Image name should allow uppercase letters

[wizpresso-steve-cy-fan]

Currently the spec mandates the name to be lower-cased, but there is no reason why. Rather than strictly following the rules, why don't we just relax it a little bit? Our company uses a capitalized name for our repos internally so this is quite annoying given that we cannot automatically link our container image by repo name anymore.

I don't believe there's any easy way to change this at this point without breaking a lot of code that validates image names. How would a change like this be rolled out without breaking existing runtimes and client tooling?

Would this also mean that registry.example.org/project:tag would be a different project from registry.example.org/Project:tag? If so, that feels like a high risk of typo squatting attacks. If not, then why not automatically convert all project names to lower case when lookup up the repo name?

That's a good point!

This was discussed in this week's OCI meeting and the consensus was that it's too late to make this change without breaking things.
