我知道我可以在SubClassOf关系上添加注释：
SubClassOf(
Annotation(rdfs:comment "This annotation is valid")
ObjectIntersectionOf(
ObjectHasValue(:prop1 :instance1)
ObjectHasValue(:prop2 :instance2)
)
ObjectHasValue(:prop3 :instance3)
)
然而，我真正想做的是：
SubClassOf(
ObjectIntersectionOf(
Annotation(rdfs:comment "This annotation is invalid")
ObjectHasValue(:prop1 :instance1)
ObjectHasValue(:prop2 :instance2)
)
ObjectHasValue(:prop3 :instance3)
)
我想要的是创建一个对所有具有关系的对象都有意义的注释：prop1:instance1和：prop2:instance，而不是对子类关系。
我不想为ObjectIntersectionOf创建一个类，因为在我的真实示例中，我将有数千个这样的类。
在下面的文件中运行颗粒2.3.1会产生以下错误：

不，我认为你做不到。OWL2规范允许对本体、公理和实体进行注释，而复杂的类表达式两者都不是（请参见§10注释）。
Pellet与此无关，您会从OWL API FSS解析器得到错误，因为您的本体在语法上无效。
