If no $wgMetadataWhitelist is defined the extension will return the function early and leaving it pretty much in a disabled state.

I think the basic function (for category and language links) should work either way. Not everybody needs $wgMetadataWhitelist for templates.

Or even better, for consistancy, put a default value in it. That way people can use it right away and don't need to pick a fancy name themselfs.

I propose to change line 26 from
$wgMetadataWhitelist = '';

to

$wgMetadataWhitelist = 'MediaWiki:MetadataWhitelist';
