Multi-Content Revisions/Dumps

This page is part of the MCR documentation

The XML dump format has changed to accommodate multiple slots per revision (XML schema version 0.11).

Some information that used to be associated with the revision is now also associated with each slot.
We tried to avoid breaking changes.
For import, MediaWiki should support the old as well as the new format.

<mediawiki>
  <page>
    <revision>
      <!-- existing id/timestamp/etc for revision data -->
      ...
      <!-- existing fields for main slot -->

      <model>wikitext</model>
      <format>text/x-wiki</format>
      <text bytes="1234" sha1="...">....</text>
      <sha1>...</sha1> <!-- revision sha1, may be different from text sha1 -->

      <!-- additional slots -->
      <content>
        <slot>filemetadata</slot>
        <model>metadata</model>
        <format>text/json</format>
        <text bytes="123" sha1="...">...</text>
      </content>
    </revision>
   </page>
</mediawiki>
