What it is Derived, awaiting review
This meta-model describes cities, towns and villages and their internal spatial anatomy: districts, blocks, built-up extents, density and morphology.
Note: First sentence of the legacy card introduction.
Why it exists Filled
Cities, districts and urban morphology
Distinguishing features Derived, awaiting review
- It is its own model because urban form is an aggregate view over buildings (U1) and networks (U3) that changes slowly, is analyzed at its own scales, and is stewarded by planning and statistical actors rather than by individual asset owners.
What robots and AI may and may not do Missing, in the backlog

Owners Filled
Steward
The owner archetype is the settlement steward, a municipal planning office archetype for form records and a statistics office archetype for derived aggregates.

Direct properties not applicable Not applicable
Not applicable
Institutional or informational subject: no invented physical properties.
Recognition optional Missing, in the backlog
Not described yet. This gap is in the card backlog.
Capabilities and actions required Derived, awaiting review
- extentObserved: a new built-up extent was measured for a settlement
- districtRedrawn: district boundaries were changed
- blockReplatted: block geometry was restructured, typically after redevelopment
- densityMeasured: a density value was computed for a spatial unit at a reference date
- classificationChanged: a settlement or district moved to a different scheme term
Legacy events listed as state transitions.
Hazards and failure modes optional Missing, in the backlog
Not described yet. This gap is in the card backlog.
Standards and interfaces required Derived, awaiting review
- openUrbanFormLicense: public release of extents, blocks and density aggregates
- planningBaselineAccess: steward-granted access to full morphology data for plan-making
- statisticalExchange: delivery of aggregates to a statistics office under agreed definitions
- atlasProjection: settlements, districts and extents for reference mapping; omits per-building detail
- planningBaselineProjection: form and density indicators for plan-making; omits any owner or occupant information
- growthTimelapseProjection: successive extents in time order; omits internal subdivisions
Context of use required Filled
- The steward grants access per S1/S2, and published aggregates carry their scheme and reference date so consumers can detect drift.
