I'd say forget about classes and make your objects big bags of properties 
(attributes and relationships).  The main advantages of classes for 
object-oriented programming -- code reuse and type-safe polymorphism -- 
don't even apply to simple information representation, so why pay the costs 
of a class structure if you don't receive any benefits?

  There exists an entity A.
  A is human.
  A is male.
  A is married to B.
  A is a biological parent of C.

That's not so hard, is it?

All the best,
