Wes McKinney commented on ARROW-692:
------------------------------------

[~bryanc] I'm working on this on the C++ side. I'm wishing I had put more 
thought into sharing abstractions between the JSON reader/writer and the binary 
IPC reader/writer, as it probably would have saved me a lot of time, but it's 
too late now. 

As a small detail, do you have any objection to nesting the dictionaries in the 
{{"schema"}} object? That turned out to make things simpler for me, but if it 
makes things harder on the Java side I can change the code. 

Otherwise I think we are aligned; I will add the integration test fixtures in a 
follow up patch and I reckon there could be a small round of format 
reconciliation over small issues (but maybe we'll get lucky!)
