Things, events, relationships, and so on seem to me to be
the bottom levels, or near there, while novel concepts defined
on top of these kinds of objects are the higher level ones.
I base this kind of thing on the definition of a "generalization"
of a component - A is more general than B if A has fewer 
properties than B, and if every property A has is also a
property of B.  So B has every property of A and then at least
one more, making B a specialization of A.  

Take a database table with Name and ID as attributes.  Another
table having Name, ID and Phone Number would be a specialization
of the first, and would have to be placed lower on the lattice.

JMHO,
Rich
