Hello, thanks to all for the pointers you offered. They were more than helpfull.
So I will give it a try: Grafiscopio seems to be a very good tool to get started with my project . So I will focus first to get my text database into the image. I have to convert the *.org files to *.ston. A way could be via the Leo-editor and Python. But I have to study the *.ston datastructure, to see what is in the box. When this is done I will explore Syre and the Moose-Algos Information Retrieval. But this is a long way to go. I will report. Thanks again and have a nice weekend.
