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
  • coordinate axes
  • data tracks on media
  • boundary and survey lines

Sources Filled

  2. Wiktionary: line - word senses and usage

Open questions

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