surface
Let an agent explain surface as a locational concept, relay how surfaces and interfaces are treated in geometry, physics and geography from reference sources, describe idealised surfaces such as the celestial sphere, and distinguish the general concept from surface area as a measure, from mathematical surfaces and from specific anatomical surfaces.

What it is Filled
The extended two-dimensional outer boundary of a three-dimensional object, in the WordNet sense of the surface as a place, that is, the outermost layer or face of a body where it meets its surroundings, such as the surface of the Earth, a table or a liquid, including interfaces between two media and idealised surfaces such as the celestial sphere; the registry aliases also list the hard palate and roof of the mouth, which are anatomical surfaces rather than the general concept.
Why it exists Filled
Let an agent explain surface as a locational concept, relay how surfaces and interfaces are treated in geometry, physics and geography from reference sources, describe idealised surfaces such as the celestial sphere, and distinguish the general concept from surface area as a measure, from mathematical surfaces and from specific anatomical surfaces.
Distinguishing features Filled
- Two-dimensional boundary
- Locational sense
- Interfaces
- Idealised surfaces
What robots and AI may and may not do Filled
Must not
- Mix the locational sense with surface area or mathematical surfaces in explanations.
- Treat idealised surfaces as physical objects.
- Treat anatomical aliases as the same concept.
Only with a human decision
- Using surface descriptions in safety-critical inspection reports.
May
- Describe the surface of an object as the place where it meets its surroundings.
- Distinguish this locational sense from surface area and mathematical surfaces.
Moral aspects Filled
- Clear concepts matter for teaching and for technical writing.
- Mislabelled surfaces in inspections can hide defects.
Who is affected
- Students
- Technical readers
- Inspectors
Owners Filled
Steward
Nobody owns the concept.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.surface-location
- Open English WordNet: oewn-08677970-n
- WordNet: oewn-08529331-n the extended two-dimensional outer boundary of a three-dimensional object
Direct properties required Filled
- Earth surface area: about 510 million km^2
- interface examples: air-water, solid-liquid list
Recognition required Filled
- Outer boundary of a three-dimensional object
- Surface of the Earth, interfaces, celestial sphere; anatomical surfaces such as the palate as aliases
- Surface area is a measure; a mathematical surface is an abstract manifold; the palate is a specific anatomical structure
- Not a visible object as a concept; the outer face of any body.
Capabilities and actions required Filled
- explain the concept
- relay treatments in science
- describe idealised surfaces
- distinguish related senses
Hazards and failure modes required Filled
- Confusing the locational sense with surface area or mathematical surfaces
- Registry aliases mixing anatomy with the general concept
- Treating idealised surfaces as physical
Standards and interfaces required Filled
- No regulation of the concept; ISO geometric product specification for engineered surfaces
Context of use required Filled
- Not applicable; a general concept.
- surfaces of solid objects
- liquid surfaces and free surfaces
- interfaces between media
- planetary surfaces such as the surface of the Earth
- idealised surfaces such as the celestial sphere and the sphere
- anatomical surfaces listed as aliases such as the hard palate

Open questions
- Should interface and celestial sphere be separate primary entries?
- How should scientific sources be linked?
- The registry entry has merged anatomical aliases; should they be moved to hard palate?
