I'm trying to follow what's happening related to gnome-software and the .appdata.xml files. There is a growing number of mails, but I cannot find any message that points out what the file # rpm -qf /usr/share/app-info/xmls/fedora-20.xml.gz gnome-software-3.10.3-1.fc20.x86_64 does. For "Audacious" it specifies several details, such as an icon included in the gnome-software package and MIME types. How to update or override those details? The file contains a summary "Listen to music". So far, I'm unable to install an AppData file for Audacious that would be recognised by gnome-software. The installed file validates fine. Still, gnome-software only displays "Listen to music". Is there a hidden cache file in some place? Or a remote database that is updated from time to time? I've tried to "Remove" Audacious via gnome-software, then reinstall it, but that didn't fix it either. [1] How to determine why the file is not recognised? What is the recommended procedure to test new .appdata.xml files? Where does gnome-software find those files? I mean, for uninstalled packages the files are not available. Not even the .desktop files. There must be some method that recognises such files in repo metadata and extracts them, or else gnome-software could not know about the file contents. Is a screenshot mandatory? The current test-update for Audacious includes an .appdata.xml file where the screenshot section is commented out. Is that permitted? I've noticed an AppData file has been contributed to Soundconverter upstream. Since the Fedora packages of Soundconverter lead to many changes upstream, I've merged the file, but the specified screenshot does not display. The validator finds a problem: /usr/share/appdata/soundconverter.appdata.xml 1 problems detected: • attribute invalid : <screenshot> width was too small The contributed file does not set any attributes width or height. [1] There's a related bug in gnome-software, btw, since a consecutive Remove and Install does not work. https://bugzilla.redhat.com/1027183 -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
