That was not the point of my example.  The keys here are in the sense of 
database keys.  Subjects and objects need URIs for linking.

If we have:

   "employeeId":   "1234" ,
   "name"      :   "Alice"

and want the URI to be <http://company.com/employee/1234> then the 
"http://company.com/employee/" has to come from somewhere as does the 
rule for concatenation.

Maybe that happens by something "#" part

{ "#" : { "@gen": "http://company.com/employee/${name}", .. }
