In 2013 I was generating code from SDL definitions which could also be used for data validation during serialization/deserialization. I had plenty of “model” packages which were just SDL definitions, build config, and maybe some unit tests to validate the schema constraints. (Edit: SDL is “schema definition language” which was a schema definition tool written for Ion with definitions in Ion.) These were used in services and reactors which never touched raw Ion (at least not in any way different from Coral or BSF). Full disclosure, I spent a lot of my free time working on Ion, both the supported implementations as well as my own. The additional data types are worth it alone, imho. Having to use JSON for most things now I’m frustrated at what is “missing”.
