Thanks for the link!

Yes, EDN is a textual format intended to be human-readable. There is also a format called Transit used to serialise EDN elements. Unlike raw EDN, Transit is designed purely for program-to-program communication and drops human readability in favor of performance. It can encode data into either binary (MessagePack) or text (JSON), but in both cases, it preserves all EDN data types and originates from the Clojure language.
