[OSGeo-Discuss] Thematic Mapping Engine as Open Source?

I agree that there might be some linkages to the OSGeo Cartographic 
Library Proposal:
http://wiki.osgeo.org/wiki/OSGeo_Cartographic_Library
There are some interesting bullet points under the Functionalty section 
that relates to thematic mapping.

TME should be able to read simple features (boundaries for 
choropleth/prims maps) in the most common formats.
So far only Well Known Text (WKT) is supported, but I would like to add 
GeoJSON support, and possibly WFS Simple.
TME also needs centroids to place proportional symbols etc.

Features could be fetched from one source (e.g. MapServer or GeoServer) 
and statistical data from another source
(like UNdata) - and then merged through geolinking.

There is a need for a thematic mapping standard, - or a thematic mapping 
extension to SLD/SE.
There are a few proposals around:

1) Dietze, L. and Zipf, A. (2007 accepted): Extending OGC Styled Layer 
Descriptor (SLD) for Thematic Cartography - Towards the ubiquitous use 
of advanced mapping functions through standardized visualization rules.
