  # @note Extracting JSON components out of core is a work in progress.
  #
  # The {JSON} module includes functionality that is common between APIs using
  # JSON to send and receive data.
  #
  # The intent is to provide common code for provider APIs using JSON but not
  # require it for those using XML.
  #
  # @todo Add +require "fog/json" and/or +include Fog::JSON+ to providers using
  #   its services
