README

json-schema

json-schema is like XML schemas, but for JSON. It's haskell specific and has no relation to json-schema.org.

The package provides

An AST type Schema defining the structure of a JSON object.
A type class JSONSchema to define a schema for a type.
Combinators for defining schemas.
A module for validating Aeson values against schemas.
Built-in instances matching aeson's.
A Generics module matching aeson instances generated by generics-aeson

If you use another library for generating JSON instances (such as aeson's built-in generics/template haskell) or write aeson instances by hand you will not get matching JSONSchema instances if you use json-schema's generics module.

This package assumes that your ToJSON and FromJSON instances match.
