AppStream Report for Ubuntu - Issues for git-cola in focal/universe

Warnings

asv-cid-desktopapp-is-not-rdns
git-cola.appdata.xml:3 - git-cola.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-cid-contains-hyphen
git-cola.appdata.xml:3 - git-cola.desktop
The component ID contains a hyphen/minus. 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 (`_`).

git-dag.appdata.xml:4 - git-dag.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.

The component ID contains a hyphen/minus. 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 (`_`).
asv-nonstandard-gnome-extension
git-dag.appdata.xml:5 - metadata
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.
description-from-package
This component gets its description from the package it is located in.
This has several disadvantages, like poor markup, too technical descriptions for users of software centers, different components having the same description, etc.
Please consider writing a metainfo file for this component to take the long description upstream. In future, components without metainfo file might be dropped from the metadata entirely. You can consult the XML quickstart guides for more information on how to write a metainfo file.
