Data::UUID provides a framework for generating v3 UUIDs (Universally
Unique Identifiers, also known as GUIDs (Globally Unique Identifiers).
A UUID is 128 bits long, and is guaranteed to be different from all
other UUIDs/GUIDs generated until 3400 CE.
.
UUIDs were originally used in the Network Computing System (NCS) and
later in the Open Software Foundation's (OSF) Distributed Computing
Environment. Currently many different technologies rely on UUIDs to
provide unique identity for various software components. Microsoft
COM/DCOM for instance, uses GUIDs very extensively to uniquely identify
classes, applications and components across network-connected systems.
.
The algorithm for UUID generation, used by this extension, is described
in the Internet Draft "UUIDs and GUIDs" by Paul J. Leach and Rich Salz.
(See RFC 4122.) It provides reasonably efficient and reliable
framework for generating UUIDs and supports fairly high allocation
rates -- 10 million per second per machine -- and therefore is suitable
for identifying both extremely short-lived and very persistent objects
on a given system as well as across the network.
