Help:Automatic query update

Currently Semantic MediaWiki (as of 1.9.2 and by the time of writing this help) does not support a "real" auto update (aka "smart" queries*) that would refresh the results of pages that include the query results but to mitigate this shortcoming the following scenarios are supported:

"smart" queries where an algorithm is used to find a data diff which would trigger a refresh of only those related subjects and its queries within the store (and hopefully invalidates the MediaWiki html/parser cache as well otherwise it prevents the page from displaying the updated results).

Manual refresh/store update
From Semantic MediaWiki 1.9.0 using  ("refresh" tab not  key) in combination with   allows to refresh (update the store) of a single page manually.

Selected automatic refresh
If a manual refresh of a page is not an option, you could use the  parameter in "rebuildData.php" maintenance script (introduced with Semantic MediaWiki 1.9.2) to select a group of pages (using a query condition) that are refreshed on a repeated schedule (through a job etc.).
