    ),
    array(
        'name' => 'url',
        'id' => 1,
        // Add domain to relative URLs
        'apply' => function($match, $crawledUrl) // <== 2nd use case
        {
            if (!stristr($match, 'http')) {
                return $crawledUrl . trim($match, '/');
            }
            return $match;
        },
        'validate' => function($match, $crawledUrl) // <== 3rd use case
