Workshop module stores personal data in its tables, via user
preference and via core_files and core_plagiarism subsystems.
When exporting the data, we export not only data created by users
themselves (such as their submissions and provided peer-assessments) but
also all relevant data that can (or must) be used to interpret created
content and evaluate the user's performance and skills.
On the other hand, when deleting data at user's request, we delete only
those data that do not affect other users' performance evaluation. The
reasoning is that one's right for privacy does not overweight someone
else's right for fair assessment. For that reason, we can't fully delete
whole provided peer-assessments, for example. Because they are used in
cross-comparison and grading evaluation of all other peers who assessed
the same submission. So instead, we replace provided texts but still
keep the original record.
Workshop defines the interface for its grading strategy subplugins to
allow them attach personal data under their control to the exported
structures.
It was reported at the Open University that there have been some
problems with the formats of files submitted by students. Not all
students completed their outlines as a Word .doc (despite this being the
format of the template provided). Some formats (e.g. .pages) couldn’t be
translated by some of the reviewing students. Therefore, they were
unable to provide a review and the submitting students not receiving any
comments.
This patch allows the teacher to define list of allowed file types that
can be attached to submitted work and/or overall feedback in the
workshop.
This is a basic implementation of the actual content generation in the workshop
generator. Note the we do not generate actual grading form data (which is what
the grading strategy plugins would do), just their results.
