Ext.define('ExtMVC.model.Book',{
extend: 'Ext.data.Model',
fields: [

// The first needs mapping, the others are very basic
{name: 'Author', mapping: 'ItemAttributes > Author'},
'Title',
'Manufacturer',
'ProductGroup'
]
});

model: 'ExtMVC.model.Book',
autoLoad: true,
proxy: {
// load using HTTP
type: 'ajax',
url: 'data/sheldon.xml',
// the return will be XML, so lets set up a reader

type: 'xml',
// records will have an "Item" tag
record: 'Item',
idProperty: 'ASIN',
