Hey, I got an ontology question.
Classes are, in semantic web framework and their foundations like
Description Logic, if I'am not wrong, something like a lohic predicate that
intensionaly or extentionaly defines the properties of their instances.
They are usually not qualified, but in Wikidata, as of now they are
properties like the others, who can also be qualified.
So the question is : could we use qualifier on classes to add predicates on
the class definition ? For example if
<George Bush> is an instance of <United States President> [<from> 1980
<to>
1984] (random years), this would mean that the instanciation add some
predicates on the other predicates we have on the <president of the united
states> ?
Just a random thought, I just realise I just qualified the instanciation,
not the class itself.
