Specify media types for External Content

A media type is a standard two-part string analogous to a MIME type that identifies external content file types and their format. The media type is used to identify external content and the type of app required to display media during runtime.

A media type consists of a type and a subtype, which is further structured into a tree.

type "/" [tree "."] subtype ["+" suffix] *[";" parameter]

For more information about the format of media types, see https://www.iana.org/assignments/media-types/media-types.xhtml

System Platform provides a default text/html media type that includes an associated app to display web content.

The drop-down list of the Media Type field shows media types in bold text to indicate a viewer app is available in the Galaxy that can service external content with these media types. Other listed media types that appear in plain text require an app to be created and imported into a Galaxy to play the specified media.
