appstream binary package in Ubuntu Mantic 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.
 The AppStream project provides facilities to easily access and transform
 this metadata, as well as a few additional services to allow building
 feature-rich software centers and similar applications.
 .
 This package provides tools to generate, maintain and query the AppStream
 data pool of installed and available software, and enables integration
 with the APT package manager.
 .
 The 'appstreamcli' tool can be used for accessing the software component
 pool as well as for working with AppStream metadata directly, including
 validating it for compliance with the specification.
