Hi Michael, thanks for that suggestion, it may well address my concerns. I didn't want to loose the direct graph relationships since that's an integral part of my data model and application. But, as you say, there's nothing to stop adding supporting relationships that aren't navigated when I need

You don't have to loose the direct relationship neccessarily. You can just add a second relationship between the nodes. Just when you need to access the evidence information you need to take the longer route. Michael Jonny Wray schrieb: > Emil, > > thanks for the reply. Yes, I think you've und
