I don't think you appreciate both: the intellectual challenge and practical 
implications of this discussion.      (02)

>EB: We are talking about knowledge engineering, and in that field, "ontology" 
>>is a term for a model of knowledge.    (03)

To call something an engineering does not make it so. Before Industrial 
Revolution people were building and making things for the most practical 
reasons and in the most practical way they could imagine at the time. That does 
not qualify it as engineering. That was craftsmanship like carpenter, smith etc.
Engineering results in consistent scalable production, which so called 
"knowledge engineering" does not. And it will not until it applies theories.    (04)

One of theories is "Model Theory" which you so casually attached to "model of 
knowledge". This is another example of pseudo-engineering. In fact data 
modeling is only an engineering discipline withing a particular well 
axiomatized relational model with all available mathematical and technical 
tools. Likewise software engineering is only engineering within well developed 
calculus translated into true programing languages - all other "creativity" in  
software industry has not yet reached the level of engineering, despite 
considerable wealth created, which is not a proof of soundness (at least to me).    (05)
