No translation information in appstream

[Will Thompson]

GNOME Software shows a nice badge if the app you're looking at is translated into your language. For Kolibri, it shows that it is not translated into French:

However, Kolibri (both the GNOME app, and Kolibri itself) are very thoroughly translated into French.

GNOME Software uses the data from the AppStream collection data. This is not supposed to be provided by the app. It is generated when the appdata for each app is combined into one giant file for the repo. There is a tag which tells the generator what translation system is in use, and what translation domain to use.

I think it is probably sufficient to specify:

<translation type="gettext">kolibri-gnome</translation>

in the appdata. Of course this will only measure translation of the GNOME app rather than Kolibri itself, but (I would guess?) that the coverage is likely to be similar.
