mimetype Mime Type

Mime type for a graphic, multimedia object, or piece of supplementary material.


Best Practice

The source for this attribute’s values is the Internet Assigned Numbers Authority (IANA). This attribute should be required when creating new books or book parts.

Best Practice

Although this Tag Set cannot enforce it, the element <graphic> should be limited to still images. The element <media> should be reserved for objects whose @mime-subtype involves video, audio, moving images, time-dependent graphic types, and other non-XML data types. Mimetypes and subtypes should be set accordingly but are not constrained by this Tag Set.
