<Luis_Bermudez> there is a terrible background noice
<AmitS> +Prateek -> Amit Sheth
<Holger> ScribeNick: rgarcia
Michael: The page describes the main concepts of the ontology
<AmitS> This is noce-- where would you model error conditions?
Michael: and how they link to each other
Luis: Sensors may be losing battery
Michael: We can model this in the Capabilities "box"
<Payam> what about the measurement time?
Luis: In non-normal functioning conditions the measurement of the sensor can be innacurate
<AmitS> one tentative view-- OWL-DL may not be sufficient, we may have to recognize the need for rules in modeling sensors- Amit
Michael: Observations still need to be incorporated in the ontology
<kerry> butthe time of operation of a sensor might be part of a capabilitydescription
Amit: There is the need to model the time when the sensor is operational. Where do we model it?
<kerry> perhaps time is part of the "condition" of the capability
Amit: And how?
<krp> Though that condition is on the result model isn't it? Would the operational time be an "operational restriction" in Physical Properties?
Michael: existing ontologies may already include the concepts needed to model time, but we may want to model some things differently
Payam: some things are "global" and must be synchronised across the ontology (e.g., timezones), where will be this modelled?
Danh: ow can we model a sensor that is moving and whose movement is detected by other sensors?
<AmitS> As with time, location will need to be model separately
<laurent_csiro> Basic time zone stuff described in http://www.w3.org/TR/owl-time/ but limited applicability because there is no logic between the choice of daylight saving times.
Luis: we have already in SensorML the location of the observation and the device separately
<michael> yes and how to express them in OWL
Luis: it is better not to re-discuss but to decide the parts of the ontology to be further developed
Arthur: regarding location, a concept "Motion" could represent this
<Arthur> concept would be actuator, and one possible actuator cold be motion.
Amit: Types of sensors and the grounding of particular sensor are different
Michael: With the current ontology both things can be represented (with the TBox and ABox)
Luis: Do not reinvent the wheel for mobile sensors. We can reuse existing approaches (OGF) and model them in RDF
<michael> more time for discussions sounds good
<michael> demo could be over lunch?
Kerry: Avoid the keynote speaker
Some interesting demos could be one regarding markup and another regarding using multiple ontologies
Proposal to split demos in 2 sessions, one for each main topic (Ontology + Annotation)
Laurent: Insert in the agenda the discussion of where the group is and where we will go
<kerry> I could not hear laurent well -- if it was discuss where we go next +1
<laurent_csiro> It was know where we are the beginning and then get time for people working on the same deliverable to coordinate their efforts towards the deliverables
Holger: Kerry will chair next meeting
<scribe> ACTION: Everyone to take a look at the use cases (discuss, add, etc.) for next meeting [recorded in http://www.w3.org/2009/09/01-ssn-minutes.html#action01]
<laurent_csiro> I've worked as the Australian Office Manager on a conference for web developers Web Directions South 600+ attendees Kerry will do a presentation on the SSN-XG
