Possibility to create/edit a custom meta tag?

[giovanniciriello]

Hi.
I'm looking for a way to write and read a custom meta tag in my epub files.
For example:
$epub->set("publishYear", "2017");
$epub->get("publishYear");

Thanks in advice

I solved my problem. I simply created a method into epub.php like this:
public function customMeta($downloader=false){ return $this->getset('dc:customMeta', $downloader); }
