This could be two different questions:
(1) How do I force every page to be purged, so that inline queries do not come
from the cache but are recomputed?
By default, MediaWiki clears its caches whenever the file LocalSettings.php
was modified. To clear the cache once, just touch this file. To switch off
caching completely, you can add the line
$wgCacheEpoch = date("YmdHis");
at the bottom of your LocalSettings.php. This should be done only on not so
large wikis.
(2) My articles contain semantic annotations but they are not found in
semantic searches. What can I do?
This can happen when article texts are imported into the database without
being properly created in the wiki, when attributes have been used in an
article before they were defined (with a proper type), or when annotations
are imported into articles via templates and have not been saved since the
template was annotated. The factboxes will always show what is currently in a
pages text. To see what is really in the database, you can look at the RDF
feed.
Similar problems appear in MediaWiki with categories (e.g. templates that
include category statements will not affect categorisation until the
categorised articles are saved again, even though the category is printed
below the article). To fix this, you need to run a maintenance script that
touches every problematic article. MediaWiki supplies the script
maintenance/Rebuildall.php to do this. This process can take some time to
complete.
Hope this helps,
