Micro Micro level (for railways) is associated with tracks. It is the level where vehicle paths are unambiguous. At micro level, the smallest details aggregate into a single item. E.g. individual point components and point blades and tips coalesce into a single turnout.
Nano The nano level (for railway) is the level where track geometry and, in particular, curvilinear abscissas would be in agreement with on-board odometry. It is used for detailing crossing geometry, for instance. The nano level could be described as a properly attributed surveyor's map, including topological properties of the rail network in the finest possible granularity. Use cases for the Nano level would include interlocking and asset management.

They shall not be considered properties of the connection itself.

Defines geographic or geodetic reference system used to position instances of NetElement or NetEntity. About epsgCode, see e.g. epsg.io.
Design note about navigability=none. None is an extraneous value - a graph would have no edge at all in such case. It conveys the meaning that NetElements are "adjacent", which makes no sense in graph theory but would have a meaning in mathematical topology (you cannot insert any NetElement between). This is a slight but practical concession to conceptual purity. To keep the real connectivity we need all the edges and the "none" value, else the connectivity graph (same for the line graph) is not properly formed with regard to the original graph.

Abstract property class, needed to implement the composite pattern.
A referencing system for locations relative to a one-dimensional object (reference line) as measurement along (and optionally offset from) that object. For reference, see EN 19148:2021. A linear positioning system combines a line of reference (here: a collection of PositioningNetElements) with a single number (linear abscissa, i.e. an instance of class LinearCoordinate) allowing positioning within a railway network, at the chosen level (MACRO, MICRO...). Often called chainage (when yielding the actual "distance along"), or mileage system (when reflecting a conventional kilometric post or mile post system). The start- and end-measures (optional) provide the valid range of linear coordinates within the chosen linear positioning system. The difference between two coordinates is not necessarily the "true distance along" because of possible deviations (jumps or systematic errors), that are taken care of by anchor points and linear referencing methods. The units of linear abscissa are the same as the start and end-measure.
A spatial reference system in which a position can be expressed in terms of coordinates.
Provides basic information about location in the network topology information. "Location" is an abstraction for "some place in space that is used by some NetEntity". The location per se offers no information about position on earth.
