Attached please find a draft conceptual model of RZ_LGRs application. I tried as exhaustive as I could in uncovering the technical issues that surround the application of the RZ_LGRs, and I am sure there are still issues left uncovered.,You can comment on it, add/ omit elements which you think are necessary/unnecessary. The conceptual model is a complementary piece to the working document under development. It can be integrated seamlessly. 

Kind regards,
