Take a look at the JsonView provided with FLOW3.

Don't use json in Fluid ;) Or use CDATA sections. Stuff inside CDATA is 
not parsed by Fluid.

Use the uri.action view helper to link to your json view.

It will output a json string from an object or array AFAIK, but that is 
more for inlining json inside a Fluid template.

This is not recommended as you modify the FLOW3 core classes, see above 
for some ideas how to do without.
