<laurent_csiro> scribenick: Arthur
<laurent_csiro> Laurent presented the SSN XG ontology to OGC TC meeting
<laurent_csiro> One critical point: alignment between ssn:Observation dul:Situation
<laurent_csiro> Issue to watch: impact of disjoints in DUL constraining the use
<michael> keeps dropping out?
<michael> laurent's voice that is
<kerryt> everything is fine for me
<kerryt> might be the storm
<michael> yeah my skype just dropped out - we have a thunder storm here
Michael: we could make our ontology more precise to prevent inheritance from DUL classes which can lead to conflicts
Laurent: another candidate for conflicts are situations and events
Michael: Observation is something that has happened, it can be an event or a set of events but don't has to
Laurent: we don't have to change the ontology, but we need to document this kind of explanation
<kerryt> An observation can be related to an event or set of events but is not an event itself
<kerryt> Note that sensing is what you do to make an observation. we see that the process of making an observation is an "event" , but not the observation itself
<laurent_csiro> Observation page: http://www.w3.org/2005/Incubator/ssn/wiki/SSN_Observation
<kerryt> (excuse me ) arthur-- no. This is not right either. It is not a container of events. It can be "related by a property" to an event.
<Pramod> +q amit
<kerryt> An ssn:observation is not a dul:event. It is the record of an event. The process of sensing is a dul:event, but the ssn;observation is the outcome of that processing and is not an dul:event itself
<Pramod> just show a link from our ontology to
<Pramod> the ontology on situational awareness
<laurent_csiro> ACTION: Michael to add information in SSN_Observation page [recorded in http://www.w3.org/2010/12/15-ssn-minutes.html#action01]
<trackbot> Created ACTION-65 - Add information in SSN_Observation page [on Michael Compton - due 2010-12-22].
<Pramod> can we map two observation to a reference ontology?
<kerryt> don't duplicate this to avoid risk of confusion
<laurent_csiro> The comment of the Observation class in the SSN ontology says: Observation here records a Situation (the estimation of the value of a Property) and a description of the method that was used (along with the participants), while O&M interprets an Observation as the event itself; there must, however, have been an event that lead to our situation, so both are records of events. The distinction is between the event itself and the record of what happened in that
<laurent_csiro> reports from other XGs
<michael> I'm away from Tuesday lunch (our time)
