SQL/XML Dumps

This document is for people adding features or new datasets to the SQL/XML dumps. It is focused on the implementation as deployed at the Wikimedia Foundation; if you are dumping a large number of wikis elsewhere, you will need to make appropriate adjustments.

A few documents are for adding new dump items to the non-SQL/XML dumps. These are extremely specific to the Wikimedia Foundation, but they might prove interesting to third party users.
