In this video I demonstrate the results of the work of my colleagues Denes and Tamas, who built a first implementation of a Drupal site that takes DITA topics and let's you add them in a mindmap interface to a DITAmap and than export them using the DITA Open Toolkit.
This is a follow up on the blog posts I published a month ago: one with an interface mockup and the other post with a mindmap to ditamap conversion proposal.
