    Default Answered: Modeling semi-complicated json structures

    Hello,

    I'm trying to read a json feed from yahoo weather. Seems like a pretty simple response, but I can't figure out the approach I should use to bring the data into my model. I was thinking jsonReader might be key, but it doesn't seem to support the format. Any help would be appreciated. Thanks. Here the response:

    Code:
    {
        "units": {
            "temperature": "F",
            "speed": "mph",
            "distance": "mi",
            "pressure": "in"
        },
        "location": {
            "location_id": "USLA0338",
            "city": "New Orleans",
            "state_abbreviation": "LA",
            "country_abbreviation": "US",
            "elevation": 13,
            "latitude": 29.97000000000000,
            "longitude": -90.09000000000000
        },
        "wind": {
            "speed": 10.00000000000000,
            "direction": "WNW"
        },
        "atmosphere": {
            "humidity": "67",
            "visibility": "10",
            "pressure": "30.39",
            "rising": "rising"
        },
        "url": "http:\/\/weather.yahoo.com\/forecast\/USLA0338.html",
        "logo": "http:\/\/l.yimg.com\/a\/i\/us\/nt\/ma\/ma_nws-we_1.gif",
        "astronomy": {
            "sunrise": "06:21",
            "sunset": "18:03"
        },
        "condition": {
            "text": "Fair",
            "code": "34",
            "image": "http:\/\/l.yimg.com\/a\/i\/us\/we\/52\/34.gif",
            "temperature": 62.00000000000000
        },
        "forecast": [{
            "day": "Today",
            "condition": "Sunny",
            "high_temperature": "72",
            "low_temperature": "52"
        }, {
            "day": "Tomorrow",
            "condition": "Mostly Sunny",
            "high_temperature": "70",
            "low_temperature": "62"
        }]
    }

  2. A Store needs an array so this response wouldn't work. You could use a store and get the forecasts but the other info wouldn't be part of any record.

    Thanks for the reply. Is there no way to massage the data prior to ingest? It seems like this would be something that would commonly need to be done.
