This amendment to Rec. X.720 | ISO/IEC 10165-1 covers the generalization of terms so that these terms and concepts can be reused in the General Relationship Model (see Recommendation X.725). It is intended that the generalization in terms does not change the semantics in the Management Information Model (see Recommendation X.720). The general approach for the specified terms (characteristics, inheritance, hierarchy, multiple inheritance and specialization) is to remove the term “managed objet class” and use the more general term “class”. It is beneficial if the General Relationship Model does not have different terminology for the same general concepts as the Management Information Model.
