Hi @BorisWilhelms thanks for the contribution and the tests. The code looks good to me -- one question I wanted to ask is if you found a way to create the serialized format from the object or is only de-serialization supported?

Hi @eyurtsev, currently only deserialization is supported. For serialization the $type property must be somehow present/filled. Will check the next couple of days, if there is a nice way to do that!
