Forum .LRN Q&A: Problems integratin IMS-LD and IMS-QTI

Hi,

I'm using dotLRN 2.3.1 and trying to integrate the use of IMS-LD and IMS-QTI.

I designed a course using IMS-LD and now I want to add a Test defined with IMS-QTI.

I could upload the test to the platform without any problem and I could open it.

The problem comes when I add the test as a resource to the course and it doesn't open as a test in dotLRN.

I defined it as a resource with type imsqti, like this:
<resource type="imsqti_xmlv2p0" identifier="resource-impressionism-eval" href="resources/imsqti-impeval.zip">
    <file href="resources/imsqti-impeval.zip"/>
</resource>

When I try to open the test, it doesn't open and I only can download a zip file with the imsqti.

Do you know what is happening??

Thanks, javier

Hi Jose,

I tried to do what you said, and it's not working.

I defined the resource like imsqti_xmlv1p1 or imsqti_item_xmlv2p0, but it seems that it is another thing.

I define the imsmanifest.xml file from the test with this part:

...
        <resources>
                <resource identifier="RESOURCE1" type="imsqti_xmlv1p1" href="imsqti-impeval.xml">
                        <file href="imsqti-impeval.xml" />
                </resource>
        </resources>
...

Then in the imsmanifest from the course I define this test, as a new activity with one resource, like:

...                                        <imsld:learning-activity identifier="LA-task4.1" isvisible="true">
                                              <imsld:title>4.1. Impressionism Evaluation</imsld:title>
                                                <imsld:environment-ref ref="ENV-webquestart"/>
                                                <imsld:activity-description>
                                                        <imsld:item identifierref="resource-impressionism-eval" isvisible="true">
                                                                <imsld:title>Impressionism Eval</imsld:title>
                                                        </imsld:item>
                                                </imsld:activity-description>
                                                <imsld:complete-activity>
                                                        <imsld:user-choice />
                                                </imsld:complete-activity>
                                        </imsld:learning-activity>

...
                <resource type="imsqti_xmlv1p1" identifier="resource-impressionism-eval" href="resources/imsqti-impeval.zip">
                        <file href="resources/imsqti-impeval.zip"/>
                </resource>
...

Do I have to do anything else?? Where is the problem??

Thanks, javier

Hi Luis,

I found in the file

/dotlrn/packages/assessment/tcl/as-callback-procs.tcl

the next:

...
ad_proc -public -callback imsld::import -impl qti {} {
    this is the imsld qti importer
} {
        if {$res_type == "imsqti_xmlv1p0" || $res_type == "imsqti_xmlv1p1" || $res_type =="imsqti_item_xmlv2p0"} {
            return [as::qti::register_xml_object_id \
                        -xml_file $tmp_dir/$res_href \
                        -community_id $community_id]
        }
}
...

It seems the same...

Now I know, that I have the same code, which is the way to check if it's being executed??

I'm new in this "world" of OpenACS and dotLRN and I really don't know if it's something of the platform or just, that I'm making any mistake in my code.

I'm trying to find a course that could upload without problems, but I didn't have lucky yet...

Regards, javier

Javier, Would it be feasible to get a hold of the Learning Unit you are trying to parse? Or may be a simplified version of it that still manifests the same anomaly?

We tested the QTI integration, but this seems something we overlooked.

Let us know.

Regards.
