<aharth> is the webex online already?

<ahaller2> yeah, same problem as last week

<mlefranc> let's try rendez-vous today ?

<mlefranc> https://rendez-vous.renater.fr/sdwssn

<KJanowic> Is the WebeX not set up correctly or is it just me?

<ahaller2> no, as usual, not working

<ahaller2> https://rendez-vous.renater.fr/sdwssn

<mlefranc> Jano, try this: https://rendez-vous.renater.fr/sdwssn

patent call https://www.w3.org/2015/spatial/wiki/Patent_Call

Decide on Pull Request #916 - Reject?

<ahaller2> https://github.com/w3c/sdw/pull/916

PR #916 is on relaxing axioms, there were some disscusions among editors

<mlefranc> https://www.w3.org/2015/spatial/wiki/Generic_vs_Specific_Modeling

Armin rejected the PR

<KJanowic> and rightfully so

mlefranc: there might be a problem with strict axioms related to ssn:isPropertyOf a owl:FunctionalProperty and ssn:hasProperty a owl:InverseFunctionalProperty... as mentioned in the PR's discusions

KJanowic: I stand by the arguments that Simon and I made in the PR's discussion
... I recommend not to touch current stage as It still holds in most of the case

mlefranc: we need to relax the axiom ssn:isPropertyOf a owl:FunctionalProperty

KJanowic: the relaxed case can be still done with SOSA

mlefranc: the ssn:isPropertyOf a owl:FunctionalProperty will lead to reasoning effect : two features of interest will be same if they are linked to the same property

<ahaller2> ACTION: mlefranc to remove ssn:isPropertyOf a owl:FunctionalProperty [recorded in http://www.w3.org/2017/06/13-sdwssn-minutes.html#action01]

Progress on Action-362 - Transferring example from https://www.w3.org/2015/spatial/wiki/GageHeightExample to WD

KJanowic: I can have it ready when mlefranc issues the PR

Progress on Finalising Pull Request #912, fixes to DUL Alignment

<ahaller2> https://github.com/w3c/sdw/pull/912

<KJanowic> https://github.com/w3c/sdw/pull/923

KJanowic: the change is in PR # 923

<KJanowic> "Requested bug fixes to correct the SSN/SOSA alignment to DUL"

Progress on ISSUE-198 - Actuator and Sampler not in Figure 2/3

ahaller2: we can close AC on PR #912
... Raul updated some new figures

KJanowic: but I don't see the changes in the documents

IoT device example that was sent over email

<mlefranc> see email Draft for an answer to Tobias's comment at public-sdw-comments

<aharth> the light has a uri: <http://localhost/light>

<aharth> GET on <http://localhost/light> returns "true" (in RDF)

<KJanowic> This seems confusing results, FOI, and observedProperties

<aharth> PUT "false" (in RDF) to <http://localhost/light> would switch the light off

<KJanowic> We have this

<KJanowic> Very important remark by Danh, observations are about the past

<KJanowic> exactly!

<aharth> ahaller2: example written out on github

<aharth> +1

<mlefranc> https://www.w3.org/2015/spatial/wiki/IoT-Device-Example

<KJanowic> +1

<mlefranc> please edit this wikipage

<KJanowic> Thanks for the Example Tobias/Andreas!

aharth: we will move the discussion in the wiki page, and refer it in the mailling list

<KJanowic> ok

<KJanowic> fine with me but I will not be there
