In addition to this the extraction mechanism should also cover various
coding styles which is slightly different than representing the same graph
in different ways.

For example, If I want to associate a property to a class in OWL, there are
atleast two ways of doing it- 1. by using rdfs:domain in the property
description or using cardinality restriction in the class definition. Now,
If I want to list all classes and their corresponding properties, I have to
write atleast two queries/templates. To further complicate the situation,
there are multiple ways of specifying owl:Restrictions.
