Hopefully I will be able to also provide some feedback later today. Maybe this very new document is of interest:
vCard Ontology For describing People and Organisations W3C First Public Working Draft 2 May 2013 http://www.w3.org/TR/2013/WD-vcard-rdf-20130502/ It is somewhat strange that FOAF is not mentioned in that document. It think that this is mainly a result of the fact that different communities were involved.
