Improve AppStream metainfo
AppStream metainfo files are really helpful for other services to automatically showcase KDE apps. You should make sure (e.g. via automatic pipeline checkers) that this file exists, data is up to date, important fields are set and consistent among apps.
One example is the link format of donation URLs which is inconsistent or completely missing among apps.
More context
I started making use of AppStream metainfo for Linux Phone Apps (you can find my current checkers using Python here).
The current version of the database is apps.csv (see column appstream_xml_url
for links to AppStream files, note that many applications are hosted on https://invent.kde.org/
I don't know based on which data https://apps.kde.org/ is generated. My idea is based on GNOME's https://apps.gnome.org/ (repo) which is using AppStream metainfo files via Flatpak. In order to keep the data consistent, they started an initiative here.
