It may be not the Fedora's way to do it. It's more a Freedesktop thing. I can't recall if you have to update de mime database and/or icon cache (update-mime-database from shared-mime-info package, gtk-update-icon- cache from the package with the same name), or those where used just with the .desktop files. Anyway, those are my two cents. - Iago -

From xdg-mime man page. install Adds the file type descriptions provided in mimetypes-file to the desktop environment. mimetypes-file must be a XML file that follows the freedesktop.org Shared MIME-info Database specification and that has a mime-info element as its document root. For each new file type one or more icons with name type-subtype must be installed with the xdg-icon-resource command in the mimetypes context. For example the filetype application/vnd.oasis.opendocument.text requires an icon named application-vnd.oasis.opendocument.text to be installed So looks like if your mime.xml file have the mime type: application/nice.file You got to install with xdg-icon-resource an icon named: application-nice.file xdg-icon-resource install --novendor --size 48 application-nice- file.png application-nice.file But as you said, it seems there is nothing about it on the guidelines. Sorry for disrupting this thread. It was not my intention.
