As mentioned in Chapter 8, Manage Indicative Data: Provisioning Outsourced Benefits and Payroll Systems, the IndicativeData noun has "swiss-army-knife-like" utility for many HR system integrations. UserAreas make it easy to extend. However, it is not intended to be a complete set of "HR master data."

This broad, flexible specification is provided in the sections that follow.
