• Correspond to DTDs, XML schemas, etc
• Elements

• Equivalent to elements in XML or XSD files,
  column in database, field in a webform
• Content can be terms from vocabularies or
  uncontrolled, user specified content.
• Elements conceptually related to each other are
  grouped together into larger conceptual units -
  Content Classes.

• Structured collection of metadata terms to be
  used as content in Elements
• Simple lists or complex hierarchies
• Terms
• Approved metadata value used to tag content
• Individual words or phrases used in Vocabularies
