Create a course with a workshop Configure the workshop to use "Accumulative grading" as Grading strategy (in the module settings) Enrol a couple users as student (student2 and student1) and one user as teacher In the module main page, in the Setup phase of the table describing all the phases click on "Edit assessment form" Configure a couple of Aspects to use an existing scale (via the "Best possible grade / Scale to use " setting), and leave a couple of aspects more using Points As teacher, move the workshop to the submission phase As the two students, do a submission (total of 2 submissions, one per sstudent). As teacher, move the workshop to the assessment phase, allocating the assessment of the submissions: student2 will assess student1 and vice versa. Enable "Mobile services": Site administration ► Mobile app ► Mobile settings Create a Token in the mobile app service for one of the students and the teacher: Click on Site administration ► Plugins ► Web services ► Manage tokens Next, you can do a CURL REST call simulating a WS client with the student. You need to replace the wstoken with the student1 one, assessmentid with the id of the assessment assigned to this user during the allocation (the id from table workshop_assessments where the reviewerid is the student1 id) curl 'http://localhost/m/stable_master/webservice/rest/server.php?moodlewsrestformat=json' --data 'assessmentid=3&wsfunction=mod_workshop_get_assessment_form_definition&wstoken=12a2a65aeea2a177055e233f9e303218&moodlewssettingfilter=true' | python -m "json.tool" Now check that you receive in the "dimensionsinfo" field information about the aspects you created when editing the assessment form: You should see id, min, max and weight in all the aspects received and also the scale (comma separated) in those aspects using scales
