SyntheticIdComponent

Generalization is DataStructureComponent.

Superclass hierarchy

Definition

Persistent and unique identifier (PIDs) to provide standarized, long-lasting identification.

Examples

UUIDs, GUIDs, DOIs, URNs or any other unique id generation framework.

Explanatory notes

This PIDs either complement or replace identifier and dimension components. They complement them when there is a need for having a globally unique identifier as part of an instance key. They replace them when identier components are not available (e.g. after de-identification for confidentiality).
