Hi,

I'm in favour of having a separate property for encoding the version  
IRI. The use of versionInfo for all kinds of content is widespread;  
requiring an IRI there would break backward compatibility.

As Michael says, this property is to be used solely on Ontology  
elements, it therefore seems natural to encode it as OntologyProperty.

Best,

	Rinke
