# Relationships

Artifacts may have the following relations with each others:

- built-using: indicates that the build of the artifact used the target artifact (ex: “binary-packages” artifacts are built using “source-package” artifacts)

- extends: indicates that the artifact is extending the target artifact in some way (ex: a “source-upload” artifact extends a “source-package” artifact with target distribution information)

- relates-to: indicates that the artifact relates to another one in some way (ex: a “binary-upload” artifact relates-to a “binary-package”, or a “package-build-log” artifact relates to a “binary-package”).
