As there is no formal representation theory for qualifiers, any categorization of them is unlikely to totally describe their potential usage. I tried to come up with a categorization that reflects property descriptions and a small sample of usage.
So I categorized stated as (P1932) as no information because I see it being used only to provide surface syntax from the source use. The Wikidata value of the statement then provides the totality of the Wikidata meaning of the statement. It is certainly possible that the source provides more meaning than is captured in Wikidata, but that's outside of Wikidata. I see determination method (P459) as mostly providing information to Wikidata as to how much to trust the Wikidata value, which to me makes it a certainty qualifier. peter On 07/19/2018 06:06 AM, Pavlovic, Michal wrote: > Thanks, Peter, > > I agree with You, I was wrong before.
