What is an ontology?
A taxonomy is a mapping from names to things. 
Each web service has its own taxonomy, as expressed by its API (WSDL). 
An ontology is a mapping between taxonomies. 
E.g., to solve the problem on the previous page: 
"IP" is an address in one taxonomy. 
"ADDRESS" is an address in the other. 
An ontology must relate "IP" <-> "ADDRESS"
