<laurent_lefort_cs> Payam will only be on the IRC - The problems with the EU bridge for Zakim are still happening
<Payam> I am in a conference session; haven't tried the EU bridge
who is pm0018?
<Payam> It was me :)
Laurent - do you want me to scribe?
<laurent_lefort_cs> sribenick: kerry
( no comments from last week)
<laurent_lefort_cs> 2 actions for Laurent
Laurent has emailed summary of last weeks discussion. 2 actions for laurent.
<laurent_lefort_cs> Laurent: Zakim status http://www.w3.org/2005/Incubator/ssn/track/actions/32
laurent: bridge problem continues. is out of control of W3C.
<laurent_lefort_cs> Action 30 http://www.w3.org/2005/Incubator/ssn/track/actions/30
<trackbot> Sorry, couldn't find user - 30
laurent: location of ontology
after the XG
... been in contact with W3C folks -- answer so far is a request to state what we want to do after XG close.
<laurent_lefort_cs> Lead to Issue-9 http://www.w3.org/2005/Incubator/ssn/track/issues/9
David kelsey: would like to see persistence in an open forum
david: possibly sourceforge
<laurent_lefort_cs> Laurent: time to explore options and record expressions of interest from XG participants
<laurent_lefort_cs> Kerry: Discussed this with Laurent. 1st option is Member submission, 2nd option is to continue via a working group
kerry: perhaps w3c member submission or start a working group?
<krp> Is what we do with the ontology version at the time of the XG close (put on the W3C site) distinct from continued development after XG closes?
<laurent_lefort_cs> Laurent: 3rd a way to continue to host the ontology
laurent: or find a way for W3C to host it
michael: is there any precedent for W3C hosting?
laurent: yes. another XG has one
on a W3C wiki, but this does not get the namespace right
... there is a 3rd party one too (epimorphics) that is being hosted on the website: the organisation ontology
krp: is the one on the wiki still being maintained?
<krp> is that a technical restriction, or just that the working group is inactive now?
<krp> i.e. do W3C freeze the wiki one the XG is done?
laurent: the epimorphics one will be -- associated with egov linked data
(aside to kevin) -- I think it is a bit of both, but I'm not sure
to be continued. Members to consider!
laurent: michael explain current position and laurent to explain example he is working on.
michael: (with reference to email to list today) : 1st one is Payam's suggestion interpreted in OWL by Michael with an example
payam: have you had a chance to look at this?
(payam is not on the phone)
(no response from Payam)
kevin: are any of the constraints
used over different ranges or only in a particular
... are has-constraints intended to be used only some ranges. Why not subclasses of those things?
<Payam> my protege couldn't open the file; I willtry it this afternoon again
kevin: e.g enviromental survival range and env operating range seem to be specific constraints. Is there a contraints that can be used in all places?
michael: maybe... this is like what we did before.. perhaps just one constraint would do
kevin: should survival and operating range be explicit or subclassed (scribe having trouble keeping up)
michael: will be here for next meeting but away from email between now and then
<michael_> I'm not on email for the next week, but I will be attending the next conf call.
<laurent_lefort_cs> Laurent: main page with list of examples: http://www.w3.org/2005/Incubator/ssn/wiki/Semantic_Sensor_Net_Ontology
sub-topic to be carried to next meeting: participants please look at the proposals on the email list!
laurent: see example in link:
have split into general example plus semantic markup example
plus hydrology example
... we still need one for operating model
michael: yes we do
laurent: is the marine/ocean environment different/challenging?
david: could be a good reference environment for mobility (cruise to waypoints for measurements)
laurent: observation geometry and
mobility maybe should be separated -- eg. to cover remote
sensing vs mobile phones
... has also done a calibration example: does anyone have experience with this and can comment?
(hold for next week)
laurent: agricultural example:
... see stuff on the page linked: looking at bringing in the units and other things for this
... might also use product metadata and spatial locations/coordinates from neesgrid
... worrying about how to put the modules in together -- have a little script to help
... uses the XG ontology plus externals to describe a real system.
kevin: looks fine -- not quite at
the level that I'm working
... could yet have something to say about adapting rates depending on stuff from other sources
... at Soton more about the data than the sensors
... Spanish link re doing more low-level things
laurent: looking for contributions from people looking at sensor networks in different ways to get coverage
kevin: I might be able to
contribute a calibration example, but perhaps not in the time
... upm is doing the ontology but the hardware (elsewhere in Spain) is delayed
kerry: expecting new member from
open university uk
... ssn10 workshop call for papers is out
kevin: request for more detailed timeline up to end of the XG
laurent: (brief outline of
timeline) will flesh out. What happens after the XG is an
important factor in this
... 2 rounds of ontology release plus the hard part of the report to start asap
