Since JQuery has become so main stream, I've decided to be bold and take the jump.  I'm having a bit of an issue with Data objects.   I seriously love how easy it is to work with data in Spry, where I can pull XML or JSON and bind it to a Spry dataobject and go at things from there.  As a matter of what this is the main reason why I started using Spry because it was easy to work with data, and I did'nt have to come up 101 lines of javascript code. 

Anyways, are there any equalivent easy to work with libs, extensions, or plugs in or whatnot with Jquery?  What I'm looking for is a sort of JQuery Object Relational Mapping lib.  Think that sort of sums up with how Spry works with Data where you can Load XML or JSON and bind it to a DataObject and go at things from there..  You'd have to check out how Spry works with data to understand what I'm sort of looking for in an easy to use (fewer lines of code) javascript code.

Any help, ideas or pointers in the right direction much appreciated. 
Thank you.
