Thanks, @SebastianBoblestETAS. I agree that json is a great format for serializing, but I have a few questions:

1. What are the pros and cons of json format compared with TVMScript (if we have python env)

2. How to design a json format to store all TIR information for all possible nodes? Do you have examples to show it?
