In May 2012, the Library of Congress announced a new modeling initiative focused on reflecting the MARC 21 library standard as a Linked Data model for the Web, with an initial model to be proposed by the consulting company Zepheira. The goal of the initiative is to translate the MARC 21 format to a Linked Data model while retaining the richness and benefits of existing data in the historical format.
In this webinar, Eric Miller of Zepheira will report on progress towards this important goal, starting with an analysis of the translation problem and concluding with potential migration scenarios for a broad-based transition from MARC to a new bibliographic framework.

“The Initiative aims to re-envision and, in
the long run, implement a new
bibliographic environment for libraries
that makes "the network" central and
makes interconnectedness commonplace.”

11. Linked Data
"a term used to describe a recommended best
practice for exposing, sharing, and
connecting pieces of data,
information, and knowledge on the Semantic
Web using URIs and RDF."

15. BIBFRAME Design Background
• Deconstructing MARC
• Linked Data“Things not Strings”
• Ground truth of data patterns
• Analysis of existing Linked Data efforts / patterns
• Implementable
• Addresses RDA use cases / scenarios (first
among equals)
• Adheres to Web Architecture
• History / experience

25. What is Bibframe?
• Bibframe is a linked data model for bibliographic data
• Requirements and Goals:
• Inherent the robust nature of the MARC standard
• Be content model agnostic - RDA, DACS, CCO, etc.
• Handle description and management of traditional (books,
serials, etc.) and non-traditional materials (born digital, data
sets)
• Integrate supporting data (Authority, Holdings, Classification)
• Benefits from all the goodness the Web offers (web triggers,
collaboration, data driven, etc.)

badgers Rabo into telling his life story—and Vonnegut in turn
tells us the plain, heart-hammering truth about man’s careless
fancy to create or destroy what he loves.",
