I thought about this, but I was trying to separate issues pertaining to 
the result protocol itself (what data it contains, what is the 
underlyling data model) from issues pertaining to the wire format and 

It doesn't make sense to focus on the format before we understand the 
requirements for the data itself. I do agree that language-agnosticism 
probably implies a standard format, and human-readability is a 
requirement for me.

I'd like to understand that use case better. Can you give an example?
