Bug ID: 72348
Summary: Wikidata dumps contain old-style serialization.
Product: Datasets
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: General/Unknown
Assignee: ar...@wikimedia.org

Some time ago, we changed the serialization format of wikidata items. For
consistency, we implemented on-the-fly conversion to the new format in the
exporter (using the ContentHandler::exportTransform facility).
This seems to work fine with Special:Export, and when I try it with
dumpBackup.php locally. However, the dumps like
wikidatawiki-20141009-pages-articles.xml.bz2 still contain revisions with the
old style format, both .
Is this because new revisions get stitched into old dumps? That's the only
explanation I currently have. If this is the case, how do we reset this, so all
revisions get re-exported? If this is not the case, how can we investigate what
is going wrong?
One alternative explanation would be if the host that generates the dump was
running an old version of wikibase, I suppose.
