Dev:CommonDataTypes

This page is used to collect all data types used in the schemas. The target is to harmonize and re-use data types throughout the different schemas.

Simple Types

"Simple Types" are scalars based on integers or floating point numbers. The describe values like time, length or velocities. Vectors, lists (enumerations) or structures are not covered in this section!

Scalar's Name	Scalar's Unit	Encoding	Used in ...				Comment
			IS	IL	RS	TT
Position, distance, radius	km	float (0.3)	x				May occur as absolute or relative Position along the track, as abs. or rel. offset, as distance between two points, as radius or as superelevation
Latitude, Longitude, Altitude	?	float	x				Geographical position. The used coordinate system is still under discussion.
Owner Name
string	X
UIC-Number
integer					UIC-No. which belongs to a <<Owner>>.
Voltage	V	integer	x
Frequency	Hertz (1/s)	float	x
Gauge	m (?)	float (0.3)	x
Weight	kg	float	x
Axle Load ("meterload")	kg/m	float	x				Is this correct?
Speed	km/h (?)	float	x				Or did we agree on [m/s] in the last meeting?
Angle
float					Should we really use radian instead of grad (2 Pi = 360 Grad)?
Country ID (for Balises)
integer	x
Group ID (for Balises)
integer	x
Point (Coordinates on a screen)	pixel	float	x				Used in the visualization part. Shouldn't the unit be integer?
Size (Screen size of an element)	pixel	float	x				Used in the visualization part. Shouldn't the unit be integer?
