Help:$smwgChangePropagationWatchlist

is a configuration parameter that sets the properties that are relevant for property change propagation, i.e. special properties that are relevant for declaring the behavior of a user defined property. This means that changing their values on a property page requires that all pages that use the property must be processed again. For example, if annotations to  for property "Foo" change, then pages using property "Foo" must be processed again. Similarly changes on a category are tracked when its hierarchy structure was changed hereby allowing related entities to be reevaluated.

A special case is  where the declarations are by default made automatically on the category and not properties pages. Change propagation, i.e. the reevaluation of related entities is done when the category hierarchy is being altered through changing category assignments.

The configuration parameter was introduced in. Prior to it was called  .CiteRef::gh:smw:2761 The default setting was last changed with  aiming on further improving property change propagation.CiteRef::gh:smw:2494CiteRef::gh:smw:2776

Changing the default setting
This configuration parameter is not normally changed by users but by extensions that add new types that have their own additional declaration properties. Moreover category hierarchy changes should always be tracked, too. See the "propertyLabels" section of the respective internationalization fileCiteRef::gh:smw:code:propertyLabels for a complete list of property keys and the special properties they stand for that have to be added to set changes to this configuration parameter.
