Subject: [Wikitech-l] MultiContent Revisions and changes to the XML dumps
To: Wikipedia Xmldatadumps-l <>, Wikimedia developers <>

As many of you may know, MultiContent Revisions are coming soon (October?)
to a wiki near you. This means that we need changes to the XML dumps
schema; these changes will likely NOT be backwards compatible.

Initial discussion will take place here:

For background on MultiContent Revisions and their use on e.g. Commons or
WikiData, see: (Commons media medata) (Wikidata entites)
(MCR generally)

There may be other, better tickets/pages for background; feel free to
supplement this list if you have such links.
