Thank you for this excellent plug it. At IIT Delhi, we are trying to write custom evaluation scripts for grading that examine previous submissions and compare with their next submissions and give penalty based on the difference in the two submissions.
We can bulk download all the submissions of all the students using download all submissions link. However, we are facing problems linking the submissions to the Moodle's ID number. The directory names for different students are in the format: <last name> <first name> <moodle code>. However, this code doesn't come in the grader report. How can we link this code to the actual student <ID Number> in the grader report (or email address)? The first names and last names can be ambiguous in large classes where multiple students may have the same first and last names.
