title: Read Alfresco custom metadata via OpenCMIS?
body: <p>I created a new Alfresco document, and added a custom aspect (EXIF aspect) to it.</p>
  
  <p>How to get the values of this metadata via OpenCMIS/DotCMIS?</p>
  
  <p>I tried the following but it does not show the EXIF metadata (nor presumably any custom aspect metadata):</p>
  
  <pre><code>foreach(IProperty property in document.Properties)
  {
      if (property.IsMultiValued)
      {
           metadata.Add(property.Id, property.ValuesAsString);
      }
      else
      {
           metadata.Add(property.Id, property.ValueAsString);
      }
  }
  </code></pre>
