A subsumptive containment hierarchy is a classification of object classes from the general to the specific. Other names for this type of hierarchy are "taxonomic hierarchy" and "IS-A hierarchy". The last term describes the relationship between each level—a lower-level object "is a" member of the higher class. The taxonomical structure outlined above is a subsumptive containment hierarchy. Using again the example of Linnaean taxonomy, it can be seen that an object that is part of the level Mammalia "is a" member of the level Animalia; more specifically, a human "is a" primate, a primate "is a" mammal, and so on. A subsumptive hierarchy can also be defined abstractly as a hierarchy of "concepts". For example, with the Linnaean hierarchy outlined above, an entity name like Animalia is a way to group all the species that fit the conceptualization of an animal.

包容层次结构是对象类从一般到特定的分类。这类层次结构的其他名称是“分类层次结构”和“ IS-A 层次结构”。最后一个术语描述了每个级别之间的关系ーー较低级别的对象“是”较高级别的成员。上面概述的分类结构是一个包容性的层次结构。再次使用 Linnaean 分类的例子，可以看到，属于哺乳动物等级的物体“是”动物等级的成员; 更具体地说，人类“是”灵长类动物，灵长类动物“是”哺乳动物，等等。也可以抽象地将包含的层次结构定义为“概念”的层次结构。例如，根据林奈的等级划分，像动物这样的实体名称是对所有符合动物概念的物种进行分类的一种方法。
