Hi all, I'm working with a new human rights NGO that hoovers up a lot of information about events, victims, perpetrators etc in a number of unpleasent countries. Most NGO's tend not to manage this information very well so we are looking to do better by looking at how people in policing/intelligence roles do this. We've come across i2 Analyst's Notebook and the Sentinel Visualizer products and it seems perfect for what we do but it's eye-wateringly expensive for a charity. Can anyone recommend anything that is opensource or alot cheaper that fullfills many of the same functions? Many regards.
