Agreed.

However, there is a problem.  W3C folks seem to lean strongly towards open 
world, whereas database (and most other) folks mostly use closed world and 
negation as failure.

In OW, if Adrian is not in the list of people who work for W3C, you cannot 
conclude that Adrian does not work for W3C.  In CW you can.
