Namespaces for the consolidated edition of the International Standard Bibliographic Description (ISBD) have been published in Resource Description Framework (RDF), the basis of the Semantic Web. The namespaces can be accessed at http://iflastandards.info/ns/isbd/.
The ISBD element set vocabulary includes RDF classes and properties corresponding to ISBD elements. Six concept vocabularies give the controlled terminologies of the ISBD area 0 content forms, qualifications, and media types. Each class, concept, and property has a Uniform Resource Identifier (URI) for use in Semantic Web data triples.
A full de-referencing service is available for each URI. When used in an ordinary Web browser, the URI displays HTML pages with human-readable information about the element or concept. When used in a semantic browser, the URI retrieves machine-readable information in RDF/XML format. It is also possible to retrieve this format using an ordinary Web browser.
For example, the URI for the ISBD content form “music” is http://iflastandards.info/ns/isbd/terms/contentform/T1004. To retrieve the RDF/XML information in a normal Web browser, use http://iflastandards.info/ns/isbd/terms/contentform/T1004.rdf.
The concept vocabularies contain Croatian and Spanish translations of the preferred terms, and the element set vocabulary contains Spanish translations of element labels, definitions, and scope notes. The ISBD Review Group expects to add translations in other languages in due course.
The ISBD namespaces are maintained and accessed using the Open Metadata Registry (http://metadataregistry.org/).
