Over at label-schema.org we've been reaching a consensus about some common keys for container labels which could be referred to by different tools.

I'm opening this issue to start a discussion about whether the OCI image spec could in some way reference label-schema - perhaps as an example of label key usage? If this is something folks are willing to see added to the spec, I'm more than happy to make a PR.

To be clear: we're not trying to suggest that a container has to have any of these labels! We're envisaging a future where tools extract metadata from a container, so having common keys could save users from having to add duplicate labels with the same information. A reference from the OCI image spec could really help establish the conventions.

Here's a list of public container images published on Docker Hub that are using label-schema labels today.
