Does the below updated description explain it sufficiently?

This example models the following things:

A thing named God.
A person named Adam.
A person named Eve.
A person named John whose age is 35.
A person named Mary whose age is 25.

A thing named Universe.
A planet named Mars.
A planet named Venus.

This example also models two hierarchies. In the first hierarchy, John and Mary are children of Adam and Eve who are children of God. In the second hierarchy, John and Mary are part of Mars and Venus respectively which are part of the Universe.

Even though John and Mary are in both hierarchies, they are not stored redundantly. To verify this, enable the displaying of each thing's ID via the View Menu. Received on Wed Jul 26 2006 - 20:41:54 CDT
