In SysML 2.0, formal/2025-09-03, Page 520:
2. A metaclass from the MOF model is mapped into a MetadataDefinition in the KerML package.

3. A property from the MOF model is mapped into an AttributeUsage or ItemUsage, depending on whether the MOF property type is a data type or a class
4. An enumeration from the MOF model is mapped into an EnumerationDefinition.

In KerML 1.0, formal/2025-09-01, Page 368:
