title: How do I eliminate keys from MediaWiki External Data JSON?
body: <p>I am using MediaWiki 1.27 with the External Data extension. The external data is only available in JSON format. Unfortunately, the data returns duplicate key names, where some are nested. See example:</p>
  
  <pre><code>[
      {
          "created": 1481938823000,
          "name": "3D Thursdays &amp; Open House",
          "venue": {
              "name": "HacDC",
              ...
          },
          "group": {
              "name": "HacDC",
              ...
          },
          ...
      },
      ...
  ]
  </code></pre>
  
  <p>When attempting to display the data with:</p>
  
  <pre><code>{{#get_web_data:
  url=https://api.meetup.com/hac-dc/events?scroll=next_upcoming&amp;page=10
  |format=JSON
  |data=local_date=local_date,local_time=local_time,name=name,link=link,duration=duration
  |cache seconds=0
  }} 
  
  {| class="wikitable"
  ! Date
  ! Time
  ! Event {{#for_external_table:&lt;nowiki/&gt;
  {{!}}-
  {{!}} {{{local_date}}}
  {{!}} {{{local_time}}}
  {{!}} [{{{link}}} {{{name}}}]
  }}
  |}
  </code></pre>
  
  <p>MediaWiki appears to have no obvious way to ignore the nested <code>name</code> keys, and displays an entry for "3D Thursday &amp; Open House" (correct) and "HacDC" and "HacDC" (both incorrect).</p>
  
  <p>Is there a way to explicitly exclude the <code>venue</code> and <code>group</code> "dictionaries" or display only "outer" values?</p>
