Hello,
On Monday, I will begin a new year and teaching math again. So I finished this just in time .
I will update the docs, but just a few notes
This will be part of Moodle 2.3.1+ and 2.2.4+ that will be released in a few hours (I just checked the download page now and the versions are still those from yesterday so don't rush too much to download ).
Of course they will also be part of Moodle 2.3.2 and 2.2.5 to be released on september 10th, so if you are not in a hurry you can as well wait for the annoucement of these versions.
Once you have updated your moodle server with these new versions, to use the new question import format, go to Question bank and choose "BlackBoard V6+" as file format (the name is unchanged).
Then upload any .dat or .zip file (it should work with any file, be it Blackboard, testGen exported as Blackboard, Examview exported as Blackboard, including the ones that were previously imported using the "Blackboard" format) and that's all.
If you have Adriane's dragdrop matching question type installed (ddmatch) Blackboard matching questions will be imported as dragdrop questions and will not loose the html formatting in the answers. Also distractors and several subquestions with same answers now works in matching questions (even if ddmatch is not installed).
If you are importing a zip file with images, images will be imported too. The code now use Tim's idea to directly import images without encoding them so it should work even with big images or with a lot of images.
If your zip file contains several dat files with questions, all of them will be imported.
Of course now this is public, despite I did numerous tests, I am quite sure some files imports will fails, or some of you will catch questions not perfectly imported, so the best you can do is to report problems on this forum or in the tracker so that I can fix them.
I must thank all people having send me sample files since I began this work months ago, without your help nothing would have been possible, because I don't have access to Blackboard or Examview (Pearson was kind enought to provide me with a licence for the Testgen software).
I hope this work will be usefull to teachers.
