TRANSCRIPT
Encoding RDA Data
•One more time: RDA is a content standard not a display standard▫It is also not an encoding standard
•Examples so far have shown RDA in a MARC environment
•But RDA is also designed to be flexible.▫Can be encoded in MODS, Dublin Core,
etc….▫…and in RDF
RDF -Resource Description Framework•RDF is a Web standard for describing any
thing, concept, or relationship•Each thing, concept, and relationship is
represented by a globally unique URI•Relationships between these entities are
represented by RDA triples in the form: subject, predicate, object
•For example…

Linked Data
•A set of best practices for ▫Sharing data▫On the Web▫In machine-readable form
•Four rules▫Provide a URI▫Make the URI an HTTP URL▫Provide interesting information▫Link to other URIs so more things can be
discovered

BIBFRAME
•Full name: Bibliographic Framework Transition Initiative
•Initiative of the Library of Congress•Essentially a linked data model for library
bibliographic data•Potential replacement/supplement for
MARC
BIBFRAME
•Each instance gets a URI•Relationships between works, instances,
authorities, places, recorded•Needs to be harmonized with FRBR—
Expressions?▫FRBR seen as an abstract model▫BIBFRAME is a Web implementation
BIBFRAME Timeline

Framework as a Web of Data (high-level model)
