[LON-CAPA-users] Item-property problem

You can convert a CAPA problem and it will work, (Meaning
programatically defing an item list and randomizing it, and
progamatically defining a properties list, selecting a subset of them
and display them randomized, works, you can then make <stringresponse>
compare and grade correct and incorrect responses off a string list.)

<script> can do a heck of a lot.


However we have defined a XML markup of what a item / properties
problem should look like but it hasn't yet been implemented.

The design is


<itemresponse>
  <itemgroup>
    <item name="item1">
       .....
    </item>
    <item name="item2">
       .....
    </item>
    ....
  </itemgroup>
  <foilgroup>
    <foil name="foil1" value="item1">
      ...
    </foil>
    ....
  </foilgroup>
</itemresponse>

And then LON-capa would handle the randomization / foil selection,
creating a 2 tables of item to map onot each other and checking that
the mapping is correct/incorrect

Sound like a workable design?
