I don't quite understand. According to my information, AppData aside, there must be a .desktop file (for the application) and an .xml file for the mime type. %{_datadir}/applications/myapp.desktop %{_datadir}/mime/packages/myapp.xml The icons %{_datadir}pixmaps/myapp.png %{_datadir}/icons/hicolor/256x256/mimetypes/x-myapp-doc.png The tool desktop-file-install installs the .desktop file into the appropriate location, but there is nothing documented for the mimetype and icons. _______________________________________________ packaging mailing list -- packaging@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to packaging-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/packaging@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
