What is the proper way of using gradingform_rubric_grader_gradingpanel_fetch? I couldn't find a detailed explanation about it. For example; its parameters are component, contextid, itemname, gradeduserid but I'm not quite clear about the possible values of component, contextid and itemname.
I have 2 use cases:
1) I need to get the criterion and its rubric levels of an assignment using web services
2) I need to get the rubric assessments of an assignment using web services. In other words, rubric grades of student submissions.
Is there any resource that I can follow? Or any explanation here would be greatly appreciated.
