Karl, I do not understand the question! There is no such thing as
precedences for triples...

*If* the <title> element was to generate a triple (put aside for a
moment that it should not be dc:title, as others have already put it),
it would create a third triple

<> dc:title "The Old Man And The Sea - Literature"

and all three elements would happily live side-by-side. Where would
there be any precedence here?
