Property declarationHelp:Outdated properties

Outdated properties (a.k.a. orphaned properties, those with zero annotation references) 1 are expected to be removed after the rebuildData.php script 2 has found no remaining references.

Sometimes the "zero" reference displayed in Special:Properties can be deceiving which is also why some properties remain in the list 3 because they still hold a reference beyond the normal "annotation" trait which includes:

  • Pre-defined properties are excluded from the removal procedure and are non-moveable4
  • User-defined properties marked with zero references but have been explicitly declared (type, description etc.) are not categorized as outdated (the user showed an intend to keep the property)
  • If the QueryDependencyLinksStore has been enabled then properties used as printrequest label are being taken into account when validating whether a property has remaining references or not
