Hello Rafael,
what is really important here is the fact that your package classifies the data within the categorization system Timo developed if possible. Btw.: Awesome that it works so well! This might proove to be a very good alternative to Autonomy (something I've been looking for quite a while).
Once we have a little bit less workload, we would definitly like to take a peek at it and look into ways for integration, unless you are keen on doing it :). I think around 80k AIESEC people will be very grateful if they don't have to categorize all the documents by hand :).
How do you store the classification so far?
