Allow a user to export all of their content

[chrismgraham]

It should be possible for a user to export all of their content, to have the peace of mind of a personal backup.

[chrismgraham]

Either as a single button in their profile or on a project by project basis in their list of projects?

[christianp]

I think both: export all of my content, and if I have access to a project, export all of its content.

This would, I think, be a very useful addition (and might not even be that hard to do, since questions and exams already have a "download source" method?) - for me the main point would be to "sleep better" if I had a backup of all of my content, so that I could in an emergency case migrate everything to a Numbas editor instance which I run myself. (Say when the public Numbas editor has some hardware or network problem ... which is surely unlikely, but since it's not at all something the user can control, a backup would be good.)

For this use case, being able to download a zip file with the source files of all questions and exams would be good enough. This would already be helpful without a restore function, I think, because in that unlikely emergency case it would be feasible to upload the source files manually.

Currently, if I understand correctly, I have to download questions/exams individually, which is possible, but a bit painful (and it's easier to forget some part).

[bremner]

As a workaround is it enough to save a fake exam with all questions in it, or do I need to save the questions individually?

[christianp]

@bremner When you download the source of an exam, it contains all the information necessary to recreate the questions, except for any attached images. That's a limitation of the source download for both questions and exams at the moment - I need to sort that out.

@christianp , are there any more plans regarding exporting content?

And, I was hoping for QTI support to allow easy migration to/from Numbas?

[christianp]

@Spruce8913 sorry, I haven't made any progress on this yet.

QTI export won't be possible: the QTI standard is very limited, so almost none of what you can do in Numbas could be represented in QTI format. I can go on at length about the limitations of QTI, and the time people have wasted trying to make maths assessment systems interoperate.

Thank you for the clear response!
