Dewey as Linked Data

Exciting news from the Dewey weblog, the Dewey Classification is now available as linked data.
As announced on Monday at the seminar "Global Interoperability and Linked Data in Libraries" in beautiful Florence, an exciting new set of linked data has been added to dewey.info. All assignable classes from DDC 23, the current full edition of the Dewey Decimal Classification, have been released as Dewey linked data. As was the case for the Abridged Edition 14 data, we define "assignable" as including every schedule number that is not a span or a centered entry, bracketed or optional, with the hierarchical relationships adjusted accordingly. In short, these are numbers that you find attached to many WorldCat records as standard Dewey numbers (in 082 fields), as additional Dewey numbers (in 083 fields), or as number components (in 085 fields).

The classes are exposed with full number and caption information and semantic relationships expressed in SKOS, which makes the information easily accessible and parsable by a wide variety of semantic web applications.
