JavaScript functions to wrap and unwrap a JSON object and its entire contents with KnockoutJS's ko.observable (and ko.observableArray). The odd nested-function layout here is a hangover from using requirejs. Cannibalize as needed.

ko wrapper

var ko_wrapper = function(ko) {
    var data = {};

	data.wrap = function(obj) {
		if (Object.prototype.toString.call(obj) == '[object Array]'
			|| Object.prototype.toString.call(obj) == '[object Object]') {
			for (var i in obj) {
				obj[i] = data.wrap(obj[i]);
			}
		}

		if (Object.prototype.toString.call(obj) == '[object Array]') {
			return ko.observableArray(obj);
		}
		else {
			return ko.observable(obj);
		}
	}

	data.unwrap = function(obj) {
		if (Object.prototype.toString.call(obj) == '[object Array]'
			|| Object.prototype.toString.call(obj) == '[object Object]') {
			for (var i in obj()) {
				obj[i] = data.unwrap(obj()[i]);
			}
		}

		if (typeof(value) === 'function') {
			return obj();
		}
		else {
			return obj;
		}
	}

	return data;
});
