Numeric and Boolean values are rendered as strings in JSON-LD output

Agreed! It should not be too hard to adjust the output..

I wonder would something like this work?

Also, this is a bug as the module doesn't output correct JSON per the specifications.

elseif (is_int($value)) {

should be

elseif (is_numeric($value)) {

array_walk_recursive() only passes two arguments ($value, $key) to the callback, so I updated the callback to only expect two arguments

Going to work on this today.

I created the merge request with help from jedihe!

This will need some test coverage to make sure it works as expected and doesn't break in the future.
