AppStream is a collaborative effort for making machine-readable software metadata easily available to programs that need it. It is part of the Freedesktop ecosystem and provides a convenient way to retrieve information about available software, making it one of the building blocks for modern software centers. AppStream consists of a specification to describe individual software component metadata in XML (so-called MetaInfo files), as well as a derived specification for a metadata-collection format to provide a list of these metadata entries in XML or YAML for easy consumption by software centers and other tools which need to know about available software in a repository. In addition to the metadata specification, AppStream specifies a set of related features to help providing better metadata for software repositories (primarily in Linux distributions). This reference implementation of AppStream provides a shared library to work with these metadata files, features to index and query their data quickly, as well as other useful related functionality to make building programs which work with software metadata very easy.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
