mimetype Mime Type

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

Usage/Remarks

The source for this attribute’s values is the Internet Assigned Numbers Authority (IANA).

Combine @mime-subtype into @mimetype

Modern practice is to avoid using @mime-subtype and @mimetype as separate attributes. Instead, combine mimetype and mime-subtype values, separated by a slash, inside @mimetype (e.g., @mimetype="application/excel"). IANA documentation refers to these combined mimetypes as “media-type”s.
Prior to JATS version 1.4d1 and BITS version 2.1 BITS, the mimetype and subtype attributes were coded separately (mimetype="application" mime-subtype="excel"). For backwards compatibility, this usage will still be valid JATS/BITS, although precombined mimetypes are now preferred.

Best Practice for Media Element Usage

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 mimetype/mime-subtype combination 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.
