I believe the Accept parameter is intended only for the ability to list riak-native data. So to get riak parameters back as json, that's when you specify the Accept header. Regarding objects that you store it Riak, my experience has been that it returns the data back as you stored it. So based on the type that you specify when posting/putting the data, is the content type that you get back.
If I'm wrong, hopefully someone will correct me shortly :-) <http://www.loomlearning.com/> *Jonathan Langevin Systems Administrator Loom Inc.
