ERRORS

 new():
         From Mo::utils::check_array_object():
                 Parameter 'property_snaks' must be a array.
                 Property mediainfo snak isn't 'Wikibase::Datatype::MediainfoSnak' object.
         From Mo::utils::check_isa():
                 Parameter 'snak' must be a 'Wikibase::Datatype::MediainfoSnak' object.
         From Mo::utils::check_required():
                 Parameter 'snak' is required.
         Parameter 'rank' has bad value. Possible values are normal, preferred, deprecated.
