Dear all,
 
I think that there is usually a misunderstanding on the meaning of CWA vs. OWA:
 
It is  because of that a discussion might be extended based on implicit understanding of the semantic possibilities of these two concepts.
 
for the cases like "...Therefore facts not stored in the database and not 
derivable from the existing data 
are considered false in the CWA and unknown or possible in the OWA.... "

My argumentation: 
1. in OWA, negation is not "considerated" at all. Or in another 
word, negation is not cognitively available in the mind, and subsequently not 
available in semantic expressions produced/organized in the mind. 

2. if negation appearred in the background of OWA, it can not bear intended semantics at 
ontological/existance level. It will be a pure notation instead of a complete 
concept with both notation and intended semantic.  limited references :
