IsInstance

Returns OwlInstance if the argument rdfsResource is an actual active instance in an active model. It returns 0 in all other cases, i.e. this could mean the model is already closed, the instance is inactive or removed or the session is closed. It could also mean it represents a handle to another resource, for example a class, property or model.
