Enhanced level description:
- Indicates that the basic resource has been supplemented by assignment of some metadata
- May not explicitly indicate the content standards used nor is there any commitment to authority control of access points. Note: The absence of clear identification of content standards means the NBA cannot be certain of the consequences to the users
- Is not recommended for use in national bibliographies and should be upgraded over time if it is to be incorporated into the national bibliography
- Does not adequately support resource discovery tasks
Examples of enhanced metadata which could be re-used by the NBA include unqualified Dublin Core and TEI headers.
