Programming Language independent Model Validation

Question

Let\'s say you use several different programming languages and frameworks in your infrastructure to handle large amounts of traffic etc.

Your best bet would be a framework that allows you to specify model validation in a language agnostic format, like JSON. You might end up with a validation schema of sorts, say:

{
  "name": [
    {
      "validate": "length",
      "minLength": 6,
      "maxLength": 10
    },
    ...
  ],
  ...
}

You would then have language-specific validators that could parse this format. The validators only need to be written once, and then you maintain a single schema for each model.

However, this is probably sounding a lot like CORBA/SOAP/Thrift/ProtocolBuffers/etc. at this point. That's because they were written to solve these types of problems, and you'll end up reinventing a few wheels if you write it yourself.
