As I said before, I don't see it this way. Even though RDF is much  
more flexible than the old record model, it has the concept of  
"subject" -- the subject of the statements, in my mind, defines the  
"about". Library data contains things like author identification as an  
object, but the author is a subject only in the name authority record  
(or foaf Person description set). I really don't see statements about  
authors, publishers, etc. in a library catalog record for a book. All  
of the data there should be with the book as the subject.

In other words, what Jeff said.
