Thanks, I've understood my problem. I was trying to produce minimal config version to reproduce the bigger problem.
I am using a generic jena rules reasoner and I'm trying to make it work for all named graphs. But it seems like it can be applied only to a model (which as I believe is just a more complex representation of graph of triples, not quads) and I needed it for whole dataset. What I need is basic forward-chain rule reasoner inside each named graph, without no interference this others. I was trying all combinations I could image for assembler config file, but it was just named graph persistence was broke or reasoning not working. Or both. So what do I do? Am I doing something logically wrong and it's not fixable, or I need some more configuration magic, or I need to write some java code to create my own smart dataset implementation with all blackjack and hookers I need?
