Flathub requires a developer tag and developer ID. Also Appstream decided to use rdns structure for developer ID.
It allows reverse-dns IDs like sh.cozy, de.geigi or Fediverse handle (like @user@example.org)
A developer tag with a name child tag must be present.
Only one developer tag is allowed and the name tag also must be present only once in untranslated form.
The element should have a id property, containing a unique ID to identify the component developer / development team. It is recommended to use a reverse-DNS name, like org.gnome or io.github.ximion, or a Fediverse handle (like @user@example.org) as ID to achieve a higher chance of uniqueness.
appdata: Mark release descriptions as untranslatable
GNOME automatically excludes release descriptions on Damned Lies (GNOME Translation Platform). It's a good practice to follow the GNOME way.
This can streamline the translation process, allowing translators to focus their efforts on more critical and user-facing aspects of the application.
