A while back, I picked up on D’Arcy Norman’s complaint about how Moodle doesn’t export content to a standard. In a response to one of the comments on my post, I suggested that open source LMS communities like Moodle’s should encourage adopting institutions to consider the cost of exit as a selection criterion for their LMS. Doing so would encourage them to invest in export capabilities at the time when their commitment to the platform is high.
Well, as Chuck Severence notes, Oxford is considering doing exactly that with Sakai. Check out his post for some good notes on the pros and cons of various export strategies.
