Ubuntu already publishes cloud image metadata in a machine parseable and
cryptographically safe, mirrorable way. The format is extremely generic
and can be used to publish metadata about any product that publishes
things of incrementing releases. Our implementation is a Python library.
It looks remarkably similar to your proposal:
https://cloud-images.ubuntu.com/releases/streams/v1/com.ubuntu.cloud:released:download.json
The format also provides for information about our images published
elsewhere. For example,
https://cloud-images.ubuntu.com/releases/streams/v1/com.ubuntu.cloud:released:aws.json
allows you to cross-reference this metadata against Amazon AMI IDs (and
data is currently also published for Azure, Brightbox, CloudSigma, GCE,
HP Cloud, Joyent and Rackspace).

Please consider what we have before creating Yet Another Standard :-)
