5 From their site: Validity is a framework (Validity) and a WebObjects application (Validity Modeler) which combine to provide a powerful data validation engine and validation rule modeler. Using an EOModel as a reference point, one may assign rules to the various attributes of the entities. One may choose from any of Validity's predefined rules, or write his/her own rules in Java. The rules are stored in the Validity model file (Validity.model) inside the corresponding '.eomodeld' wrapper.

7 Validity has two parts: a framework and a tool (ValidityModeler).
8
9 Use tool to add validation rules to your .eomodeld.
10
11 The framework hooks into your EOs' validateFor[[Insert>>Delete]] methods.
12
13 Framework engine applies rules at runtime and throws an exception if a rule is broken.
14
15 Using Validity results in less validation code in your own enterprise objects.
