Dublin Core (DC)

Dublin Core is a metadata element set created to provide a fundamental body of elements that can be shared across disciplines or within any type of organisation needing
to organise and classify information. The “core” consists of a set of property types and values that provide semantic information about the nature and content of
web resources, much the same way a library card catalogue provides indexes of book properties. In technical terms, Dublin Core is a simple standardised metadata element set, using XML and RDF for crossdomain information resource description. See also: Metadata
