| description: > | |
| An include file to define the [{json:api} 1.0 specification](http://jsonapi.org/format). | |
| N.B. I've got some confusion going on between a validating a jsonapi schema and defining one! | |
| This file also provides a limited demonstration of jsonapi with path items for collections, items | |
| and their methods. You should be able to open in a modern version of | |
| [swagger-editor](https://github.com/swagger-api/swagger-editor) or | |
| [swagger-ui-watcher](https://github.com/moon0326/swagger-ui-watcher). | |
| This file was created by downloading the [schema definition](http://jsonapi.org/schema) | |
| and then editing as needed to make it useful with the Open API Specification. It is subject | |
| to the `CC0 1.0 Universal` license as it is derived from the {json:api} specification. | |
| Several changes had to be made to that schema since it is non-normative and primarily only documented | |
| the results of GET operations. See especially definitions of `post_datum`, `post_resource`, `datum`, | |
| and `metaonly` that were added. | |
| **USAGE** | |
| You can reference definitions in this schema with `$ref` as defined in the OAS specification, but | |
| be aware that the | |
| "[[Reference Object](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.2.md#reference-object)] | |
| cannot be extended with additional properties and any properties added SHALL be ignored." So $refs are pretty | |
| useless if you are trying to keep things DRY. | |
| Specifically, you'll need to copy and the path items into your own schema doc and "extend" them by adding | |
| what you need (e.g. security, additional parameters, referneces to your app's request/response schemas, etc.). | |
| For example: | |
| ``` | |
| paths: | |
| /courses/: | |
| get: | |
| description: Returns a collection of courses | |
| operationId: find courses | |
| security: | |
| - basicAuth: [] | |
| - oauth: [auth-columbia, read] | |
| parameters: | |
| # I wish I could pull all these in at once... | |
| - $ref: './jsonapi.yaml#/components/parameters/include' | |
| - $ref: './jsonapi.yaml#/components/parameters/sort' | |
| - $ref: './jsonapi.yaml#/components/parameters/pageSize' | |
| - $ref: './jsonapi.yaml#/components/parameters/pageNumber' | |
| - name: 'filter[id]' | |
| in: query | |

| required: false | |
| style: form | |
| schema: | |
| $ref: './jsonapi.yaml#/components/schemas/id' | |
| responses: | |

| description: not authorized | |
| content: | |
| application/vnd.api+json: | |
| schema: | |
| $ref: './jsonapi.yaml#/components/schemas/error' | |
| ``` | |
| You can locate this file on a web server or in a local directory and `$ref` it appropriately; `swagger-ui-watcher` | |
| will follow the `$ref`s and can be used to "bundle" your schema into a single JSON document as follows: | |
| ``` | |
| swagger-ui-watcher -b myapp.json --path myapp.yaml | |
| ``` | |
