I can't think of any API in OpenStack that uses a URI for referencing
anything.  We may have *links* in the payloads, but those are provided
for convenience; anytime nova refers to a flavor, it returns the flavor
UUID.

I would, by the way, suggest using UUIDs rather than plain IDs, for
consistency with the rest of the APIs…
