English abstract

RDA elements and terminologies are represented in RDF namespaces managed within the Open Metadata Registry. RDA is based on the conceptual models Functional Requirements for Bibliographic Records (FRBR) and Functional Requirements for Authority Data (FRAD), and RDA elements are constrained to the entities of Work, Expression, Manifestation, Item, Person, Family, and Corporate Body by declaring domains for properties based on attributes and domains and ranges for properties based on relationships, and by making specific references to the entities in the property definitions. These properties are intended for use in RDA and other applications based on FRBR. For non-FRBR applications using, for example, MARC 21 and UNIMARC encoded data, RDA provides a set of properties that are not constrained, with no declared domains or ranges and with generalized definitions. Each constrained or FRBRized RDA property is a sub-property of a non-FRBRized unconstrained property. This improves the interoperability of data from RDA applications by using a simple inference rule to generate new linked data compatible with non-FRBR applications. RDA properties and value vocabularies can also be mapped to properties and terms from other schema to improve the linking of data. The paper describes this approach to linked data interoperability and discusses the issues it raises, including the synchronization of different versions of RDA elements and of RDA with other schema, explicit and implicit mappings between elements, dumbing-down and loss of information, refinement of RDA elements, and the future development of RDA. The paper uses real examples from RDA, Dublin Core, International Standard Bibliographic Description, MARC 21, and UNIMARC.
