Dublin Core Definition: The file format, physical medium, or dimensions of the resource.  Examples of dimensions include size and duration.  Recommended best practice is to use a controlled vocabulary such as the list of Internet Media Types [MIME].
UA Definition: The file format of the digital object.
Usage:

This element should describe the object attached to the record (the access file), not the archival master file.  Record only terms from the Internet Media Types [MIME] controlled vocabulary list (http://www.iana.org/assignments/media-types/media-types.xhtml).  Terms for common formats are listed in the chart below.

For compound objects (resources consisting of multiple formats such as an audio file and text transcript), assign a term for each format.  Enter multiple terms in the same field, separated by a semicolon and a space.  List the most prominent format first.

If dealing with a new format that has not yet appeared on the official list, follow the MIME convention of using an approved object category for the first half of the MIME type (image, audio, application, video, etc.) and the file extension of the new format for the second half.

When it is deemed important to record details about the original physical object, use the optional Extent and Medium elements.

Examples:

image/jpeg

application/pdf

audio/mp3
