description
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)

A Little Background
MAchine Readable Cataloging (MARC) (1967)
A communication format for sharing cataloging via “machines”

Technology has advanced . . .
MARC has not kept pace.
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.
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
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

BIBFRAME Who’s Who

Early Experimenters
13
• How does RDA fit in the proposed model?
• How will specific categories of resources fit in the proposed model, e.g., serials and music?
• How will non-MARC metadata schemes be mapped and encoded?
• What’s missing from the proposed model?
• How does BIBRAME align with Schema.org’s efforts in this same area?
Discussion Papers
• Annotations – (published May 2013)
• Authorities – (published May 2013)
• Relationships • Holdings and Items • Initial Articles and Sorting • Collections/Aggregates (including serials/journals) • Schema.org

Serials in BIBFRAME
15
Serials are messy Can a serial be a bf:Work, “a conceptual cataloging item,” when it’s grounded in time and place?
Should there be a new “Collection” class to collocate collections of bf:Works?
Should “Collection” be a type of bf:Work?
Are supplements new bf:Works?
