Should this be converted to https://github.com/package-url/purl-spec ?

Maybe. I'm not entirely sure, in-toto doesn't require it, so it's up to us. I do think we want to make sure that the platform is present in the name though (to ensure uniqueness), since then we'll have a 1-to-1 relationship between digests and names.
So maybe PURL would be the right choice here, with the version field containing the image tag, and the image repository location and architecture/os data in the qualifiers? Not sure whether we should use the sha256: in the name though, since that would be duplicated.

Have cherry-picked your PURL util package (with a fixup to use reference for the distribution reference package, like we have in the other parts of the codebase).

btw, the reason I used the specific name was that there is also
https://github.com/containerd/containerd/tree/main/reference and
https://github.com/moby/moby/tree/master/reference

Yeah that makes sense, I think we should make that change everywhere then at some point, instead of just here.

Happy to do that in a follow-up, if this is a blocker 👍

Use convention of importing docker/distribution/reference as reference. Signed-off-by: Justin Chadwell <me@jedevc.com>
