Hello! I am willing to develop a spatial extension for Apache Derby database. This will enable derby to store and manage geospatial data in the way of OpenGIS standard: Simple Feature Access. That means some geometry types and build-in functions should be added to the engine. After that, we can use Derby as a geospatial data source, at the backend of a portable mapping software or a web mapping site.
I will do this in the later three months. So I just post this to the mailing-list to get some suggestions from you.
