Simon, all, > There's already a slight problem in vCard's treatment of bday; it > includes xsd:gYear, which is not permitted in OWL2-DL, and it does not > include xsd:string, which is available, and which is required by the RFC. If I declare the use of xsd:gYear in my ontology, can I use it then? I'm not familiar enough with OWL to answer that question myself, but the way I read ยง9.4 of the OWL syntax [1] I can use any datatype. Can someone more familiar with this topic shed some light on this? > OWL2-DL allows for facets on dataTime to specify a minimum and maximum > time point value, which can be used in restrictions on individuals to yield the > appropriate models; however, this approach is not ideal. What would an ideal approach look like? [1] http://www.w3.org/TR/owl2-syntax/#Datatype_Definitions Thanks, Lars
