Designing Quality JSON Schema Errors

Intro

The JSON Schema spec doesn't speak on error construction at all (which is absolutely the right decision).

This means that each library author has to figure out how to construct informative errors individually.

This document is meant to sketch out some best practices.

Example

A list of every data exchange formats I could find

At work, I just spent the last few weeks exploring and evaluating every format I could find, and my number one criteria was whether they supported sum types. I was especially interested in schema languages in which I could describe my types and then some standard specifies how to encode them using an on-the-wire format, usually JSON.

  1. Swagger represents sum types like Scala does, using subtyping. So you have a parent type EitherIntString with two subtypes Left and Right represented as {"discriminator": "Left", value: 42} and {"discriminator": "Right", value": "foo"}. Unfortunately, unlike in Scala in which the parent type is abstract and cannot be instantiated, in Swagger it looks like the parent type is concrete, so when you specify that your input is an EitherIntString, you might receive {"discriminator": "EitherIntString"} instead of one of its two subtypes.
  2. JSON-schema supports unions, which isn't quite the same thing as sum types because
