Two almost identical OneToOne in Entity, custom join annotation?

There are too many things I don't quite get in your solution to give a good answer but just some thoughts.

I see two problems with using one-to-one references.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
