我知道 owl:Class 是 rdfs:class 的子类，所有 OWL 类都是 owl:Class 的成员。我还知道 owl:Thing 位于类层次结构的顶部。那么 owl:Class 和 owl:Thing 有什么区别呢？ owl:Class 不是在类层次结构的顶部吗？

最佳答案

The most basic concepts in a domain should correspond to classes that are the roots of various taxonomic trees. Every individual in the OWL world is a member of the class owl:Thing. Thus each user-defined class is implicitly a subclass of owl:Thing. Domain specific root classes are defined by simply declaring a named class. OWL also defines the empty class, owl:Nothing.

每个类或对象都是一个'Thing'，如果你懂java，就像说每一个东西都是一个对象，甚至java.lang.Class继承自它
