UIDNU: Unique Identification Number

Overview

UIDNU (Unique Identification Number) is a persistent identifier system designed for uniquely referencing both digital and physical objects through standardized numerical codes. It provides a deterministic or generated numeric value assigned to each entity, ensuring unambiguous identification within a defined system domain.

Core Concept

At its foundation, UIDNU establishes a canonical reference system where every object—whether digital or physical—receives a unique numerical identifier. This identifier remains persistent throughout the object's lifecycle, enabling consistent referencing across different contexts and applications.

Integration Ecosystem

The UIDNU system is built with interoperability as a core principle. It can seamlessly interconnect with existing identification systems through crosswalk mappings, which serve as translation layers between different identifier schemes. This approach allows objects to maintain multiple identifiers from various systems while preserving a single, canonical UIDNU reference as the authoritative identifier.

Key Characteristics

Persistence: Once assigned, a UIDNU remains permanently associated with its entity, providing long-term referencing stability.

Uniqueness: Each UIDNU is guaranteed to be unique within the system domain, eliminating ambiguity in object identification.

Standardization: The numerical coding follows standardized formats, ensuring consistency and machine-readability across implementations.

Interoperability: Through crosswalk mappings, UIDNU bridges existing identification systems, enabling unified reference management without disrupting established workflows.

Applications

The UIDNU system can be applied across diverse domains including digital asset management, physical inventory tracking, research data repositories, library systems, and any context requiring reliable, persistent identification of distinct entities.
