Re: Has anyone a working vCard Schema

Hello again,

as I needed the Schema today, I came up fixing it myself. Attached is
the RDF-Schema and an example that includes all examples of the TR
(http://www.w3.org/TR/vcard-rdf). Maybe someone finds them useful,
comments are *highly welcome*!! (As I use it as an example in my Phd
thesis.) I did not check the RFC for complete conformance yet, as I
suppose Renato Iannella did so already...

Although rather complicated, I did not change the structure, so the TR
is still valid (except for minor correction regarding the types).
However, there are two things annoying me:

(a) The MIME Spec (RFC 2426) requires (MUST) that a vCard object
    contains "FN", "N", and "VERSION". How can I represent this
    elegantly in RDF?

(b) To allow range/domain checking, one has to come up with many ugly
    structures like
      <vCard:N rdf:parseType="Resource">
        <rdf:type rdf:resource="http://...vCard.rdfs#NPROPERTIES"/>
    This is mainly because of extensive use of anonymous resources
    which I do not like much. Now this is a matter of style, so I
    would like to ask the community if the above way is really the
    best way or if a explicit property like "hasN" connecting to a
    explicit resource "N" (how I would have done it) were better.

Also, I wonder if there are proposals to restrict bags, but this is
another posting...

        Thanks for your patience, Gerhard.
