Can I confirm that I'm right in thinking that one cannot use "role expressions" in OWL DL/Lite, i.e. I can't say things like (playing fast and loose with syntax): Person AND all (inverseOf hasParent) Doctor but instead would have to define a new role hasChild == inverseOf hasParent and then use that role. (Note that I'm quite happy *not* being able to do this as it makes the data models much simpler....).
