Linked Data

Linked Data is about communities agreeing on the meaning of their data and sharing it in a massively networked information space. This vision is taking shape in many sectors, including e-commerce, medicine, scientific research, and government services. OCLC Research is a leader in driving this transformation in the library community.

Community Discussion & Standards Development

OCLC researchers are committed to the development of library linked data through engagement with standards bodies and community discussion. This work produces reports, white papers, webinars, and proposals. It is also organically connected to our own research projects; see the Linked Data Research page for more detail.

The Program for Cooperative Cataloging
Since 2014, the PCC has addressed many issues involving the transition from MARC to linked data. In June 2017, the Linked Data Advisory Committee (PCC LCAC) issued the report: Strategic Directions, January 2018-December 2021, which states, "It is time to move beyond knowledge and skills related to linked data and into implementation." Three of the six strategic directions identified in the report apply to linked data:

  • apply understanding of linked data;
  • accelerate the movement toward ubiquitous identifier creation and identity managementa at the network level;
  • expand use of linked data vocabularies to augment, and where feasible to replace, existing metadata practices.

OCLC linked data researchers are participating in three PCC task groups that are advancing these priorities:
