Dewey Decimal Classifications Now Available as LinkedData – Dewey.info

Michael Danzer reports that a new dataset has been added to dewey.info.

Michael Danzer reports that a new dataset 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).”

He continues, “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. This recent addition massively expands the data set by over 38.000 Dewey classes (or, for the linked data geeks out there, by over 1 million triples), increasing the number of classes available almost tenfold. If you like, take some time to explore the hierarchies; you might be surprised to find numbers for Maya calendar or transits of Venus (loyal blog readers will recognize these numbers).”
