The model is larger but it has limited usefulness. Some may note that Last Name looks very much like an attribute of Person. This may be true in the final analysis, but at this stage, the object Last Name merely exists. Having collected some objects, we can create some sentences that use these objects. It is usually the case that we start here in modeling, but it was fun to look at the existence of objects first.
Person has Last Name.
Person has First Name. Person was born on Date. Country was founded on Date. Other patterns are possible, but not today. They are also assumed to exist.
