What it is Filled
A spatial location defined by a real or imaginary one-dimensional extent, such as a railway track, a main or feeder line in a network, a coordinate axis, a data track on a disc, a boundary line or a route marked on a map; in this sense a line is a place or path rather than a geometric abstraction, a written row of text or a queue.
Why it exists Filled
Let an agent interpret line as a spatial location or path, distinguish it from other senses, and support questions about tracks, routes, axes and boundaries.
Distinguishing features Filled
- Spatial
- One-dimensional
- Real or imaginary
- Named by function
What robots and AI may and may not do Filled
Must not
- Treat a disputed or approximate boundary line as settled and exact.
- Enter or work on a railway or power line without the operator's authority and protection.
- Give route references that could send people onto the wrong line or track.
- Move or alter markers that show where a boundary or service line runs.
Only with a human decision
- Deciding where a boundary line lies in a dispute.
- Authorizing work near live lines or active tracks.
May
- Locate and describe a line, such as a railway, network feeder or boundary, from authoritative maps and records.
- State which sense of line is meant when the word is ambiguous.
Moral aspects Filled
- Lines on the ground divide property and territory; misplacing them takes from someone.
- Railways and power lines are deadly places for people who do not know they are live.
Who is affected
- Landowners on either side
- Workers near lines
- Travellers and users of a network
Owners Filled
Steward
Depends on the line: the infrastructure operator for tracks and networks, the land or boundary authority for boundaries.
Master systems
- Cadastre and boundary records
- Infrastructure operators' asset registers

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.line-3
- Open English WordNet: oewn-08610818-n
Direct properties required Filled
- Path length: metres - Measure distance along a specified finite path or between defined endpoints using survey data or spatial coordinates.
- Local curvature: inverse metres - Determine the change in path direction per unit distance from surveyed or modelled coordinates where the path is smooth.
Recognition required Filled
- One-dimensional spatial extent
- Real or imaginary
- A geometric line has no physical location
- A path, track or marked extent on the ground, a map or a device.
Capabilities and actions required Filled
- interpret which spatial line is meant
- explain tracks, routes and axes
- distinguish from other senses
- support mapping and navigation
Hazards and failure modes required Filled
- Confusing senses of line
- Ambiguous route references
- Misreading boundary lines
Standards and interfaces required Filled
- Mapping and survey conventions
- Transport network naming conventions
Context of use required Filled
- Naming one-dimensional places and paths.
- railway and transit lines
- main and feeder lines in networks

Open questions
- Should each spatial sense be a separate entry?
- How should transport data be linked?
- How should survey lines be linked?
