Answer 1

If you use the current development branch (at the time of writing this feature hasn't been merged back to the master branch) you can use metadata to access the parent object during the mapping process:

@metadata.mapping.parentObject

So you can add a mapping:

@"@metadata.mapping.parentObject.UserID" : @"userId"
