          A *resource* is a JSON-serializable object organized as a tree.
          Each node is a scalar, indexed array, or dictionary. Structs and
          classes are represented by dictionaries indexed by member name.

          Each node is reachable by a unique path of names from the root. A
          node *key* is the path names separated by '.'. [_number_] represents
          an array index. For example:

            foo
            foo.bar
            abc.def[3].ghi

          The resource keys and data values for any _gcloud_ _list_
          command can be printed by running _gcloud_ ... _list_
          *--format=flattened*. See the command specific documentation for
          details on specific resource keys.
