Yes, a guy told us that Amazon has an internal data format called ION. We googled for it, but didn't find it, so we assumed Amazon wants to keep it internal.

Not that you are under any obligation to care, but this will now be very annoying for Amazon employees.

"Oh, you need to call that service using Ion, not Json. No, the other Ion..."

Not to mention if they try to use it internally, then might end up with package name conflicts..
