ODM12 — Distinct associations, ownedAttribute associations

Distinct associations, ownedAttribute associations. In 16.2.2 (Class and Property - Basics), in the paragraph below Table 16.6, there is the sentence " Note that UML ownedAttribute M2 associations are distinct, even if ownedAttributes have the same name associated with different classes." What are "M2 owned attribute associations"? In the case of M1 properties, properties with the same name may be on different classes, but if they inherit from the same base class where a property of that name is introduced, then they are the same property from OWL's point of view. There is usually no no need to translate to unique OWL properties, just restrictions. See next issue.
