Invalid AppStream Appdata

Thanks for shipping AppStream Appdata. However, it fails validation by the AppStream CLI tool version: 0.9.4 (the one in Ubuntu 16.04):

E - itch.appdata.xml:itch.desktop
    Unknown type '(null)' for <translation/> tag.

W - itch.appdata.xml:itch.desktop
    Found invalid tag: 'languages'. Non-standard tags must be prefixed with "x-".

W - itch.appdata.xml:itch.desktop
    Found empty 'translation' tag.

E - itch.appdata.xml:itch.desktop
    'translation' tag has no 'type' property: 

Validation failed.
Failed to validate AppStream information with appstreamcli

Correct! So there’s no way to list the languages in which the app is translated, since there’s no separate -i18n package?

No - the AppStream metadata extractor will determine the l10n status from the translation domain referenced by the <translation/> tag. Additionally, I allowed the <languages/> tag for arbitrary components now, feel free to use it (and maybe use a newer validator to validate).

I’m willing to do that (although io.itch.itch sounds kinda silly), but you might want to fix the Quickstart guide so that its example includes a reverse-domain-name id (instead of gnome-power-manager). I’m now seeing the note, but it’s easy to miss!

Good catch! I thought I converted all of these entries, looks like I missed quite a few.

Thanks for the help so far, I’ll take another pass at it eventually. Is there an up-to-date “single HTML page” or PDF version of this? https://www.freedesktop.org/software/appstream/docs/index.html

No, but we could build one if there is interest in one (it’s all Docbook afterall).

Closing since we don’t ship an official .deb package anymore as of itch v25.
