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> <dcam:memberOf rdf:resource="http://purl.org/dc/terms/LCC"/> <rdf:value>HB</rdf:value> </rdf:Description> </dcterms:subject> 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.
