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.

any update on this would be highly appreciated.

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