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

• • • • 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

• • • 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


• • • • • 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

Early Experimenters

• • • • • British Library Deutsche National Bibliotek DNB George Washington University Library National Library of Medicine Princeton Library

RDA Linked Data MDR Discovery


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
