Resource johnSmith
= model.createResource(personURI
.addProperty(VCARD.FN, fullName)
.addProperty(VCARD.N,
model.createResource()
.addProperty(VCARD.Given, bNode0)
.addProperty(VCARD.Family, bNode1));
Regarding the VCARD.N: does the N need to be defined somewhere? (in the
vCard ontology?) Is it a property (predicate) or just there to create the
blank node?
Is this the correct way to ask questions, by sending to the users email
address?
Thanks
Mona

There's nothing of that kind in Jena itself - it would be nice for Fuseki
See JENA-420.
