Statements
A fixed-order class in Wikidata, e.g., watercraft (Q1229765), watercraft type (Q16335899), or second-order class (Q24017414), is a class whose instances are all of the same order, e.g., all not classes (a first-order class (Q104086571) like human (Q5)) or all classes whose instances are not classes (a second-order class (Q24017414) like ship type (Q2235308)).No class should be explicitly an instance of (P31) fixed-order class (Q23959932); instead use one of first-order class (Q104086571), second-order class (Q24017414), third-order class (Q24017465), or very rarely one of the other subclasses of fixed-order class (Q23959932).
