規格

[
  {
    "operation": "shift",
    "spec": {
      "ances": {
        "*": {
          "id": "result[&1].Building_id",
          "level": {
            "Building": {
              // if we matched all the way down here
              // then go back up and grab the "name" 
              // and write it's value to Building in
              // the result
              "@(2,name)": "result[&3].Building"
            },
            "Campus": {
              "@(2,name)": "result[&3].Campus"
            }
          }
        }
      }
    }
  }
]

更新了每個注釋的規范，其中不應對校園和建築物進行硬編碼

[
  {
    "operation": "shift",
    "spec": {
      "ances": {
        "*": {
          "id": "result[&1].Building_id",
          "level": {
            "*": {
              // if we matched all the way down here
              // then go back up and grab the "name" 
              // and write it's value to 
              // the result array, using the value of 
              //  level as the key
              "@(2,name)": "result[&3].&1"
            }
          }
        }
      }
    }
  }
