Dublin Core contains 15 classical metadata elements for better cataloguing. These classic elements are called the Dublin Core Metadata Element Set. These classical metadata elements include:

• Creator – The creator of the object
• Subject – The topic of the object
• Title – The name of the object
• Publisher – Details about the person who published the object
• Description – Short description of the object
• Date – The date of publishing
• Contributor – Those who have edited the object
• Identifier – The identifying agent for the object
• Type – Type of the object
• Format – The design and arrangement format of the object
• Relation – Relation with any other object/objects
• Language – The language of the object
• Rights – Any kind of copyright information
• Coverage – Where is the object in the real world

There are two types of Dublin Cores: Simple Dublin Core and Qualified Dublin Core. The Simple Dublin Core is for simple pairs of attribute-values and uses the 15 classic elements, while Qualified Dublin Core uses three more elements for better definition of the data.
