While working on creating API specifications using RAML, many times, we need to create a RAML Library or DataType from JSON payloads. We can accomplish this manually by using an API modeling tool like MuleSoft Anypoint Design Center.

It is better to use a tool that helps automate the conversion. ramldt2jsonschema is one such tool. It is a CLI and library for converting a RAML 1.0 DataType to a JSON schema, and back.
