Provide a JSON Schema

[hco]

It would be great if you could provide an official JSON Schema for the engine json file.

would be good to have a spec defined for all Data Types indeed.

that way, after one generates the report, he can actually validate if his report is respecting the spec or not. ref https://github.com/FriendsOfPHP/PHP-CS-Fixer/pull/4563

any update on this would be highly appreciated.

Creating a JSON format without a schema is a big issue these days.
