Hi Jeff,

I'd see it as a definitive advantage if I could automatically generate software (or at least parts of it) from an application profile. I'm thinking about Java XML-beans and similar frameworks. Do you know if there is anything similar to that for OWL? If not, we'd have to de-tour OWL-XSD and then generate it from XSD.

All the best,

Lars
