Intro

An implementation of JSON Schema Draft 4 in haskell.

Status

Still in development. Lacks documentation and solid code to fetch remote schemas.

Install Tests

git submodule update --init

Run Tests

cd JSON-Schema-Test-Suite/remotes
python -m SimpleHTTPServer 1234

Then run the normal cabal test from another terminal.

Note that the tests require an internet connection.

Notes

• This uses the regexpr regular expression library fo the "pattern" validator. I have no idea if this is compatible with the ECMA 262 regex dialect, which the spec requires.

• draft4.json is from commit # cc8ec81ce0abe2385ebd6c2a6f2d6deb646f874a here.

Credits

Thanks to Julian Berman for the fantastic test suite.

Also thanks to Tim Baumann for his aeson-schema library. Hjsonschema's test code and its implementation of Graph both come from Aeson-Schema.
