During reconciliation of the HDF ballot the issue came up regarding the term Focal Class. As I understand it, at one point a decision was made that all state transitions, as they tied to trigger events, would occur on Acts, not Roles or Entities (I'll ignore Managed Participation). The status Code on Roles and Entities would tie to business process, not trigger events. Thus, as an example, a nullification of a Patient role would be communicated on a registration act rather than the role itself.

Do people agree with this, or did I understand something that wasn't correct?

It seems this term is used in two ways:

  • The entry point to an RMIM
  • The class(s) with state changes related to the trigger event.

These are two different things and we should have different terms for them.
