body: <p>How to define <code>map[string]</code> object in YAML?</p>
  
  <p>I have JSON object</p>
  
  <pre><code>{
      "name": "SampleStore",
      "books": {
          "sample1": {
          "author": "test1",
          "prize": "1221"
         },
          "sample2": {
          "author": "test2",
          "prize": "890"
         }
      }
  }
  </code></pre>
  
  <p>I had defined object in YAML as:</p>
  
  <pre><code>Types:
      store:
          name:
              type: String
          books:
              Items:
                  Referemce: book_details
      book_details:
          author:
              type: String
          prize:
             type: String
  </code></pre>
  
  <p>But this is syntax for list, I want map of book. How to define these type of map in YAML?</p>
