XML dump
Consumerium must be able to do an XML dump of the Content Wiki and Opinion Wiki at any time, if the material in them is GFDL:
The terms of the GFDL require certain access to source text. Any element of the GFDL text corpus must remain available in source form to anyone, and no page in it can be distributed without the URL of a source form that can be instantly retrieved by anyone. This includes those "banned" by the sysop power structure. Mediawiki provides this with the Special:Export facility in recent versions, and for unblocked IP's with "edit page" or "view source" links on every page do MoinMoin or tikiwiki? on Usemod no one seems to ever block IPs either.
We have XML-export enabled for this Development Wiki since the upgrade to the new MediaWiki-software, but the only wiki-software that currently supports the import is GetWiki.
The GFDL guarantee also includes those who do not intend to use the mediawiki software. Bulk dumps are available only in MySQL dump format, which can be difficult software to run, and, is certainly not suitable for most purposes of a large public wiki (text searches, for instance, take an extraordinary amount of compute and disk time).
