    I think the problem is I haven't seen your proposal. Could you
e-mail it to me or post it to
semantic-web@w3.org? That may be why we crossed-wires.

Since I hadn't seen your proposal I was just responding to the fact that
the current spec would likely prefer one to use:
instead of  <v:n>Stevenson;John;Philip,Paul;Dr.;Jr.,M.D.,A.C.P.</v:n>,
since, as you pointed out, "v:n" is for components of a name, not
strings per se, so its range is members of the v:Name class.

I don't see any problem with your proposal and agree with what bit of it
I've read.

 Is your point that you would prefer


i.e. using card:N as a class rather than our current use of v:n as a

Currently we would accommodate that sort of thing by having a URI
(possibly blank node) for the name itself (similar to your usage of

 http://www.example.org/person v:n www.example.org/example_name.
 http://www.example.org/example_name a v:Name.
 http://www.example.org/example_name v:given-name "George".

ala sort of

<v:n><v:Name><v:given-name>George</v:given-name></v:Name> </v:n>

The main problem I see is that  since v:given-name currently has a
restricted cardinality in v:Name, so one could not right now put a
collection of statements there as your example. However, I do agree
that  these complex names are good things and that the parsing rules you
put forward would be necessary to parse these complex names, so we can
(I assume you've noted this) have to get rid of cardinality constraints
currently in the spec.

One question is to keep v:n as a property or make it a class.

Since we currently have a v:Name, I think it's fine to keep v:n as a

 However, I do think that we should get rid of the cardinality
constraints and put in Garret's rules (or something very similar) into
the spec.

What do people think?

+1, but it does make things harder :)
