When I say or hear "JSON Object", I assume the meaning is "Data of the sort that could be serialized and deserialized to JSON". In being so common, JSON implicitly specifies a type of data model, and most other similar serialization formats seem to be supersets of it. It also(at least to me) implies that the object is very dynamic. A json object is usually something self describing. You can add a key without any kind of protobuf type recompile step. Maybe you can even extend a protocol with nonstandard keys if you're careful about collisions. And it's meant to be sent over freeform channels like json or msgpack, and constrained (at most) by a schema. It's not quite technically correct, but I'm not sure what else carries the same common meaning. Perhaps "JSON-like data"?
