Extensible Data Notation
The edn format is a text-serialization format often used with Clojure. Programs written in the Clojure language are represented in a superset of the edn format. Given its close wiring into the language, edn is an easy choice for reading and writing data. Although edn is most commonly seen in the Clojure community, implementations are available in other languages.[24]
Representing a product catalog in edn would take the following form:
| | [{:num 112 |
| | :dept :clothing |
| | :desc "V-Neck T-Shirt" |
| | :item-attributes { |
| | :sizing {:type :general :size :large} |
| | :color :blue |
| | :manufacturer-id 11250 |
| | :categories #{:mens :shirts :undershirts :vneck :premium}} |
| | :price #pricing/money "$55.35"} |
| | {:num 113 |
| | :dept :clothing |
