RDA: future scenarios

Lars G. Svensson; Gordon Dunsire


Overview

  • Context

  • Linked data and the Semantic Web

  • RDA triples

  • Role of FRBR

  • Navigating the data

  • What’s in it for whom?


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


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”


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)


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

To watch a large graph of linked data can be somewhat intimidating

So who benefits from all this?

Is all this semantic web stuff of any use to me as a library patron?
