I have a Meeting Object:

Meeting{id, name, time, CreatedBy, UpdatedBy}

and a

MeetingAssignee{id, MeetingID, EmployeeId, CreatedBy, UpdatedBy)

Meeting, as Aggregate root, has a method AssignEmployee.

I was about to pass in the current user to the Meeting object as I call AssignEmployee, so that it can update its audit fields accordingly.

But this doesn't seem right - is it? Obviously I can keep the audit fields public and change them later - perhaps at service level?

What is everyone's else preferred method for updating these fields?

Please note: We are not using Nhibernate, but a custom ORM which does not have anything automatic in place.

Thanks.
