AppStream Report for Debian - Issues for grass-core in sid/main

Errors

metainfo-no-summary
Component does not contain a short summary. Ensure that the components MetaInfo file has a summary tag, or that its .desktop file has a Comment= field set.
More information can be found in the Desktop Entry specification and the MetaInfo specification.

no-metainfo
This software component is missing a MetaInfo file to provide metadata.
We currently took some data from its desktop-entry file and the long description of 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.
Additionally, a lot of software with desktop-entry files should either not be installable and searchable via the software catalog (like desktop-specific settings applications) or be tagged accordingly via MetaInfo files.
Please consider to either hide this desktop-entry file from AppStream by adding a X-AppStream-Ignore=true field to it, or to write a MetaInfo file for this component and send it upstream.
Generating components from non-MetaInfo files is deprecated, if you do not add a MetaInfo file, this software may vanish from the metadata catalog (and if it is a GUI application, no longer be visible in software centers) in a future distribution release.
You can consult the MetaInfo quickstart guides for more information on how to write a MetaInfo file, or file a bug with the upstream author of this software component.

gui-app-without-icon
The component is a GUI application (application which has a .desktop file for the XDG menu and Type=Application), but we could not find a matching icon for this application.

missing-launchable-desktop-file
The MetaInfo file references a .desktop file with ID 'org.osgeo.grass.desktop' in its launchable tag, but the file was not found in the same source tree. In order to be able to launch the software once it was installed, please place the MetaInfo file and its .desktop files in the same package.
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-developer-name-tag-deprecated
org.osgeo.grass.appdata.xml:54 -
The toplevel `developer_name` element is deprecated. Please use the `name` element in a `developer` block instead.
asv-desktop-app-launchable-omitted
org.osgeo.grass.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-content-rating-missing
org.osgeo.grass.appdata.xml -
This component has no `content_rating` tag to provide age rating information. You can generate the tag data online by answering a few questions at https://hughsie.github.io/oars/
asv-developer-info-missing
org.osgeo.grass.appdata.xml -
This component contains no `developer` element with information about its author.
