  1. From content standards to RDF Gordon Dunsire Presented at AKM 15, Porec, 2011

  2. Content standards • Instructions/rules on creating and maintaining the content of bibliographic metadata (records) • Aim to improve consistency, coherency, and completeness of records • For resource discovery services • Different standards for different domains (archives, libraries, museums) • And different contexts and changes over time • E.g. International Standard Bibliographic Description (ISBD), Anglo-American Cataloguing Rules (AACR), RDA: resource description and access ...

  3. Example: ISBD consolidated edition 2011 The place of publication, production and/or distribution is the name of the place associated on the prescribed source of information with the name of the publisher, producer or distributor. Element Relationship Content source Definition

  4. Example: RDA toolkit 2011 Record the type of carrier used to convey the content of the resource using one or more of the terms listed below Element Content source Definition

  5. Components & framework Definition Domain model (Abstraction) Element Description set profile (Machine interpretation) Relationship Usage (Human interpretation) Usage guidelines Content source

  6. DCMI Singapore framework DCMI syntax guidelines Syntax guidelines and data formats Local RDF schema Metadata vocabularies Description set profile Usage guidelines DCMI abstract model RDF Community domain models Domain model Application profile Global Functional requirements

  7. Application profile “Record” structure Elements: Mandatory? Repeatable? Sequence? Aggregation? Everything expressed in Resource Description Framework (RDF) [real soon now: ISBD/DCMI collaboration]

  8. RDF triple Subject : Predicate (property) : Object URI : URI : URI (Linked data!)/Literal (Display) Metadata content: This book (URI) : Has author (URI) : That author (URI) Element semantics: Has author (URI) : Has definition (URI) : “Relates …”

  9. RDF graph Property1 URI Subject URI Object URI Object literal Property2 URI

  10. Application (profile) semantics: has minimum occurrence (URI) “1” = mandatory, non-repeatable Has title (URI) “1” has maximum occurrence (URI)  Record content: “Museum archives” has title (URI) This book (URI) has creator (URI) Author1 (URI) Author2 (URI) has contributor (URI)

  11. Linking data from different domains = linking data from different graphs is same as (URI) is same as (URI) Author1 (URI) AuthorX (URI)
