  required = NULL,
  additional_properties = FALSE,
  description = NULL
)

Arguments

...: Named schema fields, usually created with schema_*() helpers.
required: Character vector of required field names. Defaults to all supplied fields.
additional_properties: Logical. Whether properties outside ... are allowed.
description: Character. Optional schema description.

Value

A JSON Schema represented as an R list.

schema <- foundry_schema(
  sentiment = schema_enum(c("positive", "negative", "neutral")),
  score = schema_number()
)
