Hints for wesnoth-1.16-core in ubuntu

org.wesnoth.Wesnoth-1.16.desktop ⚙ amd64

asv-cid-rdns-contains-hyphen
:4 - org.wesnoth.Wesnoth-1.16.desktop
The component ID contains a hyphen/minus in its domain part. Using a hyphen is strongly discouraged to improve interoperability with other tools such as D-Bus. A good option is to replace any hyphens with underscores (`_`). Hyphens are only allowed in the last segment of a component ID.
translations-not-found
Unable to add languages information, even though a translation tag was present in the MetaInfo file. Please check that its value is set correctly, and all locale files are placed in the right directories (e.g. /usr/share/locale/*/LC_MESSAGES/ for Gettext .mo files).

asv-cid-has-number-prefix
:4 - org.wesnoth.Wesnoth-1.16.desktop: 16 → _16
The component ID contains a segment starting with a number. Starting a segment of the reverse-DNS ID with a number is strongly discouraged, to keep interoperability with other tools such as D-Bus. Ideally, prefix these segments with an underscore.
asv-developer-name-tag-deprecated
:92 -
The toplevel `developer_name` element is deprecated. Please use the `name` element in a `developer` block instead.
asv-nonstandard-gnome-extension
:98 - kudos
This tag is a GNOME-specific extension to AppStream and not part of the official specification. Do not expect it to work in all implementations and in all software centers.
