So how do I (that just understand the surface) explain this to the business people in the organisation? :-) Does anyone know of a publicly available presentation, or such? (Slideshare?) Life is interesting. Interesting post.

The paragraph where you point out that you are using CWA vs OWA as shorthand for the "relational approach vs. (open) semantic Web approach" is more accurate, but using "relational approach" to characterize the other side is still misleading. I think you have good arguments against attempting to build THE model, one huge ontology "to rule them all" (as some say). As you point out, the CWA applies specifically to interpreting the absense of a proof; it does not limit how you build or extend the schema/ontology. The OWA could be applied against a relational data model: run the query and if you get no results, answer "maybe" (a bit of a simplification, but that's the general idea). Cyc (www.cyc.com) has been applying the OWA since the mid 80's, but I think few would say it has been a success.
