Hi mediawiki developers,<div><br></div><div>We (Google) are trying to maintain our internal mirror of <a href="http://wikidata.org" target="_blank">wikidata.org</a> up-to-date in real-time, so that our indexing pipeline can get latest interlanguage information in real-time.</div>




<div><br></div><div>I noticed <a href="http://wikidata.org" target="_blank">wikidata.org</a> is also powered by standard MediaWiki software, where standard query api to a specific revision works, e.g. </div><div>revision query: <a href="http://www.wikidata.org/w/api.php?action=query&amp;prop=revisions&amp;format=xml&amp;rvprop=content&amp;revids=6748137&amp;revids=6748137" target="_blank">http://www.wikidata.org/w/api.php?action=query&amp;prop=revisions&amp;format=xml&amp;rvprop=content&amp;revids=6748137&amp;revids=6748137</a> and</div>

<div>recentchanges: <a href="http://wikidata.org/w/api.php?action=query&amp;list=recentchanges&amp;format=xml&amp;rcnamespace=0&amp;rcprop=userid%7Ccomment%7Cflags%7Ctimestamp%7Ctitle%7Cids%7Credirect">http://wikidata.org/w/api.php?action=query&amp;list=recentchanges&amp;format=xml&amp;rcnamespace=0&amp;rcprop=userid%7Ccomment%7Cflags%7Ctimestamp%7Ctitle%7Cids%7Credirect</a></div>


<div><br></div><div>My questions are:</div><div><ul><li>Are the APIs above (&quot;action=query&amp;prop=revisions&quot; and &quot;actioon=query&amp;list=recentchanges&quot;) the supported way to retrieve <a href="http://wikidata.org" target="_blank">wikidata.org</a> in realtime?</li>

<li>Is there any document about the json format in response? It looks to me that &quot;links&quot; are about interwiki/interlanguage links (or sitelinks in <a href="http://wikidata.org" target="_blank">wikidata.org</a>&#39;s terminology), but I feel more comfortable if I see some official document about this.</li>


<li>There are some ids like &quot;<span style="font-family:monospace;font-size:13px">dewiki&quot;, &quot;enwiki&quot; etc, </span>which I guess can be interpreted to corresponding languages &quot;de&quot;, &quot;en&quot; respectively. But is there a reliable map from these *wiki to the language code? And some are even using 3-letter prefix, e.g. <span style="font-family:monospace;font-size:13px">gotwiki, </span><span style="font-family:monospace;font-size:13px">xmfwiki.</span></li>
