Using polylang, how can I see which post is the “original” and which are the “translated children”? [closed]

by

I am using Polylang. It is not obvious to me how the relationship between posts are established. I can switch between different language versions of the same post, and I can tell that they’re (obviously) different posts in the database.
But I can see how Polylang establishes and maintains that relationship. I assumed that there was some meta-value, but that’s not the case.
Does anyone have any insight?

Initially, I’d like to know this, because I need to create a publish flow where translations aren’t accidentally published before the “original”.

polylang stores translation in a taxinomy but it’s better to access them with the polylang object like that : 

// test if the plugin polylang is present
if (isset($GLOBALS["polylang"])) {

    $translations = $GLOBALS["polylang"]->model->post->get_translations($post->ID);

    // $translations contains an array with all translations of the post

}

all translations are interconnected then there is no parent translation. if you want to find the first created post you can search the lowest ID or sort by publication time.
