UUIDtä
UUIDtä is a term used in theoretical discussions of identifiers to describe a composite form that combines a standard UUID with a short, application-defined tag. The idea is to attach lightweight semantic information to a globally unique identifier without changing the underlying uniqueness guarantees of the UUID portion. UUIDtä is not part of any formal standard; it is a conceptual construct used for explanation and design discussions.
Structure and encoding methods
A UUIDtä consists of two parts: a 128-bit UUID (as defined by RFC 4122) and a tag
The UUID part uses standard generation methods (random, DCE security, or namespace-based) to ensure global uniqueness.
UUIDtä can facilitate quick filtering in logs, routing decisions in microservices, or multi-tenant data organization. However,
