The metadata standard is an application profile of the Dublin Core Metadata Element Set and consists of mandatory, recommended and optional metadata elements such as title, date created and description.

This was a response to communities whose metadata needs required additional detail. [11] In 2012, the DCMI Metadata Terms was created using a RDF data model. [12] This expanded element set incorporates the original 15 elements and many of the qualifiers of the qualified Dublin Core as RDF properties.
The PRISM specification defines a set of metadata vocabularies. PRISM metadata may be expressed in a different syntax depending on the specific use-case scenario.
