UML is handy in that it's widely understood, but it's got a lot of closed-world assumptions in it. e.g. in UML, if you say the Person class has a gender M/F property and a sibling property, then somebody else can't derive a brother property and a sister property, because the list of properties in a UML class is sorta closed. So it's great to compare OWL with UML, but let's also be careful to contrast it. -- Dan Connolly, W3C http://www.w3.org/People/Connolly/
