RDF Dublin Core Metadata Initiative
The Dublin Core Metadata Initiative (DCMI) has created a number of predefined properties for describing documents.

RDF is metadata (data about data). RDF is used to describe information resources.
Dublin Core is a set of predefined properties for describing documents.
