  1. RDA: thinking globally, acting globally Gordon Dunsire Presented at International Developments in Library Linked Data: Think Globally, Act Globally – Part Two: an ALCTS Program, ALA Annual, Las Vegas, USA, 28 Jun 2014

  2. Overview • Failure of top-down approach • RDA tools • Case: intended audience • Mapping the focus of description • Top-down, bottom-up issues

  3. Acting locally Universal Bibliographic Control Thinking globally KOS++ Confusing tongues? RDF FR: Functional Requirements BIBFRAME: Bibliographic Framework ISBD: International Standard Bibliographic Description Say what we mean DC: Dublin Core BibO: Bibliographic Ontology RDA: Resource Description and Access CRM: Conceptual Reference Model MARC21 schema.org UNIMARC

  4. Element set + Relationship designators Links to other vocabularies For unFRBRized applications 30 million (partial) examples

  5. Globalizing RDA linked data Language-specific labels and definitions (for humans) Language-specific URIs (for developers) Language-neutral URIs (immutable)

  6. Map of “Audience” Element sets (schema) Unconstrained versions Value vocabularies (KOS) Broader/narrower/same? rdfs:subPropertyOf “adult” schema: “audience” rdaw: “Intended audience” bf: “Intended audience” m21: “Target audience” frbrer: “has intended audience” isbd: “has note on use or audience” isbdu: “has note on use or audience” dct: “audience” rdau: “Intended audience” “adult” pbcore: adult MPAA: NC-17? umarc: m umarc: k BBFC: 18? m21: e “adult, general” “adult, serious” m21: “Target audience of …”

  7. Mapping entities rda: Work isbd:P1193 (has work aspect ) bf: expressionOf rdae:P20231 (has work expressed) bf: Work isbd:P1190 (has expression aspect ) ? rda: Expression rdam:P30139 (has expression manifested) bf: Instance bf: instanceOf rda: Manifestation isbd:P1192 (has manifestation aspect ) marc21: Resource isbd: Resource rdai:P40049 (has manifestation exemplified) rda: Item isbd:P1191 (has item aspect )

  8. Top-down • Examine local schema • Identify the common elements • Create a common/global element set (RDF) • Refine the global element set to connect down (map) to specific local elements • Issues • Common elements may not cover the same space as local elements • Refinement not possible • Common elements have to be augmented • Favours the global over the local • Encourages a good-enough approach

  9. Bottom-up • Publish the local schema(s) in RDF • Map local elements from different schema to lowest common (dumber) elements – add new elements if necessary • Continue until all local schema have been mapped • Issues • Multiplicity of RDF element sets • Frequent overlap and redundancy • Local management resources
