Clojurians Log v2

hi! trying to figure out few things: 1. how can I define a model with a vector of children, e.g. something that describes value {:patients [{:name "Tom"}]} 2. how can i create an effect that inputs something under vector and outputs in there too? e.g. “when a patient name is “John”, add :last-name to “Doe”"

looking at https://github.com/domino-clj/domino-ui, example of vector of things + effects there would we great
