[OSM-dev] Standard for Map Key

[Peter Wendorff]

Hi,
as far as I know all map keys are created by hand.
I'm not sure what you refer to exactly, but basically I see two things
which would be great to have:

1) some kind of "standard" to retrieve a map key for a given tile set;
e.g. tile-URL is tile.openstreetmap.org/{z}/{x}/{y}.png, then search for
map key information (in a structured format, not html) at
tile.openstreetmap.org/mapkey.xml
As far as I know there is nothing like that yet.

2) it would be really great to have some automatic map key generation
out of the style files. For Mapnik that's incredible ugly as mapnik does
not have any semantic connection between e.g. highway casing, fill and
label. For CartoCSS (which is used since a while for the default style)
this might be possible in parts.
In any case it would require additional information like which label to
use for a particular feature in the map key, which items should NOT be
displayed (as Tom mentioned) or in which order items should be displayed.

regards
Peter
