 Under the hood this adapter uses [apidom-parser-adapter-json](https://github.com/swagger-api/apidom/tree/main/packages/apidom-parser-adapter-json)
 to parse a source string into generic ApiDOM in [base ApiDOM namespace](https://github.com/swagger-api/apidom/tree/main/packages/apidom#base-namespace)
 which is then refracted with [OpenAPI 3.0.x Refractors](https://github.com/swagger-api/apidom/tree/main/packages/apidom-ns-openapi-3-0#refractors).
