I never could get RDF::Simple to work. Don't know what the problem is, but if anyone else is messing around wih OpenCalais I recommend using the JSON output format. If you call it with outputFormat application/json you can do

use JSON;
open(IN,"calaisresultsjson.txt");
my $buffer;
while(<IN>) {
    $buffer .= $_;
}
close IN;
my $json = from_json($buffer);

and you get everything back in a nice keyed hash, no muss no fuss.

If I had written my query better, maybe some monk would have told me that and saved me several hours of frustration. :-/
