在Protege中定义OWL属性的合法值范围

Question

如何在Protege中定义仅具有两个合法值（字符串'foo'或'bar' ）的属性？

Answer 1

1. Select your datatype property,
2. Click on "Ranges" and then from the tab "Built in datatypes" select xsd:string .
3. In the tab "Data range expressions" enter {"foo", "bar"}
4. Click "OK"

When you enter a value outside this range, some reasoners like Fact++ will show that as inconsistent, others won't.
