Format

Format

The physical or digital manifestation of the resource. Typically, Format may include the media-type or dimensions of the resource. Format may be used to determine 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).

Based on best practice, the IANA registered list of Internet Media Types (MIME types) is used to select a term from. For the full list see the scheme location below. Below will follow an example list of IANA MIME types:

If one specific resource (an instance of scientific output) has more than one physical formats (e.g. postscript and pdf) stored as different object files, all formats are mentioned in the DC element 'format', for example:

<dc:format>application/pdf</dc:format>
<dc:format>application/postscript</dc:format>
<dc:format>application/vnd.oasis.opendocument.text</dc:format> 

• Type
