Where is RDA in the bibliographic universe? Gordon Dunsire Presented to Standard RDA – korzyści i problemy związane z jego wdrożeniem = RDA standard – benefits and problems related to its implementation, Warsaw, Poland, 14 October 2016

Where is RDA in the universe of data?

RDA data “RDA is a package of data elements, guidelines, and instructions for creating library and cultural heritage resource metadata that are well-formed according to international models for user-focussed linked data applications.” [RDA Board announcement] RDA Toolkit provides the user-focussed elements, guidelines, and instructions. RDA Registry provides the infrastructure for well-formed, linked, RDA data applications. Open Metadata Registry (OMR) provides linked data representation of RDA elements.

RDA Reference  RDA entities, relationships, designators, vocabulary encoding schemes + translations  Data used in RDA Toolkit Glossary, instructions, and appendices  Also used in other RDA services  Open CC0 license  New content management infrastructure for multiple services and languages

Open Metadata Registry RDA/RDF RDA Vocabularies (GitHub) RDA Toolkit Glossary RDA Registry RIMMF3 RDA editors: Secretary Translators Developers Cataloguers Trainers RDA Vocabulary Server Applications RDA Reference data maintenance and flow

RDA Reference data in Toolkit  Expanded Glossary is a listing of all elements and concepts in RDA Reference  Glossary data is re-used in instructions and appendices  New vocabulary encoding scheme for terminology used by RDA instructions  Many terms included in previous Glossary  Now managed as a separate vocabulary: RDA Terms

RIMMF: RDA in Many Metadata Formats Developed as a training tool and prototype interface for RDA RIMMF3 uses RDA linked data

Legacy data: MARC21 to RDA linked data MARC21 RIMMF RDA RDF linked data MARC21 Semantic Web Legacy systems

Local vocabularies Local terms in RDA vocabularies: Extensions and refinements (narrower/broader, equivalent) Translations! Local vocabularies with similar semantics: Substitutions in local Application Profiles Semantic coherency maintained between OWL object and datatype properties and RDFS properties E.g.: Synonyms, localized terms Ex: Gender

LRM “a high-level conceptual model … intended as a guide or basis on which to elaborate cataloguing rules” FRBR-LRM and RDA RDA guidance, instructions, elements LRM “this model is developed very much with semantic web technologies in mind” RDA linked data communities “operates at a greater level of generality than FRBRoo, which seeks to be comparable in terms of generality with CIDOC CRM” RDA cultural heritage communities

Impact of LRM  More entities (Nomen, Place, Time-span, Agent, Collective Agent)  Shift from attributes to relationships  RDA as a refinement of LRM high-level entities, attributes, and relationships
