(21 Aug 2024) OCLC is unlocking the power of the Dewey Decimal Classification system to build an increasingly robust linked data infrastructure by creating uniform resource identifiers (URIs) for Dewey numbers.
As the foundation for “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.
Using machine-actionable and web-friendly URIs, Dewey linked data connects across established classifications and subject headings data, such as Faceted Application of Subject Terminology (FAST) linked data. The OCLC Research team helped map Dewey classifications to FAST topical headings and added these relationships to the 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.
