Hints for pychess in main

pychess.desktop ⚙ all

asv-cid-desktopapp-is-not-rdns
pychess.metainfo.xml:4 - pychess.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-screenshot-no-media
pychess.metainfo.xml:55 -
A screenshot must contain at least one image or video in order to be useful. Please add an <image/> to it.
asv-screenshot-no-media
pychess.metainfo.xml:56 -
A screenshot must contain at least one image or video in order to be useful. Please add an <image/> to it.
asv-screenshot-no-media
pychess.metainfo.xml:57 -
A screenshot must contain at least one image or video in order to be useful. Please add an <image/> to it.

asv-id-tag-has-type
pychess.metainfo.xml:4 - pychess.desktop
The <id/> tag still contains a `type` property, probably from an old conversion to the recent metainfo format.
asv-url-not-secure
pychess.metainfo.xml:59 - http://pychess.github.io
Consider using a secure (HTTPS) URL for this web link.
asv-unknown-tag
pychess.metainfo.xml:60 - updatecontact
Found invalid tag. Non-standard tags should be prefixed with `x-`. AppStream also provides the <custom/> tag to add arbitrary custom data to metainfo files. This tag is read by AppStream libraries and may be useful instead of defining new custom toplevel or `x-`-prefixed tags if you just want to add custom data to a metainfo file.
asv-desktop-app-launchable-omitted
pychess.metainfo.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
pychess.metainfo.xml -
This component contains no `developer` element with information about its author.
