package genschema

import "github.com/goadesign/goa/goagen/gen_schema"

Package genschema provides a generator for the JSON schema controller. The schema controller responds to GET /schema requests with the API JSON Hyper-schema. This JSON schema can be used to generate API documentation, ruby and Go API clients. See the blog post (https://blog.heroku.com/archives/2014/1/8/json_schema_for_heroku_platform_api) describing how Heroku leverages the JSON Hyper-schema standard (http://json-schema.org/latest/json-schema-hypermedia.html) for more information.
