In the Concept Modeling interpretation of UML, subsetting a property creates a subproperty when the subsetting property has a different name than the subsetted property (see section section Subproperty). UML provides a {subsets} constraint that asserts that the values within a subsetting property are also in the set of values within a subsetted property. The concept modeling profile Concept Modeling Profile interprets a subproperty as a subsetting property that has a different name.
To add a subproperty
Drag and drop a subsetted property
(
, e.g.
, “consists of” from “Soccer Team”) onto
has children, onto a property
(
, e.g.
, “composed of” from “Futsal Team”)
has john.

The property is owned by the class at the opposite end of the association. Additionally, the target can have the same name as the source, or can be unnamed. The resulting redefined property's multiplicity is adjusted to conform to the multiplicity of the dragged, subsetted property.

When you have multiple subproperties on the same generalization, the following window will appear when you are trying to remove the subproperties. This dialog allows you to choose the subproperty you want to remove. It does not remove the subproperties at once, it lets you choose one at a time.
