title: MQL for Persons with Wikipedia Articles
body: <p>I am trying to return a list of people in wikipedia that have dates of birth listed. The code below works for English Wikipedia, but will not return persons in non-English wikis. How can I return a list of people who are in any wikipedia?</p>
  
  <pre class="lang-json prettyprint-override"><code>[{
    "id": null,
    "name": null,
    "type": "/people/person",
    "date_of_birth": [{
      "optional": "required",
      "value": null
    }],
    "/wikipedia/topic/en_id": [{
      "optional": "required",
      "value": null
    }]    }]
  </code></pre>
