Universally Unique Identifier

A Universally Unique Identifier is an identifier standard used in software construction, standardized by the Open Software Foundation (OSF) as part of the Distributed Computing Environment[?] (DCE). The most widespread use of this standard is in Microsofts Globally Unique Identifiers (GUIDs) which implement this standard.

A UUID is essentially a 16-byte number and in its canonical form a UUID may look like this:

550E8400-E29B-11D4-A716-446655440000
