在构建本体时，应该除了定义类以外，还需要实例化这些类。示例代码如下：

定义一个Classes类

Classes = [ "Person", "Animal", "Vehicle", "Food" ]

实例化这些类

Person = Classes[0] Animal = Classes[1] Vehicle = Classes[2] Food = Classes[3]

定义类的属性和关系

Person_hasName = "has name" Person_hasAge = "has age" Animal_hasSize = "has size" Vehicle_hasColor = "has color" Food_isEdible = "is edible"

将属性和关系与相应的类属性关联

Person_hasName_property = { Person_hasName: "string" } Person_hasAge_property = { Person_hasAge: "int" } Animal_hasSize_property = { Animal_hasSize: "int" } Vehicle_hasColor_property = { Vehicle_hasColor: "string" } Food_isEdible_property = { Food_isEdible: "bool" }

定义类之间的关系

is_a = "is a" has = "has"

将类之间的关系与相应的类属性关联

Person_is_a_Animal = { is_a: Animal } Animal_hasPerson = { has: Person } Vehicle_is_a_Animal = { is_a: Animal } Food_is_a_Animal = { is_a: Animal }
