I’ve put together some preliminary thoughts that have been swimming around in my head for the past few months on workflow and BPM. Its hosted on our new REST-* work-group on the subject. While we still have some work to do on defining some of the initial media types and going beyond simple use cases, the design is very link driven. I’ve asked Tom Baeyerns and the jBPM team to help flush out the most common use cases users deal with. I also need a REST heavyweight lurking around to make sure we’re not introducing unRESTful designs. Anyways, Enjoy!
