Actually, in Datomic, the namespaces don't have any special meaning for the 
database itself--you can choose to use whatever namespace (or even no 
namespace)! Using namespaces is a convention to help you keep track of 
which attributes belong to which entities.

We don't use a separate model layer for our systems--the Datomic APIs are 
actually pretty rich when it comes to manipulating the system, between the 
transactions as data and the entity API.
