History:Aspect Model/Reality Aspect
Objects belonging to the reality aspect represent objects you have in the real world and can touch - or at least the template form them. Like: the CD you hold in your hand has a master but for simplicity you can consider this the real object represented by a physical disc in the database. In the same way you can hold a copy of a release in your hands. Those objects are the realization of objects belonging to the ../ConceptAspect.
