You can link two entities and store a name-entity "Map" for the 
link. That is you dont store more than one link for a pair of 
nodes but rather as you discover other relations(links, attributes 
whatever you are calling them) you just add that to the map object 
you have for the link.

I have used JUNG (java universal network and graph library) before, 
and it was pretty easy to do these mouse events and so. The only 
thing is, it's a library and written in Java.
