DataSource Utility: DataSource.Function

Your custom function can return arbitrary data, so use the appropriate schema plugin to normalize the data into a consistent format. Array data would use a DataSourceArraySchema plugin:

Whereas JSON data would use a DataSourceJSONSchema plugin:

YUI().use("datasource-function", "datasource-jsonschema", function(Y) {
    var myFunction = function(request) {
        return {
            "profile":{
                "current":160,
                "target":150
            },
            "reference": [
                {
                    ...
                },
                {
                    "category":"nutrition",
                    "type":"intake",
                    "fruit":[
                        {"name":"apple", "calories":70},
                        {"name":"banana", "calories":70},
                        {"name":"orange", "calories":90},
                    ],
                    "vegetables":[
                        {"name":"baked potato", "calories":150},
                        {"name":"broccoli", "calories":50},
                        {"name":"green beans", "calories":30}
                    ]
                }
            ],
            "program": [
                ...
            ]
        };
    },
    myDataSource = new Y.DataSource.Function({source:myFunction}),
    myCallback = {
        success: function(e){
            alert(e.response);
        },
        failure: function(e){
            alert("Could not retrieve data: " + e.error.message);
        }
    };

myDataSource.plug({fn: Y.Plugin.DataSourceJSONSchema, cfg: {
        schema: {
            resultListLocator: "reference[1].fruit",
            resultFields: ["name","calories"]
        }
    }});

myDataSource.sendRequest(null, myCallback);
});
