There is already an icon style for ebooks and other fixed document formats, currently in use for "application-pdf" and "application-epub+zip". These consist of a coloured book graphic with a white logo on top (larger resolutions) and a coloured logo-only (smaller resolutions). This style could be expanded to include some commonly used formats that are currently represented as office documents. There could also be a generic icon set for formats that do not have their own design yet. This could be a grey book without a logo (larger resolutions) and a grey book logo (smaller resolutons). Proposed new icons with their own logos and colours: OpenXPS, "application-oxps" - logo: paper aeroplane - colour: light blue DjVu, "image-vnd.djvu+multipage" - see bug https://bugs.kde.org/show_bug.cgi?id=399425 Formats that could use a generic icon (for now): Mobipocket, "application-xmobipocket-ebook" Kindle, "application-vnd.amazon.mobi8-ebook" ComicBook, "application-vnd.comicbook+zip" "application-vnd.comicbook+rar" "application-x-cb7" "application-x-cbt"

There is a precedent for this. For example, "video-x-generic.svg" is a grey filmstrip icon that is used for a number of different video formats. More commonly used video formats reuse the same design but get their own colour. Then there is "application-x-shockwave-flash.svg", which has its own logo on top of the same filmstrip design. The fixed document formats could follow such a three-tier approach, reducing the amount of work required. Including a special a logo for a given format is entirely optional, which is fortunate because a recognizable logo isn't always available. PDF and EPUB are in tier one already. A select few (like DjVu and OpenXPS) could have their own colour and the rest would be links to a generic one.
If you want a new mimetype icon best would be to upload an simple file with the filename of the icon. For example image-vnd.djvu+multipage.djv file will be uploaded so I can test that dolphin use the correct filename.
