 Hi @diegoliv thanks for the suggestions.

 Imho this works quite well as it is now.

 > You need to turn your javascript object into a string (JSON.stringify)
 if you want to store it on the database.

 Correct, or you can use another format like CSV if it makes more sense for
 your particular case.

 > You need to handle sanitization yourself

 Correct, that's the best way to do it. You know what data to expect and
 when it would be "out of bounds".

 > If you get the metadata using get_post_meta(), it won't apply
 maybe_unserialize() before returning the metadata, you need to do it
 yourself.

 `maybe_unserialize()` is a terrible way to do things. It only exists
 because of back compat. The less it's used -- the better.

 Storing the data in a string format of your choice is the proper way here
 simply because you know what format to expect and how to sanitize it. I
 wish we could do that for all meta :)
