the entry is
"Open-world assumption (OWA): In a formal system of logic used for knowledge representation, the open-world assumption asserts that the truth value of a statement may be true irrespective of whether or not it is known to be true. This assumption codifies the informal notion that in general no single agent or observer has complete knowledge. In essence, from the absence of a statement alone, a deductive reasoner cannot (and must not) infer that the statement is false. wikipedia "

I cannot find another online definition that seems persistent (university lecturers' slides are not persistent enough!)

I propose we leave the Wikipedia reference.

I suggest adding an amplifying sentence for simple people like me:

"That is, a valid response to a logical query may be: true, false or unknown."
