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

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

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
▫ [email protected]
• 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
