This looks very interesting.. but i'm not sure what it is. A tutorial will be very much of help.
As far as I can tell, it is a model that supports storing entities and their relationships and the history of all entities in a predefined set of tables (5 tables).
Entity relationships are not done by using a simple reference but by using queries. There is also the concept of successors and predecessors.
The example model is pretty big for beginners with this framework. Maybe a model with 3 entities (Customer, Order, OrderLine) will be more clear.
But very interesting.
