I can see this tool being very useful from a functional point of view. However, the UI is sluggish and there are some unexpected reactions that the SW makes to my interactions with it. I don't believe anything is wrong at this point because I'm certain there will be some training required to understand what the software is trying to relate to me. But from playing with it for 5-10 minutes, I feel that the learning curve is slightly steep, but not unexpected or unrealistic given the value this offers. (IMHO) - Interactions like mouseover on objects (which, I assume, give an overview of the connections without activating it) creates a cluttered/confusing look. Maybe while showing this overview, you fade out all irrelevant objects and markup? - Doubleclick on objects should indicate that it's thinking or doing something. There's no feedback to know I properly activated an object with my intended interaction. - I'm not sure if it's my computer or the UI, but it's extremely sluggish. I'm not sure I'd be satisfied with this experience in a finished product. I know it's a prototype, but still want to mention this. - I might not be the best test subject as I'm not a Java programmer.... or even much of a programmer for that matter. I know this is helpful for someone, but I don't understand how it can be helpful for me. This might be important to be aware of. I hope some of these thoughts help. Overall, I get the impression it's cool. (I'm just not sure why.)
