Acknowledgements
The author has to thank his wife Henriette for her endless patience during the last
years, especially for managing our 4 year old foster child Tscharto and accepting my
working during the weekends.
My older son Lukas also respected my eager work and occupies himself with other
topics. My stepdaughter Alex does already her own study with high grades and does
not need any support fortunately.
Thanks to Google for sponsoring the start of the project during Google Summer of
Code 2011. Andrea Aime, an open source developer with excellent skills was acting as
my mentor during this Summer of Code. Thank you again.
Very special thanks for Justin Deoliveira for joining the practical work at a point in
time where the author was powered out. Justin is an excellent open source developer
and pushed to continue the work done during the Google Summer of Code.
In the meantime, the number of mails concerning security work between Justin and
the author is about 400. Justin also prepares the way for getting a paid contract with
OpenGeo[13] to finish the practical work.
Last not least, Justin as a native English speaker reviewed this master thesis and
checked the technical correctness. Thanks again, Justin.
