scope:
This Recommendation | International Standard specifies the format and generation rules that enable users to produce 128-bit identifiers that are either guaranteed to be globally unique, or are globally unique with a high probability.
The universally unique identifiers (UUIDs) generated in conformance with this Recommendation | International Standard are suitable either for transient use, with generation of a new UUID every 100 nanoseconds, or as persistent identifiers.
This Recommendation | International Standard is derived from earlier non-standard specifications of UUIDs and their generation, and is technically identical to those earlier specifications.
This Recommendation | International Standard also specifies and allows the use of UUIDs as primary values (which define Unicode labels) for arcs beneath the Joint UUID arc. This enables users to generate and use such arcs without any registration procedures.
This Recommendation | International Standard also specifies and allows the use of UUIDs to form a uniform resource name (URN).
