asv-cid-desktopapp-is-not-rdns
opentyrian.appdata.xml:3 - opentyrian.desktop
The component ID is not a reverse domain-name. Please update the ID to avoid future issues and be compatible with all AppStream implementations. You may also consider to update the name of the accompanying .desktop file to follow the latest version of the Desktop-Entry specification and use a rDNS name for it as well. In any case, do not forget to mention the new desktop-entry in a <launchable/> tag for this component to keep the application launchable from software centers and the .desktop file data associated with the metainfo data.

asv-developer-name-tag-deprecated

The toplevel `developer_name` element is deprecated. Please use the `name` element in a `developer` block instead.

opentyrian.appdata.xml:10 - OpenTyrian is an open-source port of the DOS game Tyrian.
The first `description/p` paragraph of this component might be too short (< 80 characters). Please consider starting with a longer paragraph to improve how the description looks like in software centers and to provide more detailed information on this component immediately in the first paragraph.
asv-desktop-app-launchable-omitted
opentyrian.appdata.xml -
This `desktop-application` component has no `desktop-id` launchable tag, however it contains all the necessary information to display the application. The omission of the launchable entry means that this application can not be launched directly from installers or software centers. If this is intended, this information can be ignored, otherwise it is strongly recommended to add a launchable tag as well.
asv-developer-info-missing
opentyrian.appdata.xml -
This component contains no `developer` element with information about its author.
