I would like to discuss visualization tools for qualitative content, such as concept maps and other platforms allowing non-linear navigation, especially tools allowing to play with the visual structure of the content and helping picture how concepts and data are linked together. CMap is interesting but quite limited in the way it displays the content (linked media and other maps). I am also affiliated with a research project working on digitizing the archive of a theater company, and I would be interested in learning more about Omeka + also about Wikidot for teaching.
