RDA in a linked data world Gordon Dunsire Presented at CILIP RDA: Resource Description and Access Executive Briefing 2014, 12 June 2014, London

Overview v. Linked data 101 v. RDA entities and relationships v. RDA and linked data

Linked data Of interest to Libraries Archives Museums Item is links 2 specific things purchased owned autographed donated borrowed conserved photocopied Of interest to Publishers Booksellers by Person Of interest to The Crowd The Cloud Semantic Web

Linked data goes both ways Entity relationship Person purchaser owner autographer donor borrower conserver photocopier is Entity of Item

Linked data needs identities Which person? “Jane Smith, the author of ‘Paper’, OUP, 2001” Person is “Smith, Jane, 1975 -” {URI} Uniform Resource Identifier Global purchaser owner autographer donor borrower conserver photocopier {URI} Which item? “The one in the Reference section” of Item “ 0123 -456 -789” {URI} For humans For machines

RDA entities v. Based on modern international models v. Work, Expression, Manifestation, Item, Person, Corporate Body (FRBR) v. Family (FRAD) v. Work-Expression-Manifestation-Item are discrete components of a resource. This avoids duplication of data v. E. g. Work creator and Expression language are linked to, not copied in, multiple Manifestation descriptions such as a printed book and e-book

One and only one Distinct FRBR/FRAD Entities Work Person Expression Family Manifestation One or more Agent Corporate Body Item Primary/high-level relationships
