<laurent_lefort_cs> Scribenick: Michael

Progress on the ontology

<laurent_lefort_cs> Michael: work on the DOLCE alignment plus adding the definitions

<laurent_lefort_cs> ... Michael has done a pass on the definitions imported from elsewhere

<laurent_lefort_cs> ... Make them more consistent across the board

just give me a tick, back in a sec

<laurent_lefort_cs> Laurent: comments on changes on the way we use dc:source.

<laurent_lefort_cs> ... we now put the text and the url together.

sorry, back now

Andiy example

accelerometer, 4 measurement ranges 4 frequencies. Plus an example of accelerometer attached to a knife

the knife is the platform and feature of interest.

<Payam> can you add the link here please

I think http://www.w3.org/2005/Incubator/ssn/wiki/Special:ListFiles

<Payam> found it; http://www.w3.org/2005/Incubator/ssn/wiki/Special:ListFiles

<Payam> +q

example: http://www.w3.org/2005/Incubator/ssn/wiki/images/4/4e/SSN-kitchen-example-extract-sensor.jpg

<laurent_lefort_cs> Andriy: we may need examples with other capabilities (precision and accuracy)

Payam: XG's doco should point out what's possible beyond the examples.

<krzysztof_j> +q

<krzysztof_j> depends on which version you use


Krzysztof: feature of interest should be connected to other things.

<Payam> possibly I have used an old version

Krzysztof: what are the meanings on the diagram

Laurent diagram drawn with CMAP

Laurent: 'is a' types an idividual
... 'are' is subclass


<laurent_lefort_cs> Laurent: explaining the graphical conventions used by CMAP

<laurent_lefort_cs> ... the arrow "are" corresponds to rdfs:subClassOf

<laurent_lefort_cs> ... the arrow "is a" corresponds to rdf:type (instance to class relation)

<laurent_lefort_cs> Let's look at other examples:

<laurent_lefort_cs> http://www.w3.org/2005/Incubator/ssn/wiki/Semantic_Sensor_Net_Ontology#Ontology

<laurent_lefort_cs> http://www.w3.org/2005/Incubator/ssn/wiki/SSN_Sensor#Measuring


<krzysztof_j> +q

<krzysztof_j> ack to michael

<Payam> +q

Michael: We all had problems interpreting these diagrams, is that a problem for the documentation?

Laurent: lots of people use this.

Krzysztof: the diagram puts 'is a' with a different meaning to how OWL uses this relation.
... can we change this

<krzysztof_j> is a = instance-of and are = is a, right?

<laurent_lefort_cs> Yes

Laurent: no we can't change
... yes it might be confusing but tool had advantages: easy to move things around in diagrams, remove things,

<Payam> +q

Laurent: so can make diagrams that map to intuition of ontology.

Payam: agree the blue lines are confusing.
... what was sent earlier today (Raul) is an option

<laurent_lefort_cs> http://lists.w3.org/Archives/Public/public-xg-ssn/2010Aug/0022.html

<Payam> or perhaps Raul's version and the current diagrams can be complementary

<krzysztof_j> why not jambalaya?

<krzysztof_j> ok

<Pramod> +q

Pramod: does the example use units?

Andriy: yes the ontology example has units restricted e.g. the numbers are restricted to gravity

Laurent: summary: we have example with measurement capability and observation that links to feature of interest

<laurent_lefort_cs> Example by Payam: http://www.w3.org/2005/Incubator/ssn/wiki/File:SSNSample.jpg

Laurent: also second example from Payam

Payam: it has measurement capability, data parts, features. added some classes (observation service...)

<laurent_lefort_cs> http://www.w3.org/2005/Incubator/ssn/wiki/Semantic_Sensor_Net_Ontology#Ontology

<krzysztof_j> (may also be an alternativ for the visualization http://protegewiki.stanford.edu/wiki/OntoGraf)


<Payam> OntoGraf doesn't show the property labels - or I couldn't fined how to do this

<Payam> fined

<krzysztof_j> you mean procedure?

<krzysztof_j> michael: you mean Procedure as subclass of method, right?

it's actualy called process in the ontology

Laurent: use payam's example for deployment etc, and Andriy's for measurement, need another for process

<Payam> +q

<laurent_lefort_cs> http://www.w3.org/2005/Incubator/ssn/wiki/SSN_Observation#Observation

Payam: observation class ... should have link from sensor to observation

Michael: it's in the latest version

<Payam> +q

Laurent: I've been working on review

<laurent_lefort_cs> Adding references and putting everything into a single page

<laurent_lefort_cs> Payam and Cory's ontologies are less well covered than the others

Dolce Ultra Lite alignment

Michael: DUL alignment meeting after this

<krzysztof_j> i will look for something


<krzysztof_j> but essentially we can copy only the direct super class into the figure

Laurent: Augmented reality email from the list

anyone interested?

Laurent: explaining context

<krzysztof_j> sounds interesting


<Payam> bye
