2.2.3 Universally Unique Identifiers (UUIDs)
|For Standard||CTA v2.1|
To manipulate and exchange data objects independently, each instance of an Energistics data object requires a universally unique identifier (UUID).
Energistics uses UUID standard RFC 4122 from the Internet Engineering Task Force (IETF) (https://tools.ietf.org/html/rfc4122 ).
According to the abstract of the RFC: "This specification defines a Uniform Resource Name namespace for UUIDs (Universally Unique IDentifier), also known as GUIDs (Globally Unique IDentifier). A UUID is 128 bits long, and can guarantee uniqueness across space and time."
For UUIDs, Energistics standards are case-insensitive.
For more information about use of UUIDs by Energistics, see the Energistics Identifier Spec.
