Here a re a list of issues that came up in today's call (11/11/2020):

• Accept headers
• Show examples of types of manifests (OCI index, etc.)
  • need to see example of what this might look like, not as a requirement
• unclear manifest vs. blob, what goes where
• existence check of a blob (under Push section)
• Show "Pushing a blob in chunks" first since they are more broadly supported
• "A single POST request" should possibly be removed
• Content-Type: application/vnd.oci.image.manifest.v1+json does not include what is required for indexes
• "The uploaded manifest MUST reference any blobs that make up the artifact. However, the list of blobs MAY be empty."
  • For an image, this must reference one blob
  • Respect for "non-distributable" layers
• " The is a pullable manifest URL."
  • what is pullable manifest URL?
  • do clients actually provide this header?
