As some of you no doubt know, I'm returning from my elearning sabbatical to do the portfolio API for Moodle 2.0.
I've written up the basics of the spec here: http://docs.moodle.org/en/Development:Portfolio_API
It would be great to get some feedback on it as I think it's pretty overdue to start coding Please either post comments here, or on the discussion page in the docs.
That's great news, Penny. The portfolio is clearly in very good hands.
