OCLC creates Uniform Resource Identifiers for Dewey Decimal Classification Numbers

From OCLC:

OCLC leverages 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, these Dewey-linked data provide thematic classifications for Works entities in WorldCat entities, creating a layer of new relationships for knowledge graphs that facilitate discovery.

“OCLC is committed to our linked data strategy and we continue to publish existing library information as linked data to enable better description and discoverability of library resources across the web,” said Mary Sauer-Games, OCLC Vice President, Global Product Management. “With the release of OCLC Meridian and WorldCat Entities, we have already taken fundamental steps in building a linked data ecosystem and are now pleased to announce the transformation of another dataset: the Dewey Decimal Classification system.”

Using machine-readable and web-friendly URIs, Dewey Linked Data links established classifications and subject heading data such as FAST (Faceted Application of Subject Terminology). The OCLC research team helped map Dewey classifications to FAST subject headings and add these relationships to Dewey Linked Data.

Anyone can view and access a base set of linked Dewey data and 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-associated data URIs and associated metadata. In addition, two new APIs are available that allow users to easily integrate Dewey-associated data with other systems and services. WebDewey users can access these APIs as part of their subscription.
