It was a sad day when LinkedIn retired the official resume generator. It would be nice if they could at least export some XML for anyone to run with, but I guess its all about locking users into your walled off service.
I read somewhere about an EU regulations coming which would force platforms to provide a way for their users to get their data back. Reimplementing the XML export would be a good way to (partially) comply ahead of time.
It's a shame that LinkedIn/Viadeo don't have builtin import/export to this format.
