我正在寻找一种方法如何从下面的OWL类中获取rdf属性的值（rdf：about，rdf：parseType，rdf：Description）。
我正在使用JENA java API，但我无法看到任何API来获取这些RDF属性或标记值。
如果你可以帮我解决这个问题，我将很高兴

<rdfs:comment xml:lang="en">An alternative definition for the SpicyPizza which does away with needing a definition of SpicyTopping and uses a slightly more complicated restriction: Pizzas that have at least one topping that is both a PizzaTopping and has spiciness hot are members of this class.</rdfs:comment>
