RDA and LRM Consolidation for Linked Data Implementation
Explore the consolidation of RDA and the IFLA Library Reference Model (LRM) for linked data implementation. Discover how RDA entities refine LRM attributes and relationships to support various database scenarios. Learn about the 4-fold path in linked data and strategic issues for Linked Open Data management.

RDA and the IFLA Library Reference Model (LRM) Gordon Dunsire Chair, RDA Steering Committee Lightning presentation at LD4P / LD4L-Labs Community Input Meeting, Stanford University April 24-25, 2017
LRM and RDA Consolidation and extension of FRBR, FRAD, FRSAD; compatible with CIDOC-CRM All* RDA entities are compatible refinements of LRM * except Person (non-humans excluded) RDA refines LRM attributes and relationships (strings and things) as RDF sub-properties. RDA "4-fold path" extension accommodates strings and things
4-fold path in linked data The 4-fold path supports catalogue cards, flat file schema, RDBMS, and linked data (RDA database implementation scenarios) external property (non-FRBR) unconstrained property (no domain, no range) subPropertyOf "Unstructured description" "Structured description" SES/VES Datatype property (literal range) range canonical property (no range) "Identifier" (local) subPropertyOf Object property (entity range) IRI range
RDA Reference: LD4P frameworks Atomic audit trail Deprecation policy Entities, element sets, value vocabularies Semantic versioning: Application roll-back RDA editors: Secretary Translators Open Metadata Registry RDA/RDF Developers RDA Vocabularies (GitHub) Developers RDA RIMMF3 data editor RDA Toolkit content RDA Registry Vocabulary Server Trainers; Prototypers Developers Applications Cataloguers
Strategic issues for linked open data Identity (IRI) management The "linked" bit Provenance management The "open" bit Otherwise, it's just "data"
