characteristic of division

characteristic of division

an attribute by which a concept can be subdivided into an array of narrower concepts each having a distinct value of that attribute

e.g. In the following, "number of wheels" and "motive power" are the characteristics by which the concept of "vehicles" is divided. These are shown in the node labels (vehicles by number of wheels) and (vehicles by motive power).

The concepts in an array should be mutually exclusive, having distinct values of the characteristic of division, though lower-level concepts can occur under more than one. For example, hybrids, such as mopeds (mechanically-assisted pedal cycles) are by definition both mechanically powered and human powered. They can therefore be listed as narrower terms of both concepts, as shown below. In some cases it may be desirable to provide explictly for such hybrids, as shown in the examples under array. The scope note should clarify whether a term such as human powered vehicles is to be used for vehicles that are exclusively or partially human-powered.
