I am working with a relatively simple interoperability scenario where I must consume health facilities from a health facility registry api (which churns out json), transform them into a different format and post them through to the api of another system.

What makes this irritating is that I have to maintain a model of the health facility registry object which I have to unmarshall the json to, in order to transform it. I don't want these objects and I don't want to be unmarshalling anything. Thats extra code to maintain so, as ever, the simplicity catches up with you. I just want to transform the representation. With an xml source I have one xslt to maintain. With json I have both the code to unmarshall plus the code to transform.

I'll accept that JSON is a simple data design that makes easy programming tasks easier.

Would you give a concrete example of where JSON makes a difficult programming task more difficult please? And bonus points if you show how a more complex data design (e.g., XML) would not make the programming task more difficult.

And many bonus points if you can show (through some argument or a pointer to some research) how Michael's statement is always true, or at least true most of the time.
