The Missing Link-The Evolving Current State of Linked Data for Serials-Fallgren
•

Linked data may hold the potential to solve some classic serials dilemmas like latest vs. successive entry, or single vs. multiple records for print and online. How do these hopes mesh with the evolving current state of linked data projects in the commercial and library sector as well as with LC’s Bibframe initiative? The speakers will provide three different perspectives. An “early experimenter” and member of the Bibframe group modeling serials will discuss her experiences and thoughts on future directions. A publisher from a company that has reorganized some of its infrastructure and processes to facilitate linked data will share the goals and provide examples of the benefits of that project. Finally, the head of the U.S. ISSN Center will take an ISSN perspective as well as compare international work modeling serials according to FRBR-OO (object-oriented) with the Bibframe serials modeling effort. Audience input will be solicited in order to provide an exchange of ideas and viewpoints. (moderated by Laurie Kaplan)

- 4. Cataloging has changed . . . • Resource Description and Access (RDA) (2013) – Focuses on relationships in and among resources – Vocabularies and relationships are being developed in a linked data format – Adjustments to MARC to accommodate RDA renders both standards more complicated and confusing 4 MARC has been left behind.
- 5. Replacing MARC “On the Record” (Working Group on the Future of Bibliographic Control, 2009) – 3.1.1 Develop a More Flexible Extensible Metadata Carrier – 3.1.2 Integrate Library Standards into Web Environment Report and Recommendations of the U.S. RDA Test Coordinating Committee (2011) – Findings: Systems, Metadata, and Technical Feasibility (p. 101) • “ . . . it [MARC] has reached the limit for significant improvement in allowing our data to be widely integrated and used across the information landscape.” • “While one of RDA’s goals is to explicitly express resource relationships, MARC will not allow our systems to easily display and utilize these relationships. . . . MARC may hinder the separation of elements and ability to use URIs in a linked data environment.” 5
- 6. BIBFRAME’s Goals • Flexible/extensible framework for adaptability and longevity – Rule agnostic – Web-based • Leverage linked data model for sharing resource description – Make use of controlled vocabularies and authoritative data sets published as URIs – Make explicit relationships within and among resources at a granular level 6
