DCMI Metadata expressed in RDF Schema Language
The Resource Description Framework (RDF) is a metadata framework that provides a degree of semantic interoperability among applications that exchange machine-understandable metadata on the Web. RDF Schema is a specification developed and maintained under the auspices of the World Wide Web Consortium. More information is available at http://www.w3.org/TR/rdf-schema/.
In accordance with the DCMI Namespace Policy [NAMESPACE], DCMI identifies metadata terms with Uniform Resource Identifiers (URIs) in the four DCMI namespace URIs listed below. These namespace URIs are redirected by the server http://purl.org to RDF schema files on the server http://dublincore.org.
As of 2006-08-28, DCMI identifies these RDF schemas to browsers as being of type "application/rdf+xml". Not all browsers associate a default action with "application/rdf+xml", so users of some browsers may be offered a choice of actions. DCMI plans to improve this situation by putting into place "conditional redirects" to redirect most users from http://purl.org to the documentational Web page "DCMI Metadata Terms" [TERMS].
As the DCMI vocabularies grow and evolve, the PURL redirects are revised to point to successive updated RDF schemas. All historical changes in DCMI vocabularies are recorded in the document "DCMI Metadata Terms: A complete historical record" [HISTORY] and an up-to-date snapshot of latest versions is maintained in the file "DCMI Metadata Terms" [TERMS].
RDFa representations in reverse-chronological order
The 2012-06-14 release of DCMI Metadata Terms reflects the following changes and improvements:
- embedded RDF representation of DCMI metadata terms using RDF 1.1
- content negotiation to serve RDF/XML, Turtle, or RDFa/HTML representations in response to browser or application requests
- DCMI Type Vocabulary, always a part of the consolidated DCMI Metadata Terms document, is no longer redundantly served as a separate stand-alone document
