[OpenLayers-Dev] [Mapbuilder-devel] Who is interested in SLD editing?

[Cameron Shorter]

Lorenzo,
You have sparked my curiosity. Maybe you have identified a user 
requirement which is not covered by OGC specifications.

I'm wondering whether your requirements could be addressed by a WFS or 
Web Coverage Service (WCS).
A WCS can be used to colour a map based on an attribute like population 
density.

Or are you looking for a histogram interface which is displayed as a 2 
dimensional graph which is aggregated from a collection of features (on 
the server)?
