Hi all, I'm using with great satisfaction Durus... There are however a couple of use cases that I cannot still handle effectively... Is there any suggestion? 1. DB Bulk data modification. I want to find all objects of type FOO and I want to rename a property without leveraging object graph structures (just to be sure that I do not miss any). 2. Data migration between two Durus instances. I have identical object graph structures in two different databases. I want to get all object in a btree structure on DB "A" and copy them to btree structure on DB "B"... 3. Human readable import/export (XML,JSON) format This would be great and would allow solving also problem 1 e 2... Thank for your help Paolo
