Technologies are provided for creating and using template constraint expressions in constraint-based systems. Template constraint expressions can be created that can be used to define multiple usages of a same constraint rule in a configuration model. Using the template constraint expression, the constraint rule can be translated once and used multiple times as different instances of the rule are activated. Updates to the rule can be made to the template constraint expression and applied to all of the related instances. Constraint expressions can be created based on the template constraint expression. Configuration rule definitions in a configuration model definition can be parsed to create graphical representations of the configuration model definition. One or more of the graphical representations can be used to create a template constraint expression. Multiple object instances in the configuration model can be identified that satisfy matching criteria of the template constraint expression.
