Common Ground: Exploring Compatibilities Between the Linked Data Models of the Library of Congress and OCLC
Description: Since 2011, OCLC researchers have been experimenting with Schema.org as a vehicle for exposing library metadata to Web search engines in a format they seek and understand. Schema.org is sponsored by Bing, Google, Yahoo! and Yandex as a common vocabulary for creating structured data markup on Web pages. OCLC’s experiments led to the 2012 publication of Schema.org metadata elements expressed as linked data on 300 million catalog records accessible from WorldCat.org.1 In 2011, BIBFRAME was launched by the Library of Congress (LC) as an initiative to develop a linked data alternative to MARC, building on the Library’s experience providing linked data access to its authority files. In the past year and a half, OCLC has focused on the tasks related to the use of Schema.org: refining the technical infrastructure and data architecture for at-scale publication of linked data for library resources in the broader Web, and investigating the promise of Schema.org as a common ground between the language of the information-seeking public and professional stewards of bibliographic description. BIBFRAME has focused on publishing additional vocabulary and facilitating implementation and testing. These new developments prompt the need to re-examine the relationship between the LC and OCLC models for library linked data. This document is an executive summary of a more detailed technical analysis that will be released later this year.
