That does the trick, thanks.
I was trying to see how many uses of Wikidata qualifiers are contextual (i.e.,
give information about in which context the statement is valid) and which were
additive (i.e., do not limit where the statement is valid).
Of the top ten qualifier properties by usage, five are contextual, three are
additive, and one does not carry world information. The last can be
considered to be contextual, but also might be considered to not carry world
information.
