Hi there,
In my quest of statistics, I created a script to have numbers about Fedora translation of RPM available in Fedora, based on AppData/AppStream files.
The script is available : https://fedoraproject.org/wiki/User:Jibecfed/read_appdata_fedora_stats To run it, you need to download "Fedora-23.xml" from https://alt.fedoraproject.org/pub/alt/screenshots/f23/
You can donwload examples of output files : * Global statistics https://fedoraproject.org/wiki/File:Output_file_global-2015-11-28.csv * Detailed statistics for French : https://fedoraproject.org/wiki/File:Output_file_fr-2015-11-28.csv
The xml source file is generated every couple of days by Richard Hughes from fedora repositories. His source code is available in https://github.com/hughsie/appstream-glib/
Sincerely,
