Digital Document Discourse Environment (D3E): exemplfies the Hypermedia Discourse approach applied in a more 'conservative' manner to traditional prose documents and threaded discussions, in contrast to the semantic discourse networks of Compendium and ClaiMaker. D3E is a toolkit for converting a static HTML document into a discussion document with rich navigational hyperlinks, tightly integrated with a discussion forum.
D3E has been used since 1996 at the OU to publish the award-winning, electronic Journal of Interactive Media in Education. JiME pioneered conversational peer review in which multi-disciplinary authors and reviewers engage in non-anonymous debate over submissions, the most interesting aspects of which are co-published with the final multimedia articles.
D3E has been released open source (but is no longer supported). A webtop 'lite' version of the Java desktop publishing toolkit is Ubiquitous-D3E, with a specialised version integrated with the University of Southampton's ePrints Archive Server, as D3Eprints.
