Support for copying content associated with an LTI tool?

[christopher_phi]

When an LTI tool associated with a course is copied to another course the LTI tool itself is copied to the new course, but my understanding from the past at least was that there was no way to communicate to the LTI tool that would relate the origin course with the new course. 

For example, if I have a Media LTI tool with videos associated with a specific course and then copy the course it will copy the Media LTI tool but there has not been a way to tell the Media LTI tool that the videos associated with the first origin course should also be associated with the new course the content was copied from. 

However, with New Quizzes operating as an LTI tool my understanding is that when you copy a course forward it also copies the associated quiz banks. I am trying to understand how this happens and if there is anything in the LTI specification or a way that an LTI tool can be built so that when it is copied from into a new course, it can know the course ID of the course it was copied from. Thanks!

When an LTI tool is launched you can ask for a variable to be passed in that will tell you the previous courses and/or contexts that instance of the tool will have had and then the LTI tool can at that point can optional copy any previous content.

The complete list of variables is on https://canvas.instructure.com/doc/api/file.tools_variable_substitutions.html

The ones you're interested in are:

Canvas.course.previousContextIds‍
Canvas.course.previousContextIds.recursive
Canvas.course.previousCourseIds‍‍‍

and these can be put in a LTI XML registration file like this:

<?xml version="1.0" encoding="UTF-8"?>
<cartridge_basiclti_link xmlns="http://www.imsglobal.org/xsd/imslticc_v1p0"

Thank you so much  @matthew_buckett ‌, this is exactly what I was looking for - much appreciated!

I have a bit of a follow up on this, I shared that information with the LTI provider we are working with hoping it would be possible and received this feedback: 

"The solution they offer is not applicable. using the {{previousContextIds}}is not something that canvas can promise that the value in would necessarily be a *singular (*previous course ID) nor the order of it."

I did some more digging and found a similar question Can tools be informed about course coping that answers a similar question that there isn't currently a way to do exactly what we are hoping - or at least not a documented way.  I just tested with "New Quizzes" and it does appear that it is operating as an LTI tool with a way to automatically copy over content so I think there must be a way - I just need to figure out how. Any ideas are welcome. 

Thank you to  @matthew_buckett ‌ for the other thread and for your answer which will be helpful to others who have similar questions
