I have an interface named PropertyFilter which used to take a Propertyand decide if accepts it or not. And the world was good.

But now the interface changed, so that implementations may choose to add additional Propertys. For example a Customer property might get expanded into Name and Address properties.

I think it is obvious this is not a Filter anymore, but how would you call such a thing?

To clarify: the so called filter is pretty much a method with the signature 

Property -> List<Property>

With an empty List denoting not accepting the Property, a List with exactly the input Property denoting accepting the property and a List with new Properties (possibly including the original one) denoting an expansion.

    Do you already have a name for the method you mention ? It might help us find a proper name for the interface as well.
