BIBFRAME

Abstract: This article provides a representative overview of literature related to the idea of replacing MARC with a linked-data metadata structure, covering the period from 2002 through the 2012 release of the draft of the proposed bibliographic framework, BIBFRAME. Works proposing the replacement of MARC or exploring linked data in a library context are examined. In particular, key documents leading to the creation of the Library of Congress Bibliographic Framework Transition Initiative are examined, along with some of the critical responses they received, to better understand the chain of ideas shaping BIBFRAME.

Abstract: The ideas behind Linked Data and the Semantic Web have recently gained ground and shown the potential to redefine the world of the web. Linked Data could conceivably create a huge database out of the internet, linked by relationships understandable by both humans and machines. The benefits of Linked Data to libraries and their users are potentially great, but so are the many challenges to its implementation. The BIBFRAME Initiative provides the possible framework that will link library resources with the web, bringing them out of their information silos and making them accessible to all users.

Abstract: 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.

Abstract: By way of a case study this paper illustrates and evaluates the Bibliographic Framework (or BIBFRAME) as means for harvesting and sharing bibliographic metadata over the Web for libraries. BIBFRAME is an emerging framework developed by the Library of Congress for bibliographic description based on Linked Data. Much like Semantic Web, the goal of Linked Data is to make Web “data aware” and transform the existing Web of documents into a Web of data. Linked Data leverages the existing Web infrastructure and allows linking and sharing of structured data for human and machine consumption. The BIBFRAME model attempts to contextualize the Linked Data technology for libraries. Library applications and systems contain high-quality structured metadata but this data is generally static in its presentation and seldom integrated with other internal metadata sources or linked to external Web resources. With BIBFRAME existing disparate library metadata sources such as catalogs and digital collections can be harvested and integrated over the Web. In addition, bibliographic data enriched with Linked Data could offer richer navigational control and access points for users. With Linked Data principles, metadata from libraries could also become harvestable by search engines, transforming dormant catalogs and digital collections into active knowledge repositories. Thus experimenting with Linked Data using existing bibliographic metadata holds the potential to empower libraries to harness the reach of commercial search engines to continuously discover, navigate, and obtain new domain specific knowledge resources on the basis of their verified metadata. The initial part of the paper introduces BIBFRAME and discusses Linked Data in the context of libraries. The final part of this paper outlines a step-by-step process for implementing BIBFRAME with existing library metadata.
