+# @swagger-api/apidom-ns-openapi-2
+
+`@swagger-api/apidom-ns-openapi-2` contains ApiDOM namespace supports following OpenAPI specification versions:
+
+- [OpenAPI 2.0 specification](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/2.0.md)
+
+## Installation
+
+You can install this package via [npm CLI](https://docs.npmjs.com/cli) by running the following command:
+
+```sh
+ $ npm install @swagger-api/apidom-ns-openapi-2
+```
+
+## OpenApi 2.0 namespace
+
+OpenApi 2.0 namespace consists of [number of elements](https://github.com/swagger-api/apidom/tree/main/packages/apidom-ns-openapi-2/src/elements) implemented on top
+of [primitive ones](https://github.com/refractproject/minim/tree/master/lib/primitives).
+
+```js
+import { createNamespace } from '@swagger-api/apidom-core';
+import openApi2Namespace from '@swagger-api/apidom-ns-openapi-2';
+
+const namespace = createNamespace(openApi2Namespace);
+
+const objectElement = new namespace.elements.Object();
+const openApiElement = new namespace.elements.Swagger();
+```
+
+When namespace instance is created in this way, it will extend the base namespace
+with the namespace provided as an argument.
+
+Elements from the namespace can also be used directly by importing them.
+
+```js
+import { SwaggerElement, InfoElement } from '@swagger-api/apidom-ns-openapi-2';
+
+const infoElement = new InfoElement();
+const swaggerElement = new SwaggerElement();
+```
+
+## Predicates
+
+This package exposes [predicates](https://github.com/swagger-api/apidom/blob/main/packages/apidom-ns-openapi-2/src/predicates.ts)
+for all higher order elements that are part of this namespace.
+
+```js
+import { isSwaggerElement, SwaggerElement } from '@swagger-api/apidom-ns-openapi-2';
+
+const swaggerElement = new SwaggerElement();
+
+isSwaggerElement(swaggerElement); // => true
+```
+
+## Traversal
+
+Traversing ApiDOM in this namespace is possible by using `visit` function from `apidom` package.
+This package comes with its own [keyMap](https://github.com/swagger-api/apidom/blob/main/packages/apidom-ns-openapi-2/src/traversal/visitor.ts#L11) and [nodeTypeGetter](https://github.com/swagger-api/apidom/blob/main/packages/apidom-ns-openapi-2/src/traversal/visitor.ts#L4).
+To learn more about these `visit` configuration options please refer to [@swagger-api/apidom-ast documentation](https://github.com/swagger-api/apidom/blob/main/packages/apidom-ast/README.md#visit).
+
+```js
+import { visit } from '@swagger-api/apidom-core';
+import { SwaggerElement, keyMap, getNodeType } from '@swagger-api/apidom-ns-openapi-2';
+
+const element = new SwaggerElement();
+
+const visitor = {
+  SwaggerElement(swaggerElement) {
+    console.dir(swaggerElement);
+  },
+};
+
+visit(element, visitor, { keyMap, nodeTypeGetter: getNodeType });
+```
+
+## Refractors
+
+Refractor is a special layer inside the namespace that can transform either JavaScript structures
+or generic ApiDOM structures into structures built from elements of this namespace.
+
+**Refracting JavaScript structures**:
+
+```js
+import { InfoElement } from '@swagger-api/apidom-ns-openapi-2';
+
+const object = {
+    title: 'my title',
+    description: 'my description',
+    version: '0.1.0',
+};
+
+InfoElement.refract(object); // => InfoElement({ title, description, version })
+```
+
+**Refracting generic ApiDOM structures**:
+
+```js
+import { ObjectElement } from '@swagger-api/apidom-core';
+import { InfoElement } from '@swagger-api/apidom-ns-openapi-2';
+
+const objectElement = new ObjectElement({
+    title: 'my title',
+    description: 'my description',
+    version: '0.1.0',
+});
+
+InfoElement.refract(objectElement); // => InfoElement({ title = 'my title', description = 'my description', version = '0.1.0' })
+```
+
+### Refractor plugins
+
+Refractors can accept plugins as a second argument of refract static method.
+
+```js
+import { ObjectElement } from '@swagger-api/apidom-core';
+import { InfoElement } from '@swagger-api/apidom-ns-openapi-2';
+
+const objectElement = new ObjectElement({
+    title: 'my title',
+    description: 'my description',
+    version: '0.1.0',
+});
+
+const plugin = ({ predicates, namespace }) => ({
+  name: 'plugin',
+  pre() {
+      console.dir('runs before traversal');
+  },
+  visitor: {
+    InfoElement(infoElement) {
+      infoElement.version = '2.0.0';
+    },
+  },
+  post() {
+      console.dir('runs after traversal');
+  },
+});
+
+InfoElement.refract(objectElement, { plugins: [plugin] }); // => InfoElement({ title = 'my title', description = 'my description', version = '2.0.0' })
+```
+
+You can define as many plugins as needed to enhance the resulting namespaced ApiDOM structure.
+If multiple plugins with the same visitor method are defined, they run in parallel (just like in Babel).
+
+#### Replace Empty Element plugin
+
+This plugin is specific to YAML 1.2 format, which allows defining key-value pairs with empty key,
+empty value, or both. If the value is not provided in YAML format, this plugin compensates for
+this missing value with the most appropriate semantic element type.
+
+```js
+import { parse } from '@swagger-api/apidom-parser-adapter-yaml-1-2';
+import { refractorPluginReplaceEmptyElement, SwaggerElement } from '@swagger-api/apidom-ns-openapi-2';
+
+const yamlDefinition = `
+openapi: 2.0
+info:
+`;
+const apiDOM = await parse(yamlDefinition);
+const swaggerElement = SwaggerElement.refract(apiDOM.result, {
+  plugins: [refractorPluginReplaceEmptyElement()],
+});
+
+// =>
+// (SwaggerElement
+//   (MemberElement
+//     (StringElement)
+//     (OpenapiElement))
+//   (MemberElement
+//     (StringElement)
+//     (InfoElement)))
+
+// => without the plugin the result would be as follows:
+// (SwaggerElement
+//   (MemberElement
+//     (StringElement)
+//     (OpenapiElement))
+//   (MemberElement
+//     (StringElement)
+//     (StringElement)))
+```
+
+## Implementation progress
+
+Only fully implemented specification objects should be checked here.
