line
a spatial location defined by a real or imaginary unidimensional extent
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
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.
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.
What it is for: Naming one-dimensional places and paths.
It can be interpret which spatial line is meant; explain tracks, routes and axes; distinguish from other senses; support mapping and navigation.
Distinguishing features
Spatial
One-dimensional
Real or imaginary
Named by function
What it looks like
A path, track or marked extent on the ground, a map or a device.
How it is recognised
One-dimensional spatial extent
Real or imaginary
A geometric line has no physical location
