  1. The UNIMARC in RDF project: namespaces and linked data Mirna Willer, Gordon Dunsire, Predrag Perožić Presented at Session 222, IFLA WLIC 2013, 22 August 2013, Singapore

  2. The project • Representation of UNIMARC structure and code lists in RDF (Resource Description Framework) • Funded for first year by Permanent UNIMARC Committee • Focus on UNIMARC Bibliographic format • Will take more than 1 year … • Further funding required …

  3. Constructing the element set • “classes and attributes used to describe entities of interest” • W3C Library Linked Data Incubator Group • Represented as RDF classes and properties • In the Open Metadata Registry (OMR) • Uploaded from spread-sheets • Representation at finest level of granularity to avoid loss of information

  7. Value vocabularies • “thesauri, code lists, term lists, classification schemes, subject heading lists, …” • W3C Library Linked Data Incubator Group • Often represented in RDF using Simple Knowledge Organization System (SKOS)
