Transit: https://github.com/cognitect/transit-format https://github.com/cognitect/transit-format Transit has the following features: - self-describing - allows extension types on top of base types - strong value types + dynamic serialization - can transparently pass through data without consumer knowing about schema - has "repeated key" optimization in the encoder to allow compression in the stream - allows transparent binary encoding with msgpack - is stream-based, so processing can begin immediately unlike JSON which has enclosing {} This set of features basically allow transparent proxying to JSON as well, which is something that proto2/3 cannot do without updating the proxy.
