A small framework allowing business object collaborations and instance variables to be declared declaratively Ruby On Rails style, resulting in a domain model kind of matching the style of the Streamlined Object Modeling book. Relationships between objects are reified as objects themselves and doesNotUnderstand: is used to intercept messages and answer them dynamically. Unit tests and Mocks are included as samples. Package requires at least PackageInfo-Base-avi.20 to avoid getting an error on the Monticello post install script.
