libappstream-compose0 binary package in openKylin Yangtze V1.0 arm64

 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 of high-level functions
 to compose AppStream metadata and auxiliary data (like font renderings,
 icons, etc.).
