The purpose of Utopia Documents is to help science move forward collaboratively. Because scientific knowledge is fragmented and often ‘buried’ in static content, there are many 'unknown knowns' in science. Much time is often wasted by repeating scientific experiments, by trying to verify facts, or by simply trying to find relevant further information. Utopia enables scientists to get the most from the scientific literature by providing links to appropriate web resources and metadata. Although Utopia is a PDF-reader, it bridges the web-connectivity gap with HTML content by making normally static PDFs fully web-enabled (as long as the user is online).
