DOI is an application of the Handle System (http://www.handle.net), which is
a global name service. Every DOI is a Handle in the Handle System, and DOIs
are registered and resolved using Handle System Resolution and
Administration protocols.

The DOI namespace, a sub-namespace of Handle System name space, _is_
heirarchical.  In terms of DOI, this hierarchy is reflected in the DOI
"Prefix", and the way it is assigned or used. The DOI "Prefix" is equivalent
to the Naming Authority in the Handle System, which serves as an
administrative unit for a sub-namespace, and the sub-namespace could in term
define its own sub-namespace, and so on. (It is worth noting that although
the namespace is heirarchical, the resolution protocol is not, so as to
achieve minimum number of round trips, and to ensure global uniqueness.)
