Hurrah!

I was looking for linked data URIs for the Dewey Decimal Classification
a few months ago, and while I eventually found <info:ddc/22/eng//641>,
these aren't very "linked data" as they're not dereferencable via HTTP.
So I set up my own, in the format:

	<http://purl.org/NET/decimalised#c470>

The data is available in RDF/XML and N-Triples with a subset in XHTML
+RDFa, all content negotiated. 

I've called my data the "Decimalised Database of Concepts" to reflect
the fact that the information shouldn't be treated as necessarily
exactly the same as official Dewey Decimal Classification concepts.

It includes SKOS "relatedMatch" mappings to DBpedia and "closeMatch"
mappings to LCSH and LCCO in many cases. In light of your announcement
yesterday, I've added "exactMatch" mappings to dewey.info's URIs too.

I don't know if this information or the mappings are any use to you.
It's available under CC-BY-SA, which is not especially compatible with
the CC-BY-NC-ND license used by dewey.info, but given that the vast
majority of my data comes from Wikipedia, I don't really have the choice
of publishing it under a different license.
