Abstract

AppStream is a collaborative effort for enhancing the way we interact with the software repositories provided by the distribution by standardizing sets of additional metadata.
AppStream provides the foundation to build software-center applications. It additionally provides specifications for things like an unified software metadata database, screenshot services and various other things needed to create user-friendly application-centers for software distributions.
You can find a C/GLib based reference implementation of the specification here and report bugs about the implementation as well as the specification itself at the issue tracker.
