Dublin Core

Dublin Core is a schema with a relatively small set of terms that can be used to describe digital as well as physical resources.

The Dublin Core standard previously included two levels, Simple and Qualified. Simple Dublin Core included 15 elements, while Qualified Dublin Core included three additional elements, as well as a element refinements/qualifiers.

In 2012, Simple and Qualified Dublin Core were merged into a single set of terms using the RDF data model. These are the DCMI Metadata terms listed below.
