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).
In terms of licensing, all data (including DDC 23 classes) are still reusable under the same terms (Creative Commons BY-NC-ND) and the license is carried in each record. Regarding updates, dewey.info is now fully integrated into the standard data flow of the Dewey ecosystem; updates are automatically distributed from the same source that provides data for WebDewey. Going forward, DDC 23 data in dewey.info will be updated regularly.
