Hi all. I'm the developer for PackageKit and gnome-software, the

At the moment, we use the information in the .desktop file to populate
the AppStream data, but this is missing a few core things, for
instance a long description, the upstream website for the application
and any screenshots to show. All of the three being quite critical to
assess an application before installing. To fix this I've created a
tiny AppData specification [1] which is a subset of the AppStream
specification. It's designed as a way to describe the application (not
the package) so that data can be used in the AppStream data.

As a first step to create such a database, can you reuse metadata avalable on Ohloh?

It seems they already have much of what you need.

Bye,

Andrea.
