<Holger> http://www.w3.org/2005/Incubator/ssn/wiki/Use_Case_Device
Used MMI Use case number 10
Holger has added other sub-uses cases
Laurent wants more details to complete the use case and build examples
e.g. the info about the sensor
Laurent will use the same template
Need at the top page to record the connections between the use cases.
<scribe> No progress on the data discovery use cases
Kevin: issue with working the use case is touching domain ontologies
Kevin see two motivations for use cases
Motivation for the work
Validation of the ontologies
<Danh_DERI> +q
Laurent 2nd one is important
Kevin issue do the complete validation ican be difficult
Danh How can we validate the ontology (general question)
Holger The ontology covers the information which an application need
Danh Do we have participants which will build an application based on the ontology = an "implemntation" partner like in other W3C groups?
Holger as an XG we may not do the full cycle It is not in the list of deliverables
Laurent It would be good to define a period where we receive feedback
Holger Time is an issue
Kevin Agree that time is the issue Validation may not be complete
Laurent Other W3C groups find it difficult to do validation of their ontologies
Michael has sent a new version of the ontology following discussion at the f2f meeting
<Danh_DERI> +q
<krp> +q
Raul's question/comment how much will we cover the observation ontology?
<krp> How many concepts are missing?
Raul wants to add a couple of properties on the observation side
Danh ask what metadata is used for
Raul it's an observation metadata
Danh This part is confusing
Raul This is a place where people can insert more information
<krp> Yeah, I'd agree, a metadata class is disconcerting
Danh There are other way to extend it
The Metadata part has been proposed by Raul (last message in the mailing list)
Kevin This is a transposition of O&M into the ontology Question what is missing
Raul Time and Quality
Luis Often two different times for an observation: sampling and result
<Danh_DERI> +q
Observation has a time Result is only a value now but may also have a time
Danh Location information is "outside" or "inside" ?
<Danh_DERI> +q
Holger W have the placeholder for it as an external ontology
<michael> we just didn
Danh We have not defined a range for the result time (precise the datatype of the class)
<michael> we just didn't discuss it at the face-to-face. The ontology was just meant to show what we discussed at the f2f.
(datatype or class)
<Luis> +q
Arthur in the Sensor Michael sent us, Sensor and Device - how they relate to each other
f2f discussion : Sensor = the abstract description and Device the physical thing
That was Michael's interpretation
<krp> Did we manage to get hold of the wallchart photos from the f2f?
<krp> (he says, regretting he didn't have a camera on him that day)
<rgarcia> +q
Luis SensorMl has a hierarchy - We have to precise this hierarchy for System, Process, Sensor Device
<Arthur> +q
Luis Currently we don't track these comments
<michael> I jotted down the picture on the minutes from the wall chart
rgarcia: need to document the ontology further on these points
Arthur WebProtege can we use the versioning?
Holger We have not managed to set it up
<krp> Shame... the photos of the various options would be handy to refresh my brain ;)
<scribe> ACTION: Arthur to check possibility to install Protege [recorded in http://www.w3.org/2009/12/02-ssn-minutes.html#action01]
<michael> I thought someone did take pictures
You can put them of flickr too and create a group
Holger need to track the ones done by Manfred and Amit
<Danh_DERI> +q
<rgarcia> WebProtege also helps to track changes and discussions
Holger sums up what was discussed at f2f o common ontology tools (webprotege)
Luis describes how the mmi repository record the changes every time you upload the ontology
Danh's colleague Richard can help/propose alternatives
<michael> Isn't there a w3c tracker?
Luis wants to know how we synchronise the editing of the ontology - we need a process - can use a wiki page in support of it
W3C has an issue tracker
<Arthur> http://www.w3.org/2005/06/tracker/
Discussion two sides: tasks and changes at the ontology level
Current processs: Michael as the main custodian Feedback on the ontology through the meeting
Intent: Ontology editable by all and a visible tracking thread of changes
Luis example: 1) submit a change 2) discuss in the meeting 3) make the change
+1
<krp> +1
<Danh_DERI> +1
<rgarcia> +1
<Holger> +1
Holger do we agree on this new approach (answers are above)
<scribe> ACTION: Holger to contact W3C to have a tracker [recorded in http://www.w3.org/2009/12/02-ssn-minutes.html#action02]
Laurent Will add stuff on Semantioc Markup page - Topic to be handled at next meeting
