Agenda/Minutes for Device Ontology Meeting 2008.09.02

Agenda

  • Logistics: Welcome, Minutes Review, Agenda Review
  • Status of last action items
  • Review new version of the ontology
  • Review Terms page
  • Discuss proposed classifiers
  • Tracking strategy: 1) Reactivate TRAC? 2) Activate SF tracking (since we're already using the SVN there)?

Comments on Last Minutes/Last Meeting

Status of last action items

  • [Carlos] Update SVN repository with versions discussed. 
    • Done: the two ontologies (the OWL file and the diagram in both cases) were tagged 20080819_draft_2a and 20080819_draft_2b, respectively.
    • deviceontterms.html (with the contents of the Terms page) was put under version control in SVN.
  • [Carlos] Update diagram per 2008-08-19 conversation 
  • [Carlos] Look at paper: Done. Extracted part of the OntoSensor ontology for comparison.
  • [Bob] Look at paper
  • [all] Contribute list of your known classifiers for sensors and samplers
    • Roy Lowry sent this email with attached spreadsheet sampler_classification.xls. He says: "In summary, the most important categorisation is the nature of the sample collected, which needs to be described by a multi-level hierarchy." -- more details in the email.
    • Jesper Zedlitz sent this email. : "I asked our Physical Oceanography research unit how they categorize their instruments." -- more details in the email.
    • John Graybeal sent this email: "The classifiers for sensors on the Shore Side Data System mostly resolve around functionality.  We have two types of equipment, sensors and platforms." -- More details in the email.

Review new version of ontology


The changes incorporated in the new version are:

  • Deployment no longer a subclass of Process.
  • System is now a subclass of Process.
  • Identification properties captured with a new Identifier class as a possible MetadataGroup associated with a process. (MetadataGroup comes from SensorML.)
  • This is in general a bit closer to the SensorML model [1].
  • The distiction between "atomic" and "composite" processes is explicit in SensorML.
  • Also, contrast with OntoSensor [2].

References:

  • [1] The diagram ontosensor3.png shows part of the OntoSensor model from here.

  • [2] Carlos created a roughly corresponding class diagram from one of Mike Bott's slides (from MMI workshop last week) describing SensorML processes.

Comments during telecon

  • Make explicit composition of processes (this will most likely follow SensorML as well).
  • Deployment may not be needed for our purposes.
  • In SensorML, a platform does not produce any measurements, but the sensors attached to it.
  • Clarify "platform" concept in our ontology. Again, look at OntoSensor.

Review Terms page

  • Need to update it to be consistent with current version of ontology.

Discuss proposed classifiers

  • See referred emails above.  Need to specify a top-n classifiers.

Tracking strategy

  • Not discussed.
