IVLE users can be given roles, giving them additional power in the system. The
25
roles are centered around a typical university teaching structure, with
26
tutors, lecturers and system administrators.
28
This page lists precisely what is permitted by each role.
30
Note that the roles are hierarchical. Being a member of a role implies all of
31
the powers of lesser roles.
33
Most roles are *per-offering*, which means the user only has the powers of
34
that role when dealing with a specific offering of a subject. (For example, a
35
lecturer of subject "ivle-101" for 2009 semester 1 is just an ordinary user
36
with respect to any other subject, or any other offering of "ivle-101").
41
This is the default role for any user. Note that we do not refer to "ordinary
42
users" as "students", because "student" implies an enrolment in a particular
45
All users have the ability to:
47
* Store and edit files in the file system,
48
* Execute Python code in the Python console,
49
* Serve files privately and publicly,
50
* View and edit some of their own details (e.g., can edit display name, but
51
not full name, which is required to be the user's formal name).
56
The role of "student" is offering-specific. Any user enrolled in an offering
57
is a "student" in that offering.
59
In addition to the abilities of ordinary users, students have the ability to:
61
* View the "subject page" for the offering,
62
* View any worksheet in the offering, and its exercises,
63
* Submit attempts at any exercise in any worksheet in the offering,
64
* Receive a mark for worksheet completion in the offering,
65
* Submit a solo project for the offering,
66
* Submit a group project for the offering, on behalf of any group they are in.
71
The role of "tutor" is offering-specific. Users may be enrolled in an offering
72
as "tutor" by a lecturer or admin.

In addition to the abilities of students, tutors have the ability to:
76
* Create project groups, and add/remove students from them,
77
* View submissions to projects in the offering,
78
* Check out (with an external Subversion client) the part of a student or
79
group's Subversion repository which was submitted to a project in the

* Enrol a user in the offering as a student, if the system administrator has
82
allowed it (see ``tutors_can_enrol_students`` under
83
:ref:`policy configuration <ref-configuration-policy>`). This is
84
**disabled** by default,
85
* Create and edit worksheets for the offering, if the system administrator has
86
allowed it (see ``tutors_can_edit_worksheets`` under
87
:ref:`policy configuration <ref-configuration-policy>`). This is **enabled**
89
* View completion statistics for exercises in worksheets for the offering,
90
if the system administrator has allowed it (see
91
``tutors_can_edit_worksheets`` under :ref:`policy configuration
92
<ref-configuration-policy>`). This is **enabled** by default.
93
* Create and edit exercises *for any offering* (as exercises are not
94
offering-specific), if the system administrator has allowed it (see
95
``tutors_can_edit_worksheets`` under :ref:`policy configuration
96
<ref-configuration-policy>`). This is **enabled** by default.
101
The role of "lecturer" is offering-specific. Users may be enrolled in an
102
offering as "lecturer" by an admin.
104
In addition to the abilities of tutors (including any of their policy-specific
105
abilities, regardless of the policy setting), lecturers have the ability to:
