Response format A:

[
  {"id_str":"1","id":1,"last_name":"Johnson","date_of_birth":null,"display_name":"Stephanie Johnson","first_name":"Stephanie"},
  {"id_str":"2","id":2,"last_name":"Black","date_of_birth":null,"display_name":"Joe Black","first_name":"Joe"}
]

Response format B:

[
  {"patient":{"id_str":"1","id":1,"last_name":"Johnson","date_of_birth":null,"display_name":"Stephanie Johnson","first_name":"Stephanie"}},
  {"patient":{"id_str":"2","id":2,"last_name":"Black","date_of_birth":null,"display_name":"Joe Black","first_name":"Joe"}}
]

And the mappings are ...

    RKManagedObjectMapping *patientMapping = [RKManagedObjectMapping mappingForClass:[Patient class]];
    patientMapping.primaryKeyAttribute = @"id";
    [patientMapping mapKeyPathsToAttributes:@"id_str",@"id",
     @"first_name",@"firstname",
     @"last_name",@"lastname",
     nil];
    
    [objectManager.mappingProvider setMapping:patientMapping forKeyPath:@"patient"];
    
    RKManagedObjectMapping *patientSerializationMapping = (RKManagedObjectMapping *)[patientMapping inverseMapping];
    
    [objectManager.mappingProvider setSerializationMapping:patientSerializationMapping forClass:[Patient class]];
    
    [objectManager.router routeClass:[Patient class] toResourcePath:@"/patients" forMethod:RKRequestMethodPOST];

With format A, the mappings just worked. With format B, the extra level of encapsulation -- as in { "patient" : { "id" : 1, "first name" : "simon", … } } -- didn't quite work and I had to look for key paths like patient.id to get to the actual values.
