Hi,
There is a brand new Drupal group related to DITA XML-based documentation:
DITA Tech Comm CMS
https://groups.drupal.org/dita-tech-comm-cms
I'm posting this announcement here because the group is still pending moderation and therefore doesn't show yet in the list of new groups. Please join if you are interested in combining DITA and Drupal.
Kind regards,
Frank
