Two basic marking methods are possible:

In either marking method academic staff should be able to specify the number of marks to award if correct and the number (possibly negative) if wrong. Marks correct should range from 1 to 20 and marks incorrect from 0 to -10 with the addition of -0.25 and -0.5.

1. First split by a semicolon.
2. Element 0 = Label line colour (Flash-style hexadecimal values)
3. Element 1 = Width of line in pixels
4. Element 2 = Label background fill colour
5. Element 3 = Label font size
6. Element 4 = Label font colour
7. Element 5 = Label width in pixels (text)
8. Element 6 = Label height in pixels (text)
9. Element 7 = Label width in pixels (images)
10. Element 8 = Label height in pixels (images)
11. Element 9 = Mode: 1) single - each label is used once, 2) multiple - each label can used in an answer repeatedly.
12. Element 10 = Style (label or menu)
13. Element 11 - split by | character
    1. Split by $ character
       1. 0 = Label ID starting at zero.
       2. 1 = Instance of the label starting at zero (this is incremented by one when in repeating label mode)
       3. 2 = X coordinate of left of label (this coordinate being greater than 219 marks it as being a correct answer)
       4. 3 = Y coordinate of top of label
       5. 4 = Text (or image filename) of the label5 . If an image is used this is made of three parts split by ~
          1. Element 0 = filename
          2. Element 1 = Option when using images - original width of image in pixels
          6
          1. Element 2 = Option when using images - original height of image in pixels
14. Element 12 (onward) - split by $ character:
    1. 0 = ID of additional line
    2. 1 = Type (line, bobble or arrow)
    3. 2 = Start x coordinate
    4. 3 = Start y coordinate
    5. 4 = End x coordinate
    6. 5 = End y coordinate

The answers to all labels are stored in the 'user_answer' field in the relevant log table for a single question. The format is thus:
