Hi,
What I did is just deleting the restriction with the following script :
DatatypeProperty dp = m.getDatatypeProperty(URI+element);
List<Restriction> restrictionsToRemove = new
ArrayList<Restriction>();
ExtendedIterator<Restriction> i = m.listRestrictions();
while (i.hasNext()){
Restriction r = i.next();
if (r.onProperty(dp)){
restrictionsToRemove.add(r);
}
}
for (Restriction r: restrictionsToRemove) {
r.remove();
}
dp.remove();
but, it resulting an empty IntersectionClass since it only remove the
restriction. I havn't tried any ways to remove the empty IntersectionClass.
Maybe any of you have an idea how to remove it.

What have you tried so far? It's easier to help you debug your code if
you actually show us the code!
