libappstream5 binary package in openKylin Nile V2.0 loong64

 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 a GObject-based library to access AppStream
 services, like the software component metadata pool.
 It also contains functions for reading, writing and transforming AppStream
 metadata.
