xquery and geospatial request

[Sébastien Geindre]

And what do you think about such architecture for geospatial web 
services with GML data :

Cocoon server <=> eXist Database with Java extension implemented with 
JTS (Java Topology Suite)

TigerLogic database does not seem to be opensource....
> A client seems happy with the Java Topology Suite and
> GeoTools, which includes a GML parser.
