Ontologies And Cost

Furthermore the authors are not aware of any proof that completely representing a domain is a cost efficient solution to any business problem.

Just a sentence I wrote in a publication I work on. Re-reading it I realized that this is actually a shocking statement - does this mean that all old fashioned attempts to build ontologies are wasteful? Or is there this proof but I just don't know it?

Actually I think that this only applies to really old fashioned attempts to build an ontologie - those that actually somehow strive for completeness in representing a domain and lose track of the task an ontologies is supposed to be used for. In general this kind of thought is just another reminder that the "an ontology is a formal conceptualization of a domain" definition is incomplete - any actual ontology is an artifact created for some purpose. Forget that and you'll never finish modeling and end up with something that you can neither verify nor validate.
