calibre-gui.appdata.xml:3 - calibre-gui.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.

calibre-gui.appdata.xml:9 - calibre is the one stop solution to all your e-book needs.
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-cid-contains-hyphen
calibre-gui.appdata.xml:3 - calibre-gui.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 (`_`).

description-from-package
This software 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 to either hide this .desktop file from AppStream by adding a X-AppStream-Ignore=true field to its .desktop file, or to write 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.
