Differences between JSON from Frictionless data and other schemas

[cuducos]

I have seen choices in JSON Schemas while pairing with @mariorodeghiero , but

1. I couldn't find its specification and
2. as far as I understood from this issue it was discarded in favor of a particular use case of oneOf.

Also, I have also seen resource_fields and I couldn't find the specs for that.

Maybe the JSON we (Mario and I) were discussing is not a strict JSON Schema. If that is the case, should we support fields like that (choice and resource_fields on these examples)?

How will that relate to JSON Schema specs implemented and planned so far?

INVALID. The schema you were looking at was not a JSON Schema.
