Make that at least 100 years, or maybe 2500.  
There is a fast-paced but thorough overview of Ontology as 
chapter 2 in John Sowa's recent book "Knowledge Representation".  
He traces it though 20th century philosophers such as 
Whitehead, all the way back to the classical Greeks.  
The picture on the dust-cover is a famous tree-like ontology 
by Ramon Lull, medieval (?) logician.
