Welcome!

Welcome to the AppStream Generator HTML pages!

These pages exist to provide a user-friendly view on the issues discovered by the AppStream metadata generator while extracting metadata from packages in the neon/stable archive. They can also be used to take a look at the raw metadata, to spot possible problems with the data itself or the generation process.

What is AppStream?

AppStream is a cross-distro XML format to provide metadata for software components and to assign unique identifiers to software.
In neon/stable, we parse all XML provided by upstream projects as well as other metadata (.desktop-files, ...), and compile a single metadata file from it, which is then shipped to users.

The generated metadata can for example be used by software centers like GNOME Software or KDE Discover to display a user-friendly application-centric view on the package archive.
It can also be used by other software to find missing plugins, codecs, fonts, etc. or simply by users to install software on any Linux distribution without knowing the exact package name.
