  1. RDA: future scenarios Lars G. Svensson; Gordon Dunsire

  2. Overview • Context • Linked data and the Semantic Web • RDA triples • Role of FRBR • Navigating the data • What’s in it for whom?

  3. Context • RDA test executive summary: • Announce completion of the Registered RDA Element Sets and Vocabularies. Ensure the registry is well described and in synchronization with RDA rules. • Business case: ... enables the descriptive metadata created to be used in a linked data world • Demonstrate credible progress towards a replacement for MARC. • LoC Bibliographic Framework Transition Initiative • Experiment with Semantic Web and linked data technologies

  4. Linked data world • Not a new world for bibliographic metadata • Modern library systems link descriptive metadata to authority headings for resource discovery • RDA database scenario 2 • Semantic Web offers opportunities to go global • World-Wide, international scale of the machine-processing infrastructure of the Web • Resource Description Framework (RDF) • Interoperable, simple, atomic metadata statements in the form of “triples”

  5. What does an RDA triple look like? Linked data! . ex:123 rda1:contentTypeExpression rdact:1016 The specified expression has content type tactile notated music taktile Musik content type “taktileMusik” preferred label (de) “tactile notated music” preferred label (en)

  6. Where is FRBR? “Expresión” is-a frbrer:C1002 label (sp) ex:123 ex:345 realization of is-a frbrer:C1003 content type label (en) rdact:1016 “Work” E.g. “content type” specified to have domain (first part of triple) of frbrer:C1002 (Expression) We can register properties like “content type” to say that the first and/or last parts of a triple are specific instances of a particular class
