This use case is too obvious that it might not be obvious to cast it as a
use case, but I'll try.

** ETRI-UC1: Filling the holes of OWL

When building ontologies using OWL, we usually come up with such relations
or classes that are difficult or impossible to express in OWL, which creates
vocabulary holes in the ontologies. The most representative hole is the set
of relations that can be defined by chained properties[1][2]. For example,
with OWL alone, you cannot describe "uncle" relation, which is the
composition of "father" and "brother" relation, into the family ontology.
With rules, it's trivial to describe the relations defined by chained
properties. As such, RIF will be an essential semantic web language that
complements and extends OWL.
