Data.UUID.V3

Description

NOTE: This module uses MD5 hashing. Unless you know you need to use this module, you should probably be using Data.UUID.V5, which offers the same sort of functionality as this module except implemented with SHA-1 hashing.

This module implements Version 3 UUIDs as specified in RFC 4122.

These UUIDs identify an object within a namespace, and are deterministic.

The namespace is identified by a UUID. Several sample namespaces are enclosed.
