Is translation type entries omitted in appstream.xml?

I couldn’t find any raw data to analyze, but I found that Flatpak-related appstream.xml data is already present in this location: “/var/lib/flatpak/appstream/flathub/x86_64/(hash)/appstream.xml”.

I checked, and there are only 29 entries related to the <translation type="gettext"> tag.

For example, Collision provides this translation type tag via its metainfo file, see

When I check the tag in the appstream.xml file, I find nothing. It seems the tag is mostly omitted.

The result GNOME Software says Bu uygulama Amerikan İngilizcesinde görünecek (meaning: This app will appear in US English). On the other hand, I’m sure I have translated the app, and it is already Turkish.

The warning banner in GNOME software is shows based on the language tag. Looks like the app has somehow only:

    <languages>
      <lang percentage="100">en_US</lang>
    </languages>

libappstream drops the translation tag when composing.

It seems to have the correct language tags on a local build, so it could be a transient error. I’ve triggered a rebuild to check.
