Unlocking the power of Dewey
OCLC is unlocking the power of the DDC to build an increasingly robust linked data infrastructure by creating uniform resource identifiers (URIs) for Dewey numbers. As the foundation for its “concept” entities, this Dewey linked data provides subject classifications to Works entities in WorldCat Entities, creating a layer of new relationships for knowledge graphs that power discovery.
These identifiers make the Dewey classification numbers more meaningful, create connections between broad classification numbers and specific subject topics, and provide multi-language labels for otherwise opaque numbers. Using machine-actionable and web-friendly URIs, Dewey linked data connects across established classifications and subject headings data. For example, the OCLC Research team mapped Dewey classifications to FAST (Faceted Application of Subject Terminology) topical headings, enabling relationships to the Dewey linked data.
Who can access Dewey linked data?
Anyone is free to view and access a base set of Dewey linked data and can begin integrating Dewey URIs into their local data management and discovery systems today.
Libraries that subscribe to WebDewey have access to the full range of Dewey linked data URIs and associated metadata. In addition, two new APIs are available that enable users to easily integrate Dewey linked data into other systems and services. WebDewey users can access these APIs as part of their subscription.
