Forwarding as this will also be relevant for people who consume Wikidata XML dumps (but not entity dumps), and especially for people who are interested in working with Structured Data on Commons from dumps.

Subject: [Wikitech-l] BREAKING CHANGE: schema update, xml dumps
To: Wikipedia Xmldatadumps-l <Xmldatadumps-l@lists.wikimedia.org>, Wikimedia developers <wikitech-l@lists.wikimedia.org>

We plan to move to the new schema for xml dumps for the February 1, 2020
run. Update your scripts and apps accordingly!

The new schema contains an entry for each 'slot' of content. This means
that, for example, the commonswiki dump will contain MediaInfo information
as well as the usual wikitext. See
https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/core/+/master/docs/export-0.11.xsd
for the schema and
https://www.mediawiki.org/wiki/Requests_for_comment/Schema_update_for_multiple_content_objects_per_revision_(MCR)_in_XML_dumps
for further explanation and example outputs.

Phabricator task for the update: https://phabricator.wikimedia.org/T238972

PLEASE FORWARD to other lists as you deem appropriate. Thanks!

Ariel Glenn
