[gutvol-p] RDF Dump: Where is the mapping for Library of Congress information

Hello, I am looking at the new (individual files) RDF dump and trying to understand where some of the subject information is coming from. For example: http://www.gutenberg.org/ebooks/833 has LoC class as "HB: Social sciences: Economic theory, Demography". The RDF in the file is: dcterms:subject rdf:Description http://purl.org/dc/terms/LCC"/> rdf:valueHB So, somewhere "HB" is mapped to the full classification path. But I cannot find that mapping in a parsable form. Is there an authoritative mapping file? Or an algorithm? Regards, Alex.
