I think that since vCard is so widely adopted, in one of its 
standardized forms or property soup, that we should provide the most 
1-to-1 mapping from vCard we possibly can to ease adoption. Leave vCard 
as it is (even when it is somewhat unappealing) and use RDFS or OWL to 
add the necessary links we require. I fear that if we change too much 
in it, people will think that "uh, they say it is vCard, but it is not 
all vCard" and reject it on that first look. 

I think we should think of vCard as being a card, but that it belongs to 
a foaf:Agent. That is, I hope we could have a foaf:has_vcard property 
with domain foaf:Agent and range vcard:VCard. Would it then be a 
reasonable extension to vCard to have the converse, vcard:belongs_to?
