    <p>Hi,</p>
    <p>Well "the wiki is wrong" is quite a bold statement when every
      language page says exactly the same with the English version
      having done so for 6 years.</p>
    <p>Fortunately, I have a very extensive list of the current values
      (*g*) and can confirm: There are 202,203 "valid" old values in the
      database of which "only" 37,615 values use the http-notation
      (18,6%). I would dispute that that's the correct way to tag it.</p>
    <p>Also: The wiki specifically states "The reason for adding the key
      and not the full URI is that the URI might change (and already did
      in the past), but the key will stay the same. For the same reason
      the direct link to the image (e.g. <i><a class="moz-txt-link-freetext" href="https://images.mapillary.com/.../thumb-2048.jpg">https://images.mapillary.com/.../thumb-2048.jpg</a></i>)
      should not be tagged." ... We're QUITE LITERALLY seeing that the
      v3 notation of the web-app was
      <a class="moz-txt-link-freetext" href="https://www.mapillary.com/map/im/">https://www.mapillary.com/map/im/</a>... and the v4 notation is
      <a class="moz-txt-link-freetext" href="https://www.mapillary.com/app/?pKey=">https://www.mapillary.com/app/?pKey=</a>...<br>
    </p>
    <p>I'm not in favour of telling a contributor off that has 3k+
      edits, but I really don't want to leave this uncommented.</p>
    <p>Kai<br>
