Steve,
The attribute rdf:resource is just the RDF/XML syntax for specifying the
object of a triple. rdf:resource is itself not a property.
I saw this comment from Ian Green:
I would like to query for resources that have a relationship to some
URI. So for example:
<oslc:resource>
<dc:title>some resource</dc:title>
<acme:relationship rdf:resource="http://cyote.com/res/res1"/>
</oslc:resource>
how would I construct a query to get all resources that have a
<acme:relationship> with a the rdf:resource attribute of
http://cyote.com/res/res1?
we could treat rdf:resource as a special case I guess, but what if the
property was:
<acme:relationship priority="high"
df:resource="http://cyote.com/res/res1"/>
Assume that the acme: prefix is mapped to http://acme.example.org/ns.
Assume the query URL is http://acme.example.org/resource, and its members
are the resources of type <oslc:resource> The query would be:
http://acme.example.org/resource?oslc.prefix=acme=<http://acme.example.org/ns>&oslc.where=acme:relationship=<http://cyote.com/res/res1>
Is this example what you are looking for? If so I'll add it to the spec.
If either URLs contain a '>' character, then it would be escaped as '\>'.

Arthur,
Thanks. It would be helpful to see an example of this in the spec as
well. Specifically, some questions I've heard is how one would reference
@rdf:resource and quoting, etc.
For example, how to query for a specific user URI.
Thanks,
Steve
