I'm getting acquainted more with Moose and FAMIX and I am not really sure how to proceed (mostly due to lack of documentation and link rot).

What I want to do is add "multiplicity" attribute to FAMIXAttribute.

Now I see an option:

1) create a subclass of FAMIXAttribute

2) add a method.. something like

FAMIXAttribute>>multiplicity

    <MSEProperty: #multiplicity type: #MyFAMIXMultiplicity>

    ^ multiplicity

now Moose can generate models from smalltalk source code and I would like to infer this information.

For example for types, there is MooseImportingContext>>computeTypeOfAttributes

So I'm assuming I would have to do something similar.

And finally, if I want to help the importer and actually write that information into the source code, I would have to add another pragma there... something like

MyClass>>myAttribute

    <MSEMultiplicity: '2..*' type: MyType>

    ^ myAttribute

and then modify the smalltalk importer to be able to recognize this and produce MyFAMIXAttribute instead of the default one.

Am I on the right track? Should it be done differently?

Any pointers appreciated,

Peter
