Re: Photo UC : DIG-35 Ontology

Dear Erik, Susanne,

Thanks you very much: It is an amazing job!

I have several questions / comments.

Ontology:
I also found the splitting of the ontology into several files relevant.
Did you design the ontology using a tool (Protégé?) or did you edit the
owl files with a text editor? If you have used Protégé, could you also
put the project file on the web? Have you written (or do you plan to
write) a paper about the "ontologization" of DIG35, the modeling
choices, etc.? Is the ontology covering the whole standard?

About the properties and the classes modeled: I have found several of
them described in other ontologies that seem to have a similar semantics
(or more specific or more general). For example, one could define
dig35:imageCreator has a subproperty of dc:creator.
Would that make sense to try to establish links between the DIG35
ontology with other popular ontologies, such as DC, FOAF, not
mentionning MPEG-7 (cross-ref here to the other XGR about MPEG-7
conversion in OWL)!

Instances:
The sample description you gave has been made by hand, correct? Do you
plan to also develop some automatic converters?

Photo Use Case:
Will the DIG35 / OWL conversion be central in the use case? How do you
plan to incorporate this work in the interoperability problems described
so far?

Best regards.
