How to specify @lang in setSetJson() object?

[lazharichir]

Hello! I cannot find this in the README.md but how do we go about passing the language for a predicate in the json object we want to mutate?

{
<0f27fd12> <label@en> "Dog" .
<0f27fd12> <label@fr> "Chien" .
}

How do basically do this with the Mutation.setSetJson(obj)'s object?

p.s. and also how to delete label@en using the setDeleteJson()?

The JSON below should work for setting and deleting.

{
  "uid" : "0f27fd12",
  "label@en": "Dog",
  "label@fr": "Chien"
}
