Handling changes in boundaries

Institutions and or individuals are associated with a boundary. Thus a change made to the boundary will result in changes to these associations.

There are three things that can happen:

A new geographic boundary is created and new institutions/individuals are added to it

This is a pretty easy case to handle.

A new boundary is created from one or more existing boundaries

This is what usually happens. In this case:

  • A new boundary is created
  • The new boundary is associated with an existing parent boundary.
  • Some of the existing institutions and individuals association is changed to reflect this. They are associated with the new boundary.

A boundary is deleted

This going to happen rarely, if ever. The institutions and individuals associated with this boundary will not cease to exist. It is equivalent to a boundary being completely merged with another. Thus the associations will now be with the other boundary.
