From what I have seen, the excessive topological frameworks on top of JSON have never really take off. There have been many schema systems available for 10 years now but for some reason everyone seems to fall back to accepting basic JSON. There is a place for this stuff but only in very limited areas. Hopefully it does not go too far, for example like Microsoft did with SOAP. I still have nightmares from work decoding completely wrong XML generated by the native SOAP XML generators in old C# banking apps.
