RDA Linked Data Overview and Implementation Scenarios
Explore the world of RDA linked data as presented by Gordon Dunsire at the RDA Linked Data Forum. This presentation delves into shortcuts, data inheritance, element hierarchies, and new toolkit features. Discover how data is automatically inherited up a hierarchy and the significance of semantic inferencing in RDA data processing.

Short-cuts An element/property that represents a linked chain of two or more other elements has work manifested Work Manifestation Expression has expression manifested has work expressed Expression not recorded The only short-cut in the original Toolkit 4 RDA Linked Data Forum ALA 2019 April 4, 2025
New short-cuts New Toolkit short-cuts simplify aggregates has contributor agent to aggregate Agent Manifestation Expression has expression manifested has creator agent of expression Aggregated expression not recorded 5 RDA Linked Data Forum ALA 2019 April 4, 2025
Element hierarchies All elements belong to a well-defined and well- formed semantic hierarchy 13 x 13 high-level relationship matrix 13 entities linked to 13 entities Full matrix hierarchy under construction Semantics support smart machine-processing of RDA data 6 RDA Linked Data Forum ALA 2019 April 4, 2025

Appellation inheritance Person appellation of person > name of person >> preferred name of person appellation of person > access point for person >> authorized access point for person Dunsire, Gordon appellation of person > identifier for person Gordon Dunsire Gordon Dunsire Gordon Dunsire Dunsire, Gordon Dunsire, Gordon nb2001072552 nb2001072552 8 RDA Linked Data Forum ALA 2019 April 4, 2025
Database implementation scenarios 0: Linked data (RDF) 1: Relational Review and re-cast in light of new RDA Toolkit 2: Bib/authority 3: Flat file 9 RDA Linked Data Forum ALA 2019 April 4, 2025
Scenario: Linked data Discrete entities (and vocabularies) linked by IRI nomen place agent work expression timespan item manifestation 10 RDA Linked Data Forum ALA 2019 April 4, 2025
Scenario: Relational data Discrete entities linked by (local) identifier nomen agent place work expression timespan item manifestation 11 RDA Linked Data Forum ALA 2019 April 4, 2025
Scenario: Bib/authority Compound entities linked by authorized access point agent nomen work expression manifestation Item nomen place nomen timespan nomen 12 RDA Linked Data Forum ALA 2019 April 4, 2025
Scenario: Flat file Compound entities with no links agent nomen work expression manifestation item nomen agent place timespan 13 RDA Linked Data Forum ALA 2019 April 4, 2025
