Aaron Birkland pointed out a severe, and unrecoverably problem with this proposal. For a versionable datastream, a new version is created for each property or content change. As such, to not make 10 versions with a datastream update, a proper transaction system, or methods that allow you to change all the properties in one invocation is nessesary. I will turn my thoughts to the transaction system, and hopefully return to this at a later dateFor that reason, a modifyDatastream method like in the current API is still required.
In this I will propose an alternative REST api to the one in the Fedora Documentation. It is based around the idea that every conceivable url should be gettable, and probably puttable. There should not be big methods with lots of parameters, but rather a bunch of small ones with very clear purpose. The interface should be usable without any documentation.
