D-Bus is a message bus system, a simple way for applications to talk to
one another. D-Bus supplies both a system daemon and a
per-user-login-session daemon. Also, the message bus is built on top of
a general one-to-one message passing framework, which can be used by
any two apps to communicate directly (without going through the message
bus daemon).
Paths come from the repository package-file index for the observed builds. They describe archive/package associations, not every file that will exist on a running system after maintainer scripts, alternatives, generated state, diversions, or installation choices.
Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.
