UUID is an abbreviation for Universally Unique Identifier. It is a standard for software construction and is part of the Open Software Foundation organization in the field of distributed computing environments. UUID is a 128-bit value that can be calculated by a certain algorithm. For efficiency, the commonly used UUID can be shortened to 16 bits. UUIDs are used to identify attribute types and are regarded as unique identifiers in all spaces and times. Generally, it is guaranteed that this value is truly unique. Any UUID generated anywhere will not have the same value. One advantage of using UUIDs is that new identifiers can be created for new services. The standard UUID format is xxxxxxxx-xxxx-xxxx-xxxxxx-xxxxxxxxxx (8-4-4 -4-12).
