This PEP describes a way to record the provenance of installed Python distributions. The record is created by an installer and is available to users in the form of a JSON file provenance_url.json in the .dist-info directory. The mentioned JSON file captures additional metadata to allow recording a URL to a :term:distribution package together with the installed distribution hash. This proposal is built on top of PEP 610 following :ref:its corresponding canonical PyPA spec <packaging:direct-url> and complements direct_url.json with provenance_url.json for when packages are identified by a name, and optionally a version.
