OOo Extension – Sun Wiki Publisher

The Sun Wiki Publisher enables you to create Wiki articles on
MediaWiki servers without having to know the syntax of the MediaWiki
markup language. Publish your new and existing documents transparently
with the Writer to a wiki page.

All important text attributes such as headings, hyperlinks, lists
and simple tables are supported. Even images are supported as long as
they have already been uploaded to the wiki site. An automatic upload
of images is currently not supported.

It is the perfect extension for all users who want to make existing
documentations and specifications available on MediaWiki servers. Just
load the document and call the Extension with ‘Send – MediaWiki
Server’. A dialog will guide you to publish your document.
