appstream

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.

sudo apt install appstream
