Moodle

Done. Now the whole backup/cc dir is in CVS, both in 19_STABLE and HEAD.

Missing are the integration lines to be added to Moodle core in order to make the functionality available on restore. Going to add it here as a patch.

Adding patch that enables the import of IMSCC packages from Moodle restore if experimental setting is enabled in server.

TODO:

• Decide when to enable this (simply apply the patch and done). Before or after 1.9.6. Initially I've addressed this after 1.9.6 but I cannot imagine any major problem by doing it before, so will be included in 1.9.6.

KNOW PROBLEM:

• Question answers having regexp matching won't be imported as far as Moodle short-answer qtype doesn't support regexp matching. Only exact match (varequal) and wild-card match (varsubstring) are supported by Moodle).

YAY! CONGRATS TO UVCMS AND ELOY!!!!!!!! :-D

Been trying this on 1.9.6, got three errors and it failed. Am I missing a pre-requisite?

The schema is not valid.

And which package are you trying to deploy, Martin?

It simply seems to be validation errors, so the package is invalid and won't be imported.

Ciao

Uhm... or buggy libxml... looking for the error "Could not find an augmented IDC item for an IDC definition" I've found a lot of references, like this:

http://codespeak.net/pipermail/lxml-dev/2007-May/002412.html

Ciao

Ah I should have mentioned the packages: I got them from http://www.imsglobal.org/developers/alliance/examples.cfm

OrganicChemistry.zip
Understanding_Binary.zip

Attaching one here.

Aha, the IMS-CC Alliance examples. I've tested all them and are working ok:

• OrganicChemistry: Is my favourite, with practically everything.
• Understanding_Binary.zip: Won't be imported as far as it requires authentication and we aren't supporting that.

But in any case, both are working ok here... so I guess it's a libxml problem. Ideally version 2.6.30 is the min req, obviously avoiding those buggy versions (2.7.1, 2.7.2 and 2.7.3) prone to eat html tags.

If you can confirm your versions...

Also note it's http://test.moodle.org/imscc/ ... but I'm having some problems to get it updated so it isn't operative yet due to MDLSITE-812. I've created all the shell courses and uploaded the ims-cc packages and am waiting for that bug to import all the examples there.

Ciao

Related with this:

Due to some bugs in libxml we need at least libxml >= 2.6.30 installed in the php server (right now we have 2.6.26).

I'm going to include that requisite in the code (ims-cc pre-checks). Here it's some help the UVCMS guys gave me to get updated to that version:

yum install python-devel
cd /tmp
wget ftp://xmlsoft.org/libxml2/libxml2-2.6.30-1.src.rpm
rpmbuild --rebuild libxml2-2.6.30-1.src.rpm
rpm -Uvh /usr/src/redhat/RPMS/i386/libxml2-*

(requires apache restart, of course)

Hope it helps, ciao

OK, that must be it. I have 2.6.29 on my Mac. Some version checks in the code sound essential, thanks!

Now IMS-CC import performs the check so any libxml < 2.6.30 import displays message and stops. Would be great to have test server updated asap to load all those packages and show them there.

Ciao

test.moodle.org now runs libxml2 2.6.20 and fresh php rpms have been rolled against this also

phpinfo() now reports:

libXML Version 2.6.30

Thanks Jordan!

confirmed 2.6.30 works ok, I've been able to restore all the test packages successfully in test.moodle.org/imscc

Resolving as fixed. Integration is now committed and working. So weekly builds starting tomorrow (1.9.6+) will introduce them for the masses.

Ciao

I've just downloaded an IMS CC package 'Creativity, community and ICT' from OpenLearn and imported it http://test.moodle.org/imscc Everything is perfect! Many thanks UVCMS and Eloy.

Documentation: http://docs.moodle.org/en/IMS_Common_Cartridge_import

Why was this checked in with stupid class names like quiz and forum? MDL-25048

We submitted the code and nobody complained at the time.

Just tried to upload CC packages created via Angel and these were rejected in Moodle 1.9.13 with the Critical Error that the course title was missing. This seems like perhaps too harsh an error. Is there any work continuing to be done on this importer? I ask because this is likely to become more and more significant; the courses I were trying were part of the OpenCourseLibrary's contents (cf http://cnx.org/lenses/sbctc/endorsements?b_start:int=10&-C= and follow the links to the courses for the actual CC downloads) but in addition, systems like Instructure and Blackboard are both now supporting (or saying they soon will) CC exports.
