[erlang-questions] No JSON/MAPS interoperability in 17.0?

Erlang/OTP won't include a Json library if there isn't a specific need 
for it from another OTP library. And, even if it had, it would be a 
tough sell.

There is currently no such need. Also, the Erlang community already has 
a couple of implementations. We have no wish to increase our maintenance 
with something that has already been solved.

With Json becoming so prevalent (web services, browsers, Mongodb, etc), I think it is really surpassing XML as a common data interoperability format. It must have been on the table at one point or it wouldn’t have appeared in Joe’s book. Why did it not make it into the release? I think someone indicated that it really didn’t belong in the maps module and I can kind of see that. But why not just put it in a “json” module? Regards, Chuck
