# AppStream

## Infrastructure for distro-agnostic software-centers and universal software component metadata

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 full specification at github.com/ximion/appstream (https://github.com/ximion/appstream) and report bugs about the implementation as well as the specification itself at the issue tracker (https://github.com/ximion/appstream/issues). The project also provides a web form for the simple creation of metainfo XML files for upstream maintainers at freedesktop.org/software/appstream/metainfocreator (https://www.freedesktop.org/software/appstream/metainfocreator/#/).
