taginfo: railway:signal:*

This page describes a key prefix rather than a simple key.

Description

The value of this tag is a key prefix (or namespace) for country-specific values of all the railway:signal:* tags that describe the signal.

With this tagging scheme, the prefix is specified only once using this tag and implicitly prepended to any country-specific values, making the describing tags easier to read.

A namespace, like a prefix, is composed of a two-letter country code (ISO_3166-1) optionally followed by some country-specific values (e.g. DE-ESO, AT-V2, FR).

This tagging scheme is optional and does not replace the existing tagging scheme with prefixed values.

Examples

Without using the prefix tag

In Germany:

• railway=signal
• ref=51VA
• railway:signal:direction=forward
• railway:signal:position=right
• railway:signal:distant=DE-ESO:ks
• railway:signal:distant:form=light
• railway:signal:distant:height=normal
• railway:signal:distant:states=DE-ESO:ks1;DE-ESO:ks2

In Austria:

• railway=signal
• ref=H503
• railway:signal:direction=backward
• railway:signal:position=right
• railway:signal:main=AT-V2:hauptsignal
• railway:signal:main:form=light
• railway:signal:main:states=AT-V2:halt;AT-V2:frei;AT-V2:frei_mit_60
• railway:signal:main:function=exit
