Hello Mrs Schweiger,
I am a german developer who works quite a long time with ADAPT (mainly with the framework, less with AT). Possibly i can give you some hints. I am also interested in general exchange of experiences.
If you are also interested, please contact me under email@example.com (it's a temporary emailaddress because of spam protection). Then I can send you a pm.
PS: Its not a hoax: My lastname is the same as yours, except the "t" at the end ;-)
