No, but these classification systems are in general thesauri, as opposed to
ontologies, i.e., basically a taxonomy with broader_than/narrower_than
relations only. (01)
The Library of Congress linked data service is at http://id.loc.gov/. With the
SKOS subject headings (among others) at: http://id.loc.gov/download/. But most
are large: e.g.,
http://id.loc.gov/static/data/authoritiessubjects.rdfxml.skos.zip is about 63
MB zipped. The raw rdf is about 1.6 GB. Guaranteed to crash your non-text tool
in general (it does open in WordPad, but blows NotePad, probably would open in
Emacs). (02)
Thanks,
Leo (03)
