Instances抽象体这些特质或质量，和任何以物理媒介化身的特质/质量不同。抽象 的实例在意义上，可以说是像数学物体如集合和关系般存在，但是它们不能没有任何物理编码或化身便存在于特定的时间 和地点。
 实体The universal class of individuals. This is the root node of the ontology.
 可继承的关系这是一个 Relation 类别，它的特性可以是 通过 subrelation Predicate 把特性在类别的层次结构承传下去。
 基于PPP的经济估值PPPBasedEconomicValuation is a class of relations used to state international economic information in U.S. dollar amounts. The U.S. dollar amounts are derived from Purchasing Power Parity conversions of economic totals (e.g., GDP) given in local currency. This contrasts with a method of conversion based on currency exchange rates. The PPP method is used by the CIA World Fact Book for the purpose of presenting economic data for all countries covered. Their basis for PPP dollar price weights is the UN International Comparison Program (UNICP) and the work of Professors Robert Summers and Alan Heston of the University of Pennsylvania.
 谓语Predicate 是一个作句的 Relation，这个 Relation 的每一个元组都是物体有限、有序的的句子。一个特定组员是一个 Predicate 的元素这事实，由 '(*predicate* arg_1 arg_2 .. arg_n)'来表示， arg_i 是关联的事物。在 BinaryPredicate 的情况下， 可以读成 `arg_1 是 *predicate* arg_2' 或者 `arg_1 的一个 *predicate* 是 arg_2'。
 四元谓语这是一个需要四个参数的 Predicate Class。
 四元关系QuaternaryRelation 连接四个项目。 QuaternaryRelation 的两个 subclass 是 QuaternaryPredicate 和 TernaryFunction。
 关系这是关系的 Class。现有三类的 Relation: Predicate， Function 和 List。 Predicate 和Function 皆表示有序的n元组集合， 这两个 Class 的差别在于 Predicate 包括组成公式的运算符，而Function 则包括组成 术语的运算符，而一个 List 却是一个特定的有序n元组。
