gir1.2-appstream-1.0 0.16.1-1ubuntu1 (amd64 binary) in ubuntu mantic

 AppStream is a metadata specification which permits software components to
 provide information about themselves to automated systems and end-users
 before the software is actually installed.
 This permits informative displays of new applications to users in software
 centers, as well as allowing a system to make decisions on which new software
 a user might want to install (e.g. missing firmware or media handlers).
 .
 This package contains introspection data for the AppStream library.
