That's a good description, but I'd say that we have a strongly <-> weakly typed axis and a statically <-> dynamically typed axis here. Or I might actually prefer to name the first axis poorly <-> richly typed.

            poorly typed <-------------> richly typed
    dynamic CSV, INI          JSON          YAML, Ion
    static        Bencode, ASN.1      Protobuf

What I mean by "richly typed" is that you would never read a timestamp off the wire and not know that it's a timestamp. By comparison, with CSV or INI files, you just have strings everywhere. Formats on the richly typed side have separate and explicit types for binary blobs and text, for example.
