Thanks for helping!

I want to extract the names and affiliations with the format name, firstname; affiliation1 - affiliation2 - ...

I wanted all the authors, not the first. The unfoldauthors code take only the first 50, but I should have removed these line. I think that my values are in the first element of the array because of the selector $.author here

my $cr = REST::Client::CrossRef->new(
    mailto        => 'd...h',
    spit_raw_data => 0,
    add_end_flag  => 1,
    json_path     => [ ['$.title'], ['$.author'], ],
    json_path_callback => { '$.author' => \&unfoldauthors },
);

The unfoldauthors function is a callback pass to the $cr object. The two json_path arg are used to extract data from the whole json hashref. The data extracted with the second argument is given to the callback function.

This is the output (from the complete example) I'm having now, which is ok, but I'm asking if my callback function could have been made simpler:
