LibreOffice Wiki Publisher

Wikipublisher is an extension to LibreOffice 3.4.2 and above.

It lets you create Wiki articles on MediaWiki servers without having to know MediaWiki markup language. You can publish new and existing documents to a wiki page, transparently with Writer. Wiki Publisher supports essential text attributes such as headings, hyperlinks and lists, as well as simple tables. Images are also supported if already uploaded to the wiki site. Automatic images uploading is not currently supported.

This is the perfect extension if you want to make existing documentations and specifications available on MediaWiki servers. Just load the document and invoke the Extension via the "Send – MediaWiki Server" command. A dialog box guides you through the publication process. [1]
