So here's how I think this fits into all the other different types of data serialization:

Schema-ful, copying: Protobuf, Thrift, plenty more

Schema-ful, zero-copy: Cap'n'proto, Flatbuffers

Schema-less, copying: Json (binary and other variants included), XML

Schema-less, zero-copy: Flexbuffers (Any others? This seems new to me)
