By Requirement

Mandatory

Elements that must be present and are required for the system to operate, either from a technical or functional need. Records without this metadata cannot be loaded into the system. Note, however, that a majority of mandatory metadata is created at an aggregate level or is system generated.

Preferred

Elements that should be included if it is available; note that some preferred metadata elements are not relevant to some types of records. Preferred metadata greatly increases the usability of the system by providing descriptive information that supports retrieval or selection because it captures the most essential, valuable information about the content.

Desirable

Elements that could be included when available. Use of these elements will vary based on local practice, and the decision to include this information is based on the cataloger’s judgment of its value in the context of a particular series.

Optional

Elements that may be of particular value, but relevant to a limited number of records. Also elements that may be important in the future, but the pilot system will store these elements but will not likely have any functionality based on these elements. Use of these elements will vary based on local practice and the cataloger’s judgment.
