CDDL

Write a specification in CDDL for what the overall structure of your CBOR data should be. Generate example instances from that specification. Validate instances against the specification. Specifications are as simple as:

reputation-object = {
  application: tstr
  reputons: [* reputon]
}

reputon = {
  rater: tstr
  assertion: tstr
  rated: tstr
  rating: float16
  ? confidence: float16
  ? normal-rating: float16
  ? sample-size: uint
  ? generated: uint
  ? expires: uint
  * tstr: any
}

(Example based on RFC 7071.)

Installation: gem install cddl

(CDDL Specification: RFC 8610.)
