Oh OK.. so there's also a newer version. I've referenced
http://www.w3.org/TR/2001/NOTE-vcard-rdf-20010222/. One of the first
reactions was that it doesn't support vCard 4.0 (which also the doc you
reference doesn't).

Perhaps you should share that directly on apps-discuss.

That's true. The only problem arises when you want to process that data also
as plain old JSON. In that case you have to define some constraints (e.g.
the field names to be used) so that the context doesn't have to be evaluated
by those clients. Our "profile" media type parameter addresses that issue.
So all you would have to do to also support plain JSON clients, is to define
those restrictions somewhere, assign it an IRI and put it into that

Thanks for the background infos Ivan.
