It seems like $type defined by \Jkphl\Micrometa\Domain\Factory\IriFactory::create($type) on line 332 can also be of type object<Jkphl\Micrometa\Domain\Item\Iri>; however, Jkphl\Micrometa\Domain\Factory\IriFactory::create() does only seem to accept string|object<stdClass>, maybe add an additional type check?

        return strlen($type->name) ? $type : null;
