[pydry]

I think there's an argument to be made that validation should be done with a turing complete language to be most effective. However, JSON schema, while weaker and more verbose does have the advantage of programming language independence which whatever typescript has absolutely does not.

Either way JSON schema is fairly lightweight and didn't try to accidentally create an awful new programming language (cough XSLT cough). I don't see it as indicative of any of the kind of fuck ups XML went through.
