Mike--

If you have rdf:type properties in your instances, their values should 
be URIs that identify Class resources in your schema.  User-defined 
properties in the instance data should be (after QName resolution) URIs 
that identify Property resources in your schema.  Are you looking for 
some other kind of explicit link?

The Primer isn't silent on the issue.  At least there's an example of 
instance data at the end of Section 5.2 that illustrates the points I 
made above.  Perhaps it could be elaborated (suggestions are welcome, 
although people are always complaining about how long the Primer has 
gotten in trying to follow all the other suggestions.. :-) ..)
