:36 <ahaller2> q?
20:44:38 <KJanowic> Maxime: I am fine with the new axiom
20:45:06 <KJanowic>  Kjanowic: Observations of the accuracy of a sensor are observations
20:45:28 <KJanowic> Ahaller2: you forgot the change history. You fixed an ERROR so we need to point this out.
20:45:56 <ahaller2> q?
20:46:05 <ahaller2> topic: Progress on Action-356 to create a list of axioms that do not need implementation evidence
20:46:35 <KJanowic> Ahaller2: there is a wiki page created for last week;s meeting.
20:46:44 <KJanowic> s/week;s/week's
20:46:45 <ahaller2> https://www.w3.org/2015/spatial/wiki/Implicit_Implementations_entailed_by_Axioms
20:47:15 <KJanowic> Ahaller2: This needs to be transferred to our usage page.

20:47:33 <mlefranc> q+
20:47:35 <ahaller2> ack KJanowic
20:47:37 <KJanowic> Ahaller2: Raul, can we do this together?
20:48:29 <SimonCox> q+
20:49:25 <ahaller2> ack mlefranc
20:50:11 <KJanowic> SimonCox: Similar question wrt OWL-Time. Response was that this could be an example that styles the data, e.g., into a html page.
20:50:14 <SimonCox> q-
20:51:05 <KJanowic> Maxime: Can we exploit the existential quantification axioms to generate implementation evidence?
20:51:06 <KJanowic> q+
20:51:23 <ahaller2> ack KJanowic
20:52:43 <KJanowic> KJ: very good idea but may not be acceptable
20:52:52 <ahaller2> q?
20:52:57 <ahaller2> topic: Sensor/Actuator in Figure 2/3 as of ISSUE-198
20:53:52 <mlefranc> https://github.com/w3c/sdw/pull/905/files
20:54:07 <KJanowic> Ahaller2: the sampling ended up in the figure but it does not exist any more. Pull request was rejected.
20:54:19 <KJanowic> q+

20:55:37 <ahaller2> ack mlefranc
20:55:48 <KJanowic> Kjanowic: actuator and so forth still missing from the SOSA and SSN overview figures.
20:56:34 <KJanowic> Maxime: Can be duplicated to illustrate the actuator part. Sensing has to be removed.
20:57:14 <KJanowic> Ahaller2: Follow up on email to remove sensing.
20:57:26 <ahaller2> q?
20:57:54 <KJanowic> q+
20:57:58 <ahaller2> ack KJanowic
20:59:09 <mlefranc> * (I will have to leave in 5, important interview tomorrow)
20:59:37 <KJanowic> We will show figures 2-4 hundreds of times, the figures have to be correct
21:00:47 <ahaller2> q?
21:00:56 <KJanowic> ahaller2: email reminder to Raul; issue remains open
21:01:07 <ahaller2> topic: Progress on Action-364 to add text to explain role of sampling in SSN examples on room/ice sheet
21:02:01 <KJanowic> SimonCox: Been working on 363, not yet 364.
21:02:17 <ahaller2> topic: Progress on Action-366 to add examples from O&M converted to SOSA/SSN
21:02:29 <KJanowic> ahaller2: let us move the discussion of 364 to next week
21:04:21 <SimonCox> s/363/366/
21:04:33 <ahaller2> topic: Progress on Action-367 for each editor to add one example that uses as many classes/properties as possible
21:05:21 <ahaller2> https://github.com/w3c/sdw/pull/911
21:05:32 <KJanowic> Ahaller2: A smartphone example using only SOSA. See pull request 911.
21:06:12 <KJanowic> Ahaller2: Pull request also fixes broken links
21:08:30 <SimonCox> q+
21:08:34 <ahaller2> q?
21:08:36 <KJanowic> ahaller2: so we have the iphone, kj's example, the room examples, and so forth. We we need more?
21:08:56 <mlefranc> q+
21:09:21 <KJanowic> SimonCox: Do we need a short section at the beginning of all examples?
21:09:30 <KJanowic> q+
21:10:41 <KJanowic> ahaller2+simoncox: sometimes it makes sense not to talk about the sample but directly about the FOI.
