WikiAccess is a library, that provides access to MediaWiki-based wiki sites
I commited some changes and improvements to the code since its last release, but I am unable to upload a new release. So if you want the latest updates (login with windows credentials, file download and upload, ability to export, delete pages, ..) get the sourcecode from svn and compile it for yourself :)
A good set of APIs. It saved me a lot of time. Found it when I was about to write my own set of APIs to intergate mediaWiki and Sharepoint. Very easy to understand and modify it to meet your requirements. Well done!. Good work.
