我知道 owl:Classrdfs: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:Classowl: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
