Hi all, I've been looking at the ontology Jennifer Golbeck presented for representing information about conferences. Overall, the ontology is fine and captures the domain in about the right amount of detail, and there are only two areas in which I think that the ontology needs clarification or amendment. - Date and Time Why are these resources rather than datatyped literals? (I'm assuming because there are inverses of the hasStartTime/hasEndTime properties) What's the relation between times and dates? Are there detailed properties which give the components of dates and times, or are they completely opaque? I'd be in favour of datatyped literals instead of resources here (I'm not sure how useful the inverse properties above are likely to be), preferably as XML Scheme dateTime (CCYY-MM-DDThh:mm:ss) - Conferences/workshops have at least one start/end date (i.e. are a subclass of the restriction of things with at least one start/end date). I'm not sure that this makes sense - can a conference have more than one of each? Suggest this be changed from owl:minCardinality to owl:cardinality -- Nick Gibbins nmg@ecs.soton.ac.uk IAM (Intelligence, Agents, Multimedia) tel: +44 (0) 23 80598347 Electronics and Computer Science fax: +44 (0) 23 80592865 University of Southampton ================================== This is the TEMPORARY discussion list for the W3 Semantic-Photo History Project.
