In the real world entities appear to be more solid. All of the context and names for entities used in bare facts are choosen by the user. Nothing is predefined in Factotum except the form of the fact. In addition two other parts may be optionally added to a bare fact. The first is a marker character which defines what kind of fact this is, the other is a citation reference.
Facts come in two flavors informal and formal .
Both formal and informal facts start with a single word that is the subject. Informal facts are comments about the subject which can be carried along with the entity but are not a part of the formal description of the entity. For example, the folowing informal facts could be added to our entity definitions of Adam and Eve. The pink text is commentary. Finding citations to support these informal facts may be difficult.
