Clyde, Questions on RDF may not be asked but I think it's good if you can have an idea of XQuery. Some questions on this concept may be asked. Please note that I've used "may" for both the topics, so it's not guarenteed that these questions will not be asked. If you have time, just have a reading before going to the exam. Good luck, Rakesh.
