Abstract

There is nothing so practical as a Good Theory has been the tag line for Balisage: The Markup Conference since it started in 2008. With this as the guiding principle behind a conference about markup, Balisage has been a mix of case studies, updates on specifications, tutorials, discussions of best (and sometimes worst) practice, conversations about how things should and/or do work. We have explored markup; tools used to create, manipulate and store marked-up content; markup-related information management principles; and formal and mathematical models of markup. Some of our content is solidly grounded in reality and the practices of daily production of documents, some can best be described as imaginative and fantastical. Each of these realms informs the other, often in unpredictable but rewarding ways.
