Change propagation
Some insights as what requires change propagation to be successful

Changes to a value annotation (respectively a page or template that contains an annotation) and its propagation depends on how its is included or annotation are made available.

Transcluded content[edit]

Content that has been transcluded using {{:myPage}} (or as template {{myTemplate|param=foo}}) into a page (including its value annotations) requires that MediaWiki's "refreshLinks.php" maintenance script has been run first before changed values are made available to the Semantic MediaWiki backend (and hereby possible dependent queries and its result display).

This is even more important for use cases where {{:myPage}} itself transcludes data from a template and requires updates. The job queue is expected to be scheduled appropriately to ensure updates are dispatched within a short period of time to avoid a large backlog.

Property type and/or constraint changes[edit]

The approach on how changes are propagated has been revised with Semantic MediaWiki 3.0.0Released on 11 October 2018 and compatible with MW 1.27.0 - 1.31.x.1.
