Background and Overview: Dewey Summaries as Linked Data via OCLC
For a long time, the Dewey team at OCLC has wanted to do something with Linked Data. That is, apply Linked Data principles to parts of the Dewey Decimal Classification and present the data as a small “terminology service.” The service should respond to regular HTTP requests with either a machine- or a human-readable presentation of Dewey classes. There should be a URI (and, even better, a Web page that delivers a useful description) for every Dewey concept, not just single classes. The data should be presented in a format that is capable of handling rich semantic information and in a way that allows users or user agents to just “follow their nose” to explore the data. For more complex stuff, the service should offer an API-like query access. Finally, the data that is presented should be reusable by anyone for non-commercial purposes.
