Dome identity and geometry Establishes what is being called a dome and the geometry that bounds it.
Assembly identity
Identifies the physical referent and its relationship to adjacent coverings.
Dome referent
Record which covering or enclosure the name denotes and whether visible inner and outer forms belong to the same assembly.

Geometric envelope
Records footprint, profile and reference datums without assuming a standard dome shape.
Span, rise and profile
Describe the dome using referenced measurements that distinguish design geometry from surveyed geometry.

Covering construction
Separates structural fabric from finishes, linings and weather coverings.

Dome condition and intervention Connects located condition evidence with access, operation and proposed work.
Deformation and deterioration
Organises observations across the crown, dome surface, joints and base.
Located condition record
Record defects and changes with dates, locations, measurement methods and assessment status.
- What cracking, deformation, material loss or connection movement is recorded at the crown, across the surface and around the base? measurement

Access, operation and change
Records dome-specific prerequisites for inspection, movement and physical intervention.
Permitted dome actions
Link proposed actions to documented access provisions, operating requirements and technical constraints.
- Which routes, platforms or attachment points are documented for inspecting the dome, and what restrictions apply to surface access? action
- For a proposed penetration, added load, repair or support alteration, what assessment and authorisation are required before proceeding? action
- If the dome moves or depends on maintained pressure, what documented conditions permit operation and define an unavailable state? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
Reported evidence
Findings from the breadth pass, kept separate from the structural claims.
Kinds and varieties
Reported by the breadth pass; each item needs checking against its source before it becomes normative.
- Which of these kinds and varieties hold for the sense of dome this model covers, and on what evidence? provenance

What it is Filled
A dome is an architectural covering or enclosure resembling the hollow upper half of a sphere, typically hemispherical or near-hemispherical, whose construction may use a shell, ribs, a lattice or a tensioned membrane, used as a roof, building enclosure or protective cover.
In scope
- The dome's footprint, rise, profile, crown and relationship to the space it covers
- The shell, ribs, frame, panels or membrane that form the dome assembly
- Base restraint, bearing interfaces and dome-specific load-transfer arrangements
- Openings, weather protection and equipment integrated into the dome
- Observed condition, operating configurations and constraints on access or alteration
Out of scope
- The complete building, its programme and spaces beyond the dome's interface
- Foundations and supporting walls or columns beyond their connection to the dome
- Independent lighting, ventilation or astronomical equipment housed beneath the dome
- Site-wide planning, utilities and emergency management
- Geological domes, anatomical domes and dome-shaped products unless the registry explicitly includes them
Why it exists Filled
Enable an AI agent to recognise a dome, record its geometry and physical state, and identify uses or interventions that require evidence or specialist assessment.
Distinguishing features Filled
- Check whether the overall covering rises toward a crown across its footprint, rather than repeating an arch profile along an extended axis as a barrel vault does.
- Check whether a faceted form approximates a dome envelope or consists of planar roof faces meeting at a distinct apex; do not classify every pyramidal roof as a dome.
- Distinguish an externally visible dome from an interior domed ceiling, and establish whether they are separate assemblies.
- Check whether a small cupola is an independent assembly or a component atop a larger dome; record that relationship rather than assuming the terms are interchangeable.
- Distinguish geometric appearance from construction: a dome-shaped covering may use a shell, ribs, a lattice or a tensioned membrane.
What robots and AI may and may not do Filled
Must not
- Climb or load a dome without authority and safety measures.
- Alter a historic or religious dome without consent.
- Ignore signs of structural distress in an occupied building.
Only with a human decision
- Closing a building because of structural concerns.
- Restoration of a protected dome.
May
- Describe a dome's form, materials and structure, citing sources.
- Report cracks, leaks or loose material in domes it monitors for the owner.
Moral aspects Filled
- Domes crown many sacred and public buildings.
- Collapse would endanger many people beneath.
Who is affected

Open questions
- Does vr.tr.dome in INF / INF.MED denote an architectural dome, a media or projection enclosure, or another specialised referent?
- Which boundaries does the registry intend between dome, cupola, vault, domed ceiling, radome and geodesic enclosure?
- Does an existing Vercy world model already own this concept or any of its proposed assembly boundaries?
- Should movable and pressure-supported domes be covered through conditional layers here or through linked specialised models?
