Used by: - OpenAPI/Swagger (1), which is the industry standard for REST API. Used by Kubernetes among others for resource descriptions - OpenRPC (json-rpc standard) - Most YAML based configuration files. GraphQL doesn't quite supersede JSONSchema because it doesn't deal with validation. (Something like Cue (https://cuelang.org/ https://cuelang.org/) might) Type systems are not typically cross-language, which is where JSONSchema tends to be used a lot. There are indeed a lot of openapi-based client generators. This one, for example, has been around for quite some time: https://github.com/OpenAPITools/openapi-generator https://github.com/OpenAPITools/openapi-generator (1) Kinda. OpenAPI schema and JSONSchema are largely intersecting sets but there are bits in both that aren't present in the other.
