Notes: The rate of target compared with source configurations.
Object Type Connection Notes
GenericConstraint Class Generalization The TakeRateConstraint defines the ratio between the number of configurations that includes the target elements and the number of configurations that include the source. If several source elements are referenced, it would be the configurations in which all these exist. TakeRateConstraint complements configuration decisions, as the latter defines the rules for actual configuration. TakeRateConstraint defines expected rates of configurations and the set of constraints should be consistent with the configuration decisions. Also, the set of TakeRateConstraints shall be consistent among themselves.
