Here is the first of your problems. The namespace for rdf is
http://www.w3.org/1999/02/22-rdf-syntax-ns#

If you use http://www.w3.org/TR/RDF/ then all parsers will refuse to
recognize it as RDF. Incidentally, the convention is to use rdf:
rather than r:, though r does work.

This is another error. URIs are case sensitive, so you need to say:
<Topic r:ID="Top">

You can test all of this with the W3C RDF Validator:
