      [Applied]

      As we defined a list of compatible changes to the data model of a service, it would be useful to notify clients that the metadata has changed, so they can re-read $metadata.

      As the new JSON format in two of its flavors already includes the metadata link, we could just add a metadata etag that clients can compare to the etag of the cached version of $metadata.

      While we are at it, we can add a metadata link to Atom responses.
