Есть ли sdk/lib для анализа данных gdata (json), возвращаемых Google Contact API v3?

В настоящее время я получаю доступ к контактам Google через API GoogleContact v3. Я использую следующую команду:

"https://www.google.com/m8/feeds/contacts/default/full?access_token=" + token.access_token + "&alt=json&v=3&q=Susan"

Он возвращает мне ответ структуры json в формате gdata.

В настоящее время у меня есть ответ и я создаю свой собственный метод для доступа к каждому файлу. Есть ли уже определенная библиотека, которая преобразует это в более читаемый объект?

Например, я предполагаю, что «gd $ name» — это представление данных Google для имени. Есть ли способ преобразовать его в контактный объект gData, который дает мне поле имени без необходимости писать собственный парсер gData?

Спасибо, Дерек.
