Hi all,
I couldn’t find any information indicating what JSON Schema versions are supported by JSON Forms. Can you please tell me if I missed something?
Also, no schema reference ($schema) is provided in the basic example Basic Example - JSON Forms (Schema & UI Schema tabs). Is it intentional?
Hi!
We don’t support all features of JSON Schema, no matter which version. We are mostly compatible with draft-07 out of the box which is also the default supported version of AJV. To support a later JSON Schema version for validation you need to hand in a customized AJV instance.
We don’t support any of the new draft-2019-09 keywords (or later) out of the box in JSON Forms itself, however they will also no throw any errors. Not all of them are relevant for the rendering of forms, however if someone would like to contribute the additional resolving behaviors, then feel free to do it 
Hi,
Which features of draft-07 are not currently supported?
Hi @davnati,
From a validation perspective all of them are supported through AJV. However not all features of JSON Schema are easily translatable into a form, e.g. if-then-else or combinator constructs. Also we only support basic resolving at the moment, i.e. resolving from root.
Note that any missing feature which is not covered by the off-the-shelf renderer sets can be added via custom renderers.
