RK> I'll probably have time to implement these modules some time soon, though. OK, the outlines of this project are clear: The format to be produced is http://www.mediawiki.org/xml/export-0.3/ and up. The query string would be api.php?action=query&format=export ... That will finally give Special:Export an API. Probably no import API is needed as that could all be achieved with a HTTP GET with the existing Special:Import. The same could be said about Special:Export, but the latter lacks batch job generator capabilities.
