Dublin Core Definition: The physical or digital manifestation of the resource.

Dublin Core Comment: Typically, Format may include the media type or the dimensions of the resource. Format may be used to describe the software, hardware, or other equipment needed to display or operate the resource. Examples of dimensions include size and duration. Recommended best practice is to select a value from a controlled vocabulary (for example, the list of Internet Media Types [MIME] defining computer media formats).

The OSU Library will use the Format element to record digital manifestation of the resource and use the Internet Media Type (IMT scheme). 

Use the Extent refinement to record a resource’s file size and/or duration. 

Use the Medium refinement to describe an item’s physical (as opposed to its digital) nature. 

The Format element is reserved for describing the access file only (be it image, audio, or video). Technical metadata relating to the digitization process (i.e., scanner model, scanner resolution, color schemes, file size of the master file, etc.) should be recorded in the Technical Specifications element.

1. Some digital objects may involve more than one format, for example, an oral history interview may have audio formats and text format transcriptions. Use separate Format elements for the refinements Extent and Medium.
2. Enter formats for different purposes as separate Format elements, i.e., separate file size and
   duration entries.
3. Select electronic format terms from the Internet Media Types (IMT) standardized list, formerly
   known as MIME types.
4. Record the file size as kilobytes (Kb), megabytes (Mb), etc. Not bytes.
5. For audio and video file formats include the duration (i.e., play time) of the resource.
   New media types and applications are always emerging. If the resource format being described is
   not yet part of the IMT type list, follow the IMT convention by selecting a broad category of object
   format (audio, video, application, etc.) for the first part of the IMT type, then use as a brief
   identifier for the second half of the IMT type the file name suffix that is usually attached to files of
   this format. See "audio/WAV" example below.
