RDA and Linked Data
Steve Henry University of Maryland March 2, 2013
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…
Beethoven, Ludwig van, 1770-1827. Symphonies, no. 1, op. 21, C major has composer Beethoven, Ludwig van, 1770-1827

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
Source: http://bibframe.org/vocab/
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
• • • • • May 2011: Initiative announced May 2012. Zepheira contracted Fall 2012. Use cases tested November 2012. Bibliographic Framework as a Web of Data (high-level model) October and December 2012. Face-to-face meetings with early experimenters

RDA Linked Data MDR Discovery
BIBFRAME
Rule of Three
Attributes for Persons
Medium of Performance
• • • • Talk to vendors ▫ Show them MDR ▫ Ask them what their plans are for L.D.
Follow BIBFRAME development ▫ Bibframe.org
Look for RDA records in your discovery tools ▫ Think about search strategies ▫ Ask a cataloger for help!
Link your data ▫ Discographies, bibliographies, thematic catalogs ▫ Digital Humanities projects
