Is your solution also about implementing complex processes that are likely to change on sophisticated business objects such as an insurance policy or claim?I think this is another false dichotomy. The most complicated business process could still incorporate GET, POST, PUT. Why on earth not?
I’ll happily agree that if you’re after a BPM-style solution, REST is not the first choice... clearly there’s no equivalent of BPEL for plain RESTful HTTP.
As it happens, I work on Restful Web Services for insurance, including policies and claims. So if JJ or anyone wants to work out some details, that collaboration could be educational for both of us.
Update: I created a wiki for this collaboration.
