You can try to set the $smwgEnabledSpecialPage configuration parameter like as follows in your LocalSettings.php:

$smwgEnabledSpecialPage = array( 'Ask', 'BookSources' );

Yeah, that should be it. Great @jaideraf I would not have thought about this setting in the first place. Thanks for this re-vaccination.

Tried this; did not help.

:+1: Very good observation (it should be Booksources because of [0]).

See comments below.

with SMW:on when invoked on Special:Book sources (via Project:Book sources)

I'm guessing those "(via Project:Book sources)" are maintained as messages where SMW in general is to skip parsing of content that is injected via a Message object [1] (avoids a performance penalty otherwise each message would require us the inspect a message and its text body in case the InternalParseBeforeLinks hook is called).

Nevertheless, I changed the process in #2211 so that in case a special page is enabled in smwgEnabledSpecialPage to be allowed to parse [[ ... :: ...]] annotations including those with a [[SMW::on]] marker.
