We expect a single log to be able to handle submissions for different packaging systems so we should design a common metadata format.
As a strawman we can use a different key-pair for log submission than release keys.
Action items:
Al and Adam to think about how to modify the CT codebase to accept arbitrary data authenticated with a public/private key-pair that we can use to experiment with.
Ed and dkg to start a proposal for a common metadata format.
