The zip file created in educommons platform can´t be imported in moodle. The zip file contains imsmanifest.xml and three *.xsd but no moodle.xml after Administration/Recovery of the file is generated so the recovery is canceled.
I have used the atlassian tool sugested by Hellen Foster and got a new imsmanifest.xml file for importing in moodle. But, sadly, when I try to recover the IMS package with that new xml in my moodle site I got a new error: "course_header object missing from session". This time the moodle.xml file and the course files folder are created in /moodledata/temp/backup but the course is not recovered.
I have read this as a reported error concerning Blackboard in http://moodle.org/mod/forum/discuss.php?d=92477 and other posts but no solution offered that I can find.
