Hello,

I 've had an extension that lists article authors in an article, and thought it would be convenient to migrate that to an SMW extension instead, so that the article contributors get stored as special properties, much like modification date. I have registered my special property from the smwInitProperties hook, and I'm adding the author properties from MediaWikis ArticleSaveComplete hook. When the article is being saved this is what I do (slightly simplified, below we save only one property):

        /* page being saved */
$subject = SMWDIWikiPage::newFromTitle( $article->getTitle() );

/* property and value to store */
$property = new SMWDIProperty( '___AUTHOR' );
$dataItem = SMWDIWikiPage::newFromTitle( $authorUserPage );

        /* add property */
$store = smwfGetStore();
$SD = $store->getSemanticData($subject);
$SD->addPropertyObjectValue ($property, $dataItem);
$store->updateData($SD);

return true;

This work pretty well until, I add semantic internal objects. SIO:s on the page will not be stored at all. I guess that means that I'm using the wrong methods here, but I don't know what to try next, so any help woudl be greatly appreciated!

Best regards
Leo Wallentin
