Thomas,
I agree with you on that very last point about "sneaking" universal
quantification. Does not look very clean to me.
However, I just agree with Brian on the main topic : it may be useful in
many cases to *partially* describe a statement. To make an example
similar to Brian's...
<rdf:Description rdf:about="http://champin.net/">
<foo:contains>
<rdf:Statement>
<rdf:predicate rdf:resource="&foo;phoneNumber"/>
<rdf:subject rdf:parseType="Resource">
<vcard:EMAIL rdf:resource="mailto:pa@champin.net"/>
</rdf:subject>
</rdf:Statement>
</foo:contains>
</rdf:Description>
meaning something like
"The page <http://champin.net/> contains the information about the phone
number of the person with e-mail address pa@champin.net"
or more concisely : "You can find my phone number on my homepage"
whatever that phone number is ! It may change, the above RDF is still
valid.
