"A metaclass in Wikidata, e.g., watercraft type (Q16335899), ship type (Q2235308), or second-order class (Q24017414), is an entity that can have other entities that are an instance of (P31) of it that in turn can have yet other entities that are an instance of (P31) of them. All metaclasses are thus classes. All metaclasses are implicitly an instance of (P31) metaclass (Q19478619). These implicit instance of (P31) statements are not all observable in Wikidata. Only a very few metaclasses should be be explicitly an instance of (P31) metaclass (Q19478619). Most metaclasses are fixed-order classes, e.g., their instances are classes of individuals, and should be an instance of (P31) an instance of (P31) fixed-order class (Q23959932) such as first-order class (Q104086571), second-order class (Q24017414), or, less commonly, third-order class (Q24017465)."
