Wordpress _blank

Question

I would like to add a target="_blank" to the data-link-url line of Code below. but I don't know where or how to add it. I keep breaking the code when I try.

I would simply like the link to open in a new tab.

Any help would be great.

    <a 
        href="<?php $content->link(); ?>"
        <?php if (!empty($meta->project->url) && !empty($meta->project->label)): ?>
        data-link-url="<?php echo esc_url($meta->project->url); ?>"
        data-link-label="<?php echo esc_attr($meta->project->label); ?>"
        <?php endif; ?>
        data-largesrc="<?php echo $t->image->resizedImgUrl($content->get_origImage(),500,370);  ?>"
        data-title="<?php echo esc_attr(get_the_title()); ?>"
        data-description="<?php echo esc_html(get_the_content()); ?>">
        <?php $content->img(250,185); ?>
    </a>
