. If the rule 1 for class inclusion was to apply, the relationships would not be considered as redundant because | Concept |
|---|
| ShowParts | term |
|---|
| t | 74905005|Ethylmorphine (substance)| |

|
is not a subconcept of | Concept |
|---|

, the rule 2 actually compares the anonymous concepts for subsumption, i.e. | Concept |

. Therefore, the inherited relationship is redundant and can be removed from the NNF. Their relationships and property chain can be demonstrated in the following diagram.
