UNIMARC Strategic Programme

Permanent UNIMARC Committee


Unleashing UNIMARC to the Semantic Web:

WORKSHOP | 6 abr. '16 | 14h30 - 16h30 | Auditório BNP | Entrada livre

The workshop will first give a basic introduction to the concept of linked data and the W3C standard RDF (Resource Description Framework), the underlying technology of the Semantic Web or Web of Data. Methodology for representing standards in RDF will be described using UNIMARC Bibliographic format as an example, based on work funded by the Permanent UNIMARC Committee in 2013, and IFLA project funds for 2014 and 2015. The content management system for publishing the UNIMARC linked data vocabularies will be presented – OMR: Open Metadata Registry.

In the second part of the workshop, linked data examples using the UNIMARC vocabularies will be presented, illustrating issues in the use of coded data in fixed fields, and publishing linked data from bibliographic systems implementing UNIMARC formats.

The third part of the workshop will focus on future research and plans for development: (1) filling the gaps between tags and subfields, specifically resolving issues of representing repeatable subfields, order of elements, parallel data elements, and the Application Profile; (2) representing UNIMARC authorities in RDF; (3) the semantic alignment of UNIMARC with ISBD; and (4) BIBFRAME (MARC21 in RDF) and UNIMARC: differences in approaches to representing data storage and exchange formats.
