Rda future scenarios

RDA: future scenarios

Lars G. Svensson; Gordon Dunsire


Overview

Overview

  • Context

  • Linked data and the Semantic Web

  • RDA triples

  • Role of FRBR

  • Navigating the data

  • What’s in it for whom?


Context

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

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

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

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

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


Other institutions benefit since they can re use library data

Libraries benefit because we don t need to curate all the data ourselves

By involving trusted communities we can maintain high data quality

Open Knowledge Networks

Data generation: registered users and communities, automated algorithms

Quality control: self-control (see Wikipedia)

Sphere

Mantle

Core

Controlled Quality

Data generation: high quality algorithms

Quality control: training and improvement of algorithms

Guaranteed Quality

Data generation an correction: libraries, universities, museums, expert panels, etc.

Quality control: strict rules, panels

Highest stability (persistency)

Byinvolvingtrustedcommunities, wecanmaintainhighdataquality
