Yes, I am aware that there are people making good use of ontologies.

An ontology is a "snapshot" of the relationships among entities, at a
particular moment of time.  My assertion is that in "life" nothing is
constant, everything is constantly changing.  So, if we wish to reflect
"life" then that snapshot ontology is out of date the moment it is created.
How do we deal with dynamically changing relationships?  That's what I am
trying to address.

Sorry, I wasn't clear.  My point here was to contrast treating semantics
using graphs (which is used to capture snapshots) vice using the field of
complex systems to capture dynamically changing relationships.  /Roger
