What it is Derived, awaiting review
This meta-model describes roads, rail, pipes, grids and cables as physical networks: the topology of segments and nodes, their rated capacity and utilization, and their asset condition and maintenance.
Note: First sentence of the legacy card introduction.
Why it exists Filled
Roads, rail, pipes, grids as physical networks
Distinguishing features Derived, awaiting review
- It is its own model because the physical asset base persists across operators and service arrangements, and its topology is the shared substrate that service points (U5), settlements (U4) and incidents (X3) all reference.
What robots and AI may and may not do Missing, in the backlog

Owners Filled
Steward
The owner archetype is the operator organization: the operator of each network stewards its asset records, and several operators can steward different networks over the same territory.

- world.buildingStructure - carrying structures such as bridges and tunnels are modelled there
- world.utilityServicePoint - where end users tap the network; supply semantics live in U5
- world.settlementUrbanForm - segments traverse settlements and districts modelled there
- world.landParcelCadastre - rights of way and easements over parcels are resolved in the cadastre
- world.incidentEmergency - incidents affecting network assets are recorded there and mirrored as closure events here

Capabilities and actions required Derived, awaiting review
- segmentCommissioned: a new segment entered service
- segmentDecommissioned: a segment was permanently withdrawn from service
- capacityRerated: a segment or node received a new capacity rating
- conditionSurveyed: a condition survey was completed and graded
- maintenanceCompleted: planned or corrective upkeep was finished on an asset
- closureOccurred: a segment was temporarily closed or out of service
Legacy events listed as state transitions.
Hazards and failure modes optional Missing, in the backlog

Standards and interfaces required Derived, awaiting review
- openNetworkMapLicense: public release of simplified topology for mapping and routing
- interOperatorExchange: exchange of connectivity and capacity data at interconnection points between operators
- conditionDataAccess: operator-granted access to condition surveys for engineers, insurers or works planners
- routingGraphProjection: topology and capacity as a graph for pathfinding; omits condition and maintenance detail
- assetRegisterProjection: assets with age, condition grade and maintenance state; omits utilization
- publicMapProjection: simplified geometry and classification for general maps; omits operationally sensitive attributes
Context of use required Filled
- Access to condition and capacity detail is granted by the operator through S2, with disclosures auditable via S4.
