This is very interesting though it is a relational DBS. I will have a 
look at it.

There seems to be no authentication and authorization. But it could be a 
good choice.

The well known Impedance Mismatch ... this is one reason why I don't 
want to use relational Systems. You can't model such complex Information 
like hotels, crossings, mountain pass roads. In relational Systems I had 
to reduce this to nodes and edges.
