I imported both Bb5 and Bb6 files using the latest CVS and the only problem I ran into was a general mod/resource/restorelib.php bug. (There's a missing left paren on line 85 in cvs.)
Both courses imported fine for me, though Bb6 still only imports basic text items.
What happens when you try to import a Bb 6.1 file?
So no quiz items supported? The BB import in quiz is also not working for us, I guess that would be the best place to focus.
What happens when you try to import a Bb 6.1 file?
Different errors. Right now I'm getting :
You need the XSLT library installed in PHP to open this Blackboard file
Using php 5.0.2 with:
xml
| XML Support | active |
| XML Namespace Support | active |
| libxml2 Version | 2.6.11 |
xsl
| XSL | enabled |
| libxslt Version | 1.1.7 |
| libxslt compiled against libxml Version | 2.6.11 |
| EXSLT | enabled |
| libexslt Version |
such missing parenthesis was my fault, sorry.
Ciao
I have been working on testing the importation of Blackboard courses and tests on Moodle 1.5. I have been able to import BB5.5 question pools through the import oprion in the quiz module, but have had no luck with BB6.
I believe this is because between version 5 and 6, Blackboard has changed the format in which it exports quizzes/tests. While both 5.5 and 6 exported question pools take the form of XML files, they do not have much in common. For example, the first tag in a 5.5 question pool file is <POOL>, while the first tag in a version 6 exported question pool is <questestinterop>, and it doesn't get much more similar from there. This leads me to believe that Blackboard is now using the IMS QTI format for question pools. At this time, the IMS QTI import option in Moodle is placeholder for a feature hopefully added in the future.
So, unless I am mistaken, the "Blackboard" test import option in the quiz module is more accurately a "Blackboard 5" function.

for the status of IMS QTI support in Moodle.
Also you might check out http://www.respondus.com to see if they might support BB6->BB5.5 export. There is a fully functional 30-day trial version of their software that you can download.
We should have something ready for testing next week or so.
Man that is some ugly XML, but generally it looks like it's going to work ok, Jeff is trying to get the MathML to come over now (using the filter in contrib), and then images. We're coding this against 1.4.4, so hopefully there will be backwards compatability in the import structure in 1.5?
Yesterday it was mostly working, 2 problems at this point:
- BB Essay questions: we plan to map them to the essay question type Mark Nielson coded up, or is there going to be a new one in 1.5 (haven't seen it in dev)?.
- BB matching which allows 2 choices, while Moodle needs 3--we'll have to throw an error for these unless someone can code up a "Blackboard matching question"?
That filter depends on the Xalan XSLT processor, which is Linux only, and even there a challenge to install, as it has many nonstandard dependencies. Unless you've found a simpler alternative to Xalan?
You might want to get in touch with Davide Cervone of Union College. He coded a Javascript filter for rendering Latex in Javascript, which is also in contrib. While that script won't work with MathML, he has variants that do work.
That's great! I have been trying to get question pools across by re-formating them in Respondus, but haven't had much success. The ability to import 6.1 question pools would be a great thing to take to faculty who are concerned about having to recreate all or large parts of their courses for a potential LMS migration.
Thanks for the good news, Michael!
Very interesting post. Would you be able to share the script that you wrote to find out how many courses used Bb's quizzes? I think many people would be curious about the data that it produces.
I am Trying Jeff's BB-6 import and am getting :
Fatal error: Cannot instantiate non-existent class: quiz_format_blackboard_6_pool_import in c:\program files\nusphere\techplat\apache\htdocs\moodle\mod\quiz\locallib.php on line 2030
any Ideas ?
Basically, you will need to change the class definition in blackboard_6_pool_import/format.php to what it says in the error - quiz_format_blackboard_6_pool_import (the last bit has to match the directory name).
You will also need to add a new method to the class...
function provide_import() {
return true;
}
BUT... there have been other changes in quizzes that break old import/export routines in more subtle ways. If someone gives me the code (quickly - on holiday next week), and some comprehensive sample data I will have a look.
That last directory name (format_6) really matters!
Seems to work in BB 6.0
in a Spanish Quiz there are problems in the character ie paÃses ,opinión ,pública
| 19 ( 39) Marks: --/1 | El terrorismo y las prácticas terroristas tienen el objetivo de:
|
That last posting did not work very well
What I wanted to say is the BB6.0 worked well ,However the Spanish quiz had problems with the words as an example
Question
I'm English remember, we are lucky we speak our own language, never mind anybody elses
Having problems entering the messages in this forum - hence my cryptic message
What I wanted to say and point out is that BB60 import works fine for me but, that certain characters in Spanish and perhaps other language sets are not being translated properly -example:
El terrorismo y las prácticas terroristas tienen el objetivo de:
Answer:
a. Mantener los paÃses enemigo bajo control
b. Manipular la opinión pública
c. Lograr el poder que de otra manera no se lograrÃa.
"the editor that created the file" what editor are you referring to?
The quiz was imported from blackboard where it mapped the characters properly.
I would have expected that the import program would have mapped the characters properly from BB.
They did not map properly and thus the problem of character errors in the Moodle quiz.
Or am I making an assumption that does not make sense?
I stress that I am guessing what has happened here, having seen neither the exported file or the code, but if I was a betting man.....
It might work to open the BB zip, extract the XML file, convert the characters, then re-insert the XML file into the zip before importing.
Tried your suggestion ...now nothings works
i.e. no reponce from the import -- blank screen
The importer will also check for the essay question type, but if you don't have either it should throw a (non-fatal) error letting you know those types can't be imported.
PS it's enourmously different from BB 5.5 (I believe that is what the code in Moodle standard imports?), the exported 6.1 XML has some nested ifs that approach the limits of comprehension.
There is a folder inside "blackboard_6_pool_import" called "blackboard_6" that is what should be dropped in mod/quiz/format
I tried to import a quiz from Blackboard 6 file and here is the error I got.

I am using Moodle 1.6 which I got from the CVS and I have added the blackboard_6 import directory and RENDEREDMATCH patches to my version of Moodle.
Any clues why this is happening?
I think you ran into version mismatch problem. I guess blackboard_6 import doesn't work w/ 1.6. I'm using 1.5.2 w/ blackboard_6 import and it works fine.
