This plugin is designed for libraries, archives, and museums that desire a full complement of all Dublin Core metadata fields. Most individuals will not need this plugin.

Once installed, the Dublin Core Extended plugin adds the full set of Dublin Core properties to the existing Dublin Core element set, including element refinements and supplemental elements. See the Dublin Core website, under “Properties in the /terms/ namespace.”

The dc-rdf Output Format

The plugin also introduces the dc-rdf output format for expressing Dublin Core metadata using the Resource Description Framework. Omeka already comes with the dcmes-xml output format, which dc-rdf supersedes. To view this output, simply add “?output=dc-rdf” to the end of the URL on the items browse and show pages.
