The Role of Package Managers as Partners in License and Attribution Compliance
summary
Package managers routinely hide transitive changes so ten or twelve declared dependencies balloon to hundreds of transitive deps and a single version bump can cascade 200+ changes through the tree. Metadata formats differ across FreeBSD ports, Debian, pip/pyproject.toml and npm and fields for license or scope are often optional or inconsistent so tools like ClearlyDefined, FOSSA, SPDX/CycloneDX SBOMs only partially work. Practical fixes proposed are a minimal, non-language metadata set, explicit scoping and treating bundleDependencies means redistribution so attribution is accurate and SPDX expressions adopted across registries.
