https://github.com/opencontainers/distribution-spec/blob/main/spec.md#appendix

• Audit errors raised during manifes/manifest list push #625
• Add support for the application/vnd.oci.artifact.manifest.v1+json media type #1164
• Add support for the Referrers API #1169

[ipanova]

Artifact media type and referrers API were recently introduced we might want to add support to that.

@lubosmj this ticket might need to be split into 2. I think 1) add support for artifact mediatype 2) add support for refferers API. I am suggesting to start with the former and create a separate ticket once you get more info for the 2.

[ipanova]

and in case you find other gaps during the audit please file more tickets respectively ;)

[lubosmj]

Sure, will do that. It might be worth creating an epic for this.

Per my understanding the audit was completed and needed issues were filed separately. This issue was transformed into an EPIC to track the remaining work.
