<p class="MsoNormal">OCLC is committed to its <a href="https://www.oclc.org/en/linked-data.html" target="_blank">
linked data strategy</a>, and we continue to publish existing library information as linked data in ways that support better description and discovery of library resources across the web. We’ve already made fundamental steps forward in building a linked data
ecosystem with the release of <a href="https://www.oclc.org/en/meridian.html" target="_blank">
OCLC Meridian</a> and <a href="https://entities.oclc.org/worldcat/entity" target="_blank">
WorldCat Entities.</a> And now, we’re pleased to announce the transformation of another dataset: the Dewey Decimal Classification (DDC) system. <o:p></o:p></p>
<p class="MsoNormal"><b>Unlocking the power of Dewey</b> <o:p></o:p></p>
<p class="MsoNormal">We’re 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 our “concept” entities, this Dewey linked data provides
subject classifications to Works entities in<span style="font-family:"Arial",sans-serif"> </span><a href="https://www.oclc.org/en/news/releases/2022/20220524-oclc-releases-worldcat-entities.html">WorldCat Entities</a>, creating a layer of new relationships
for knowledge graphs that power discovery. <o:p></o:p></p>
<p class="MsoNormal">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. <o:p></o:p></p>
<p class="MsoNormal"><b>Who can access Dewey linked data?</b> <o:p></o:p></p>
<p class="MsoNormal">Anyone is free to <a href="https://entities.oclc.org/worldcat/ddc">
view and access a base set of Dewey linked data</a> and can begin integrating Dewey URIs into their local data management and discovery systems today.<o:p></o:p></p>
<p class="MsoNormal">Libraries that subscribe to <a href="https://www.oclc.org/en/dewey/webdewey.html">
WebDewey</a> have access to the full range of Dewey linked data URIs and associated metadata. In addition,
<a href="https://www.oclc.org/developer/api/oclc-apis.dewey.en.html">two new APIs</a> 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.
