UU Courses and classes


Get ready for ultimate fun: spec change.
I talked about courses, authors, teachers, students,
payments, etc. with the boss today, and here are the results.

1. Student does not sign up to course. He signs up to class.
2. Any number of classes can be created for course.
3. Class admins define rules on who can sign up
4. Whoever created class is a teacher for that class.
5. Whoever created class is "class admin" by default
6. Class admins can add more teachers and more admins to it
7. Class admins can remove other class admins and teachers.
8. Authors define rules on who can create courses.
9. Each course has "default class" created for it, with author set
    to class admin and teacher by default.
10. Following class creation rules are available:
    - Fully open, accept donations: anyone can create class, if donation
of minimum
        is given to author, teacher has an option to show a stamp on his
course. Not
        giving a donation will show up on course as well.
    - Fully open, don't care about money: anyone can create class, no
donation absence
         marker will be shown.
    - Payment required, perpetual: Fixed payment is made, and class
exists indefinitely
    - Payment required, periodic: Flat rate payments for defined period
of time.
    - Payment required, percentage: Percentage of teacher's income from
this class
11. Following class sign-up rules are available:
    - Fully open, free: anyone can sign up, donation options same as above
    - Fully open, payment required: anyone paying fixed sum can sign up
    - Limited group, free: teacher signs up students himself
    - Limited group, payed: teacher signs up students himself, students
must pay
          (Normally this wouldn't make much sense: teacher can get payment
          through external means, but we can provide a way, just to make
it easier)
    - Moderated sign-up, free: anyone can put in a request to sign-up.
           decide who is accepted.
    - Moderated, payment requires: Same as above, but in order to put in
a request,
            Student has to pay fixed sum.
11. Concepts of open and closed server were revisited. In terms of payment
they will be equivalent (i.e. same author-teacher and teacher-student
possibilities). Difference will be that closed server will not have any
sort of
cross-linking or copying possibilities. I.E. one can only create courses
from their
own objects.

I think it sums things up. Now I need corresponding changes for db
schema and
for model diagrams.
Oh, and any comments/suggestions on the above :)
