| | 19 | EXAMPLE Typical uses of this template is in classification of classes that are used by particular |
| | 20 | entities or which are defined in domain standards. No restriction on the order of the |
| | 21 | classes is imposed. As an example of classification of a second-order class by a third-order class, |
| | 22 | consider “the types of drill string belong to the drilling domain”. This could be expressed by |
| | 23 | !ClassificationOfClass(Drilling Domain Class, Drill String Type) |
