Software Architectures Assignment 4

From the assignment sheet:

In this assignment, you will refine the Families metamodel from the tutorial, and write a new ATL transformation to create an instance of this refined metamodel:

• Create a new metamodel named ExtendedFamilies.ecore. Create a Family class and a “Person” class. The Person class is an abstract class. Create two subclasses of Person: Male and Female. In the Family class, create a lastName attribute [1..1] of type Estring and a members reference [0..*] of type Person, members is a containment reference. Also add a noOfChildren attribute [0..*] of type EInt. In the Person class, create a firstName attribute [1..1] of type EString, a family reference [0..1] of type Family, a children reference [0..*] of type Person, and a parents reference [0..2] of type Person. The family reference is the opposite of the members attribute in the Family class, and the children reference is the opposite of the parents reference.
• Create a new ATL transformation module named Families2ExtendedFamilies.atl. This transformation should transform each Member to a Male or a Female and set the correct parent/child references. Also add to the above noOfChildren attribute the number of children of each family.
• A new policy requires that the transformation output to also indicate if a family is single-parent or not as an attribute (in addition to the lastName). Add the necessary setup/rules to enforce this. Use the same transformation module as in Q2.

Use abstract rules, helpers and rule inheritance where possible (e.g. A Member2Person abstract rule that specifies how a Member instance is transformed to a Person instance, without going into details about Male/Female or parent/child), and make sure you comment your intentions in the code.
