[Pharo-users] Understanding ZnJSONReader mapping?

Hi - is there something I can read/study to get a bit more familiar with Json mapping? I have read the Pharo enterprise book (chapter 8). I’ve been using NeoJSONObject but then it occurred to me that maybe I could map better domain objects directly and simplify things. However it seems that the intent of mapping is just for simple things like an array of points - whereas if I have 15 different domain objects (albeit with a type key), then I’m wondering if I should just wrap json nodes on usage? In fact I’m wondering what the point of mapping is if it’s so simple - or maybe I’m missing an important concept? Tim Sent from my iPhone
