I've added some owl:sameAs links to DBpedia as well now:

	e.g. <http://purl.org/NET/book/isbn/9780061474095#book>

My mapping between ISBN numbers and DBpedia resources is here:


It's generated from the DBpedia Ontology ABox data, with ISBNs  
cleaned up and canonicalised.

You may notice that each triple in the mapping file is exactly 128  
characters (as is the prologue of the file) and triples are sorted by  
ISBN in alphabetical order. This allows it to be searched very  
quickly using a binary search algorithm - a little geeky perhaps, but  
I didn't want to slow my ISBN lookup script down by having to grep  
through the entire file (or even parse the entire file as Turtle) for  
each script execution. It also looks pretty.

Ian and Hugh may be interested in using isbn.ttl to map between books  
on DBpedia and ISBN-based URIs for sameas.org.
