The Dublin Core metadata standards were created by a group of international professionals from several fields. The frequently used Dublin Core Metadata Element Set (DCMES) has 15 terms: title, creator, subject, description, language, date, publisher, contributor, type, format, identifier, source, relation, coverage, and rights. The name space these terms are commonly associated with is http://purl.org/dc/elements/1.1/.
Dublin Core is often used to describe details of ontology authorship, such as in the OWL example below (with dc representing the Dublin Core namespace):
<owl:Ontology rdf:about=""> <dc:title>Simple Snake Robot Ontology</dc:title> <dc:creator>iris</dc:creator> <dc:date>2006-05-03</dc:date> <dc:description>An example ontology of snake robots for http://ci-team.cs.drexel.edu/semantic/ </dc:description> <dc:language>en</dc:language>
This code gives its ontology a title, creator, date, description, and language attribute.
