All aspects of object orientation (encapsulation, inheritance, and polymorphism) apply equally to class members and methods. In OWL/RDF we have class inheritance but we don't have the structure of a class such as we do in programming languages. The triple of S-P-O is a very simple structure, so there isn't any structure to encapsulate nor is there structure to use differently in different contexts (polymorphism). I mention this not to negate anything you have said but because some of the things you said about OO and OWL/RDF aren't completely clear. So to be clear, when we define restrictions on a class (e.g., that some class B has a restriction of predicate p), that restriction is not inherited on a subclass B1 of B. True?
On the other hand, when we define a predicate p with a domain of A, any subclass A1 of A will apply equally as a domain of p. True? These two contexts are different.
