Extension:SemanticDependencyUpdater

Description
Semantic Dependency Updater (SDU) is a MediaWiki extension that monitors pages for changes in their semantic data. If a Semantic Dependency property is found, SDU will update (null-edit) all pages that have been selected through that property.

The Semantic Dependency property is evaluated as an ASK query. It is therefore possible to define either a list of pages directly or do more complex selections.

It is possible to build a chain of semantic dependencies that will update recursively. Be careful not to build loops!

Installation
Instead of downloading the zip archive you may also check this extension out via Git:
