I was actually preparing to send a note on this very topic when I read this... ODF will (I hope) be the standard way to exchange documents very soon - and of course, the more work of this kind that we do, the sooner it will be - so having an easy way to import and export ODF files will be a real advantage, especially in the currently difficult world of migrating across wikis. It would be very good if both import and export could preserve such document metadata as are common to the two document object models. That would be harder, and might require some configurable semantic mapping between the various namespaces a document might use and XWiki's. We are also involved in just such an effort, and your suggested approach is a very solid one - subject, of course, to the degree of loss that may be incurred. My tentative approach had been to keep the doc in ODF as an attachment as we currently do with the Word files, but that would not allow editing by XWiki. Drag-and-drop importation of an ODF doc via the WYSIWYG editor would be fabulous. I had intended to suggest, in accordance with my original approach, a plugin to render ODF files as HTML within an XWiki page. There is already an XSLT script (I believe) to translate ODF to HTML, but for the majority of our users (who by corporate edict are stuck in IE jail) it has to be translated on the server. brain[sic]
