name: Defined Class Description
classification: Good Practice
motivation: If-Then structures are very common and intuitive and this ODP offers the possibility of representing them within OWL DL expressivity
result: The If-Then rule is represented in the ontology and can be used, for example, when adding new classes and performing reasoning: if a class fulfill the If condition, it will have also the Then attribute
aim: To simulate an If-Then of the type: if something fullfills certain conditions, it should have a further given attribute
elements: the important elements are the class that is being used to simulate the rule and the properties that are used in the condition (the equivalent restrictions) and the conclusion (the neccesary restrictions)
