What this is

This package contains the core mechanics of json-schema-validator library. It also provides a comprehensive infrastructure to build processing chains for anything you can think of, really. To this effect, this package can be used, for instance, to perform the following, provided you use the appropriate software packages:

• generate a JSON Schema from a POJO, and then validate instances against that schema;
• transform different, related schema formats into JSON Schema, or the reverse (for instance Avro);
• conditional patching/deserialization;
• etc etc.

You can see sample usages of this library in a separate project which is demonstrated online. More details on this library can be found here.

This library supports Draft 03 and Draft 04. Contribution of support for Draft 05 (issue #61), Draft 06 (issue #62), or Draft 07 (issue #63) would be gratefully accepted.

Versioning scheme policy

The versioning scheme is defined by the middle digit of the version number:

• if this number is even, then this is the stable version; no new features will be added to such versions, and the user API will not change (save for some additions if requested).
• if this number is odd, then this is the development version; new features will be added to those versions only, and the user API may change.
