title: Referencing a local relative file in a JSON Schema?
body: <p>I am building a JSON for a REST web service. The schema however has grown to over 1300 lines and I want to split it up across multiple files. I am unit testing my schema against a folder of JSON sample responses using <a href="https://github.com/fge/json-schema-validator" rel="noreferrer">json-schema-validator</a> version 2.1.8. </p>
  
  <p>I know you have import types defined in your current file like <code>{ "$ref": "#/definitions/MyBool" }</code>, however if I wanted to move the definition of <code>MyBool</code> to another file, like <code>Common.schema.json</code>, how would I reference it then?</p>
  
  
  
  <p>I tried <code>{ "$ref": "Common.schema.json/definitions/MyBoolean" }</code>, <code>{ "$ref": "./Common.schema.json/defintion/MyBoolean" }</code>, and <code>{ "$ref": "file://./Common.schema.json/definitions/MyBoolean" }</code> but none of them work. </p>
  
  <p>The answer on "<a href="https://stackoverflow.com/a/9083630/254477">Does JSON Schema validation in common-js utils support references?</a>" seems like it should work but I can't seem to get the syntax right.</p>
  
  <p>I'm loading the schema with:</p>
  
  <pre class="lang-java prettyprint-override"><code>JsonNode mySchema = JsonLoader.fromReader(   new InputStreamReader(  JsonSchemaTest.class.getResourceAsStream( "/json/schema/MySchema.schema.json" )  )   );
  </code></pre>
  
  <p>and then validating it with:</p>
  
  <pre class="lang-java prettyprint-override"><code>JsonSchemaFactory.byDefault().getValidator().validate(   schema,   new InputStreamReader(  getClass().getResourceAsStream( "/json/sample/MyJsonSample.json" )  )   ).isSuccess();
  </code></pre>
  
  <p>FWIW <code>MyBool</code> looks like:</p>
  
  <pre><code>"MyBool": {
      "type": "object",
      "properties": {
          "value" :{
              "type": "string",
              "enum": [ "true", "false", "file not found" ]
          }
      },
      "required": ["value"],
      "additionalProperties": false
  }
  </code></pre>
  
  <p>When I don't try to extract <code>MyBool</code>, the schema validates all my JSON samples correctly.</p>
  
  <hr>
  
  <p>The exception I receive is:</p>
  
  <pre class="lang-none prettyprint-override"><code>com.github.fge.jsonschema.core.exceptions.ProcessingException: fatal: unable to dereference URI "file:/Common.schema.json/definitions/MyBool#"
      level: "fatal"
