In an era where software systems are increasingly complex and interconnected, effectively managing the relationships between packages, maintainers, dependencies, and vulnerabilities is both a challenge and a necessity. This paper explores the integration of knowledge graphs into the Debian ecosystem as a powerful means to bring structure, semantics, and coherence to diverse sources of package-related data. By unifying information such as package metadata, security advisories, and reproducibility reports into a single graph-based representation, we enable richer visibility into the ecosystem’s structure and behavior. Beyond constructing the DebKG graph, we demonstrate how it supports practical, high-impact applications — such as tracing vulnerability propagation and identifying gaps between community needs and development activity — thereby offering a foundation for smarter, data-informed decision-making within Debian.
