The Persistent Infrastructure Identity Registry
The registry responsible for issuing and maintaining persistent infrastructure identifiers (PIID) for physical assets across the built environment.
From Fragmented Documentation to Structured Registry Continuity.
What is the PIID Registry?
The Persistent Infrastructure Identity Registry is a neutral digital registry responsible for issuing and maintaining persistent identifiers for physical infrastructure assets.
The registry establishes a continuous digital identity for infrastructure assets so lifecycle records such as design documents, inspections, maintenance events, repairs, and upgrades remain attached to the same asset across time.
This persistent identity allows infrastructure records to remain connected even as ownership, contractors, software systems, or service providers change.
The registry functions as the identity layer of the built environment, enabling infrastructure information to be structured around the physical asset itself rather than fragmented across independent systems.
Core Registry Functions
Identifier Issuance
The registry issues Persistent Infrastructure Identity Identifiers (PIIDs) for physical assets.
Each identifier serves as the permanent digital identity of the asset.
Identifiers are designed to remain persistent across ownership changes, system migrations, and lifecycle events.
Lifecycle Record Continuity
Infrastructure lifecycle records attach to the identifier over time.
These records may include:
• design documentation
• construction records
• inspection reports
• maintenance events
• repair and upgrade documentation
• risk mitigation improvements
• insurance inspection data
The result is a continuous operational history for the asset.
Lifecycle Record Continuity
Infrastructure lifecycle records attach to the identifier over time.
These records may include:
• design documentation
• construction records
• inspection reports
• maintenance events
• repair and upgrade documentation
• risk mitigation improvements
• insurance inspection data
The result is a continuous operational history for the asset.
Identity Resolution
The registry allows authorized stakeholders to reference the same infrastructure asset through a shared identifier.
This enables systems across the built environment to interact with the same asset identity without requiring full system integration.
Registry Integrity & Identity Controls
Because infrastructure identity must function as trusted digital infrastructure, the registry incorporates several safeguards designed to maintain identifier integrity.
These include:
• duplicate identity detection mechanisms
• structured asset referencing
• append-only lifecycle records
• role-based access controls
• verifiable audit logging
These controls ensure that infrastructure identity remains consistent and verifiable across the lifecycle of the asset.
Multi-Stakeholder Participation
Registry Participation
Multiple stakeholders may interact with the registry under governed permissions.
These may include:
• property owners
• engineering and inspection professionals
• contractors and service providers
• asset managers
• insurance carriers
• infrastructure operators
Each participant interacts with the asset through the same persistent identifier, enabling lifecycle information to accumulate around the infrastructure asset itself.
Registry Governance
Governance
The registry operates under structured governance principles designed to maintain neutrality and long-term infrastructure continuity.
Identifiers are tied to the physical asset rather than any individual organization.
Lifecycle records follow an append-only structure to preserve historical continuity.
Registry oversight and participation frameworks are designed to support long-term infrastructure identity stability across the built environment.
