Hi,
Can somebody please write a brief documentation to
http://wiki.openstreetmap.org/wiki/Key:symbol
I'm not sure I understand the tag's use. We are currently discussing the
use on the Hungarian mailing list, would be great to have some pointers,
"standard".
----IDEAS ONLY - please copy to wiki, adjust, or rewrite----
The symbol tag is used for describing hiking trails by a human readable
name. It is usually accompanied with {{Key|osmc:symbol}}, which contains
a machine readable description of the hiking trail. Example:
symbol = red bar
osmc:symbol = red:white:red_bar
Implementing software may choose to use a local database for connecting
osmc:symbol to an icon and to a name, or it can choose to loud read the
value of the symbol tag, if no local naming is available.
A routing software may say: "Follow red bear for two kilometers".
Similar to {{Key|name}}, you can use international naming options too,
for example:
symbol = piros sáv (this is Hungarian)
symbol:en = red bar
----end of ideas---
However, usage of symbol= does not follow this translation method,
because some countries use English naming while others use local naming.
I'd recommend to follow "name:LANG" for consistency.

This seems to have some related documentation in German:
