As the error says, "15" on the first line of your file is not a legal 
subject value in N3 grammar.

Specifically, these DEBUG statements aren't valid N3.  You should delete 
them or comment them out, or otherwise instruct D2RQ not to output them.

Try validating your RDF as a first step in debugging:

http://www.w3.org/RDF/Validator/

Not all RDF parsers are equal, unfortunately, but you may have the most 
success with parsing compatibility if you use RDF/XML instead of N3.
