6 - Run Local Query (Multiple File)

Assuming your current working directory is set to /home/<username>/workspace, run the following command:

UNITY_PACKAGES=/home/<username>/packages unity run example.jq -o out.json >> stdout.txt

Listing of /home/<username>/workspace/example.jq

jsoniq version "1.0";

import module namespace a = "http://dgms.io/modules/analytics";

import module namespace m = "http://acme.com/mymodel.jqm";

let $input := a:collection("http://acme.com/mydata.json")

return a:maximize({
    model: m:model#1,
    input: $input,
    objective: "cost",
    options: {
        solver: "minos"
    }
})
