extent
Let an agent explain extent as a spatial magnitude, relay how extents are measured and described in surveying, geography and law from reference sources, describe the figurative aliases, and distinguish extent from area, distance and volume as specific quantities and from the other senses of the aliases.

What it is Filled
The distance, area or volume over which something extends, in the WordNet sense that groups measures of spatial reach such as frontage along a street, scope, range, reach, compass and orbit in their spatial and figurative uses; extent is a general magnitude attribute used in geography, law, surveying and everyday description.
Why it exists Filled
Let an agent explain extent as a spatial magnitude, relay how extents are measured and described in surveying, geography and law from reference sources, describe the figurative aliases, and distinguish extent from area, distance and volume as specific quantities and from the other senses of the aliases.
Distinguishing features Filled
- General spatial magnitude
- Linear, areal or volumetric
- Figurative extensions
- Legal and surveying use
What robots and AI may and may not do Filled
Must not
- State an extent without units or a source when exactness matters.
- Confuse the spatial and figurative senses of extent in legal or survey contexts.
- Misstate the extent of a property or boundary to favour one party.
- Present an estimated extent as a surveyed one.
Only with a human decision
- Using an extent figure to settle a boundary or property dispute.
May
- Describe the extent of a place or object using measured values and their sources.
- Distinguish extent as a general idea from specific measures such as length or area.
Moral aspects Filled
- Boundaries and frontage decide property rights and taxes.
- The extent of damage or harm is often disputed and should be stated honestly.
Who is affected
- Property owners
- Neighbours
- Surveyors and officials
Owners Filled
Steward
Nobody owns the concept; surveyors and land registries record the extent of real property.
Master systems
- Land registry or cadastre for property extents

Recognition optional Filled
- Distance, area or volume covered
- Frontage, scope, range, reach, compass, orbit
- Area, distance and volume are specific quantities; orbit and range have other technical senses
- Not a visible object; a spatial magnitude.
Capabilities and actions required Filled
- explain the concept
- relay measurement and description
- describe figurative uses
- distinguish related quantities
Hazards and failure modes required Filled
- Confusing extent with specific quantities
- Ambiguity between spatial and figurative senses
- WordNet aliases with distinct technical meanings
Standards and interfaces required Filled
- Surveying and cadastral standards
- Geospatial metadata standards for extent
Context of use required Filled
- Describing how far something extends.
- linear extent such as frontage and length
- areal extent such as the extent of a territory or map
- volumetric extent
- figurative extent such as scope and reach
- extent in data and mapping such as bounding boxes
Sources Filled
- Open English WordNet 2024, synset oewn-05130681-n - sense and gloss of the concept

Open questions
- Should frontage and scope be separate entries?
- How should reference sources be linked?
