The Rate Table element provides a graphical representation of the rate expression. It is accessed from the Data Types pallet.

The steps below describe how to implement the logic described in Example. For brevity, some steps (such as the best practice of creating description rule attributes) are omitted.

Create a `Person` rule class

Create a rule class named Person, and add the following attributes:

totalIncomeTimeline (Number, made into a Timeline); and
isEligibleTimeline (Boolean, made into a Timeline).

Note: No derivations will be given for the totalIncomeTimeline in this example. This attribute is assumed to be populated from an outside source (such as evidence).

Implement rate retrieval logic

Implement the derivation of isEligibleTimeline to retrieve the required rate data and compare it to the person's total income.
