Hi John, Thanks for showing an interest. The compile error you got was due to the fact that a removed class was still hanging around in the Git repo. I renamed BinaryRelationshipRoles into BinaryRelationshipRole, but the original file was still active in the Git repo. I fixed that. I have been thinking about BDB too for this situation, because the graph database now stores some information about the associated nodes and their reverse lookup. This of course polutes the name/node space. It would be neat to offload this book keeping information to some persistent hashmap, so the implementation is completely transparent to the user. I don't know how nicely BDB plays with Neo4J transactions. Does anyone have experience with this? Another aspect is licencing. I am no legal buff, so maybe someone else can jump in and answer this. Personally, I don't mind adding BDB as a dependency, but it has to work well at the transaction level and licence wise, otherwise it's a no go for me. I would recommend you to start using maven. There is an Eclipse plugin m2eclipse, which allows you to use/maintain Maven projects from within Eclipse. Niels
