Rubric forms in Sakai

I am working on a set of forms for a well-researched set of rubrics for portfolio evaluation to donate to the http://openedpractices.org community library. There are 14 rubrics in the set, each dealing with a specific learning outcome. Every rubric has a set of 5-6 criteria that can be rated on a 0-4 scale. The rubrics contain descriptors for rating values 1-4 that describe under what conditions an evaluator should award each rating for each criteria and instructions to an evaluator encouraging them to award a "0" to anything that doesn't satisfy the descriptor for a rating of "1".

To implement these rubrics I am building OSP forms with a custom renderer. Here is how I plan to make them work:

• An evaluator will be presented with a table of criteria (rows) and rating values "1"-"4" (columns) for the rubric. Each cell of the table will include a clickable descriptor.
• The evaluator will also be presented text input fields for each criteria that would allow them to type in a rating value of 0-4. Each text input will be initialized with a "0" value.
• There will be a single text field for comments.
• When an evaluator clicks a descriptor in the table, the descriptor will be highlighted and the text input field will reflect the rating value for that table column.
• When an evaluator clicks a highlighted descriptor, the descriptor highlighting will be removed and the text input for that criteria will be set to "0".
• When an evaluator enters a text value for a rating, the value is immediately validated as a 0-5 value and the appropriate descriptor in the table is highlighted.
• If an evaluator decides not to enter a rating, she may delete the rating from the text input box. None of the fields are "required".

If you have any interest in providing some feedback into the behaviors of Sakai rubric forms, I'd love to hear about it.
