Person Entity Model

The Person Entity Model defines a framework for the modelling of person-related entities like organisations, teams and other groups - and of course persons. It includes a generic model for affiliation, which shall be introduced here.


We start with an obviously simple (read: small) set of person entities:

Each of these entities can define a number of roles which affiliated entities can have:

Now we link the respective entities to the roles, which defines an already pretty complex relationship network:

Some of these relationships define a hierarchy, while others don't:

This hierarchy defines ancestor paths among the person entities:

If we remove the roles, this becomes more obvious:

Now we can make the actual "hierarchy" visible by moving each entity to a certain "hierarchy level":

As you can see, "Person Y" belongs to two different organisations here - with two different ancestor paths.
