title: Standard way to specify image uri / url in Marmalade manifest metadata?
body: <p>What is the &quot;standard&quot; way to provide an image URI with the Marmelade standard?</p>
  <p>There is a <code>manifest</code> but which should contain this data, but I can not see for how the URI field should be specified in the JSON string. For example should it be <code>uri</code> or <code>url</code> or <code>image-uri</code> etc?</p>
  <p>Schema from the <code>manifest</code> below</p>
  <pre><code>  (defschema mf-uri
      scheme:string
      data:string
    )
  </code></pre>
