I saw this question: http://forum.ganttproject.biz/view/20090416042639_1ref5t#1
It tells “read the source, Luke”, but do not answer my principle question:
is there a guarantee that the XML format won’t change ?
I am interested in using XQuery to have some reporting not available (task per user as a kanban board).
Also, a small suggestion: This could be formalized by an XSD (which would be the format documentation)
