$document = new Document();
$document->addClass('order');

$properties = [
    'orderNumber' => 42,
    'itemCount'   => 3,
    'status'      => 'pending'
];
$document->setProperties($properties);

$entityOne = new Entity();
$entityOne->setClass([ 'items', 'collection' ])
    ->setRel([ 'http://x.io/rels/order-items' ])
    ->setHref('http://api.x.io/orders/42/items');

$entityTwoLink = new Link();
$entityTwoLink->setRel([ 'self' ])
    ->setHref('http://api.x.io/customers/pj123');

$entityTwo = new Entity();
$entityTwo->setClass([ 'info', 'customer' ])
    ->setRel([ 'http://x.io/rels/customer' ])
    ->setProperties([
        'customerId' => 'pj123',
        'name' => 'Peter Joseph'
    ])
    ->setLinks([ $entityTwoLink ]);

$entities = [ $entityOne, $entityTwo ];
$document->setEntities($entities);

$actionFieldOne = new Field();
$actionFieldOne->setName('orderNumber')
    ->setType('hidden')
    ->setValue('42');

$actionFieldTwo = new Field();
$actionFieldTwo->setName('productCode')
    ->setType('text');

$actionFieldThree = new Field();
$actionFieldThree->setName('quantity')

$actions = [ $actionOne ];
$document->setActions($actions);

$linkOne = new Link();
$linkOne->setRel([ 'self' ])
    ->setHref('http://api.x.io/orders/42');

$linkTwo = new Link();
$linkTwo->setRel([ 'previous' ])
    ->setHref('http://api.x.io/orders/41');

$linkThree = new Link();
$linkThree->setRel([ 'next' ])
    ->setHref('http://api.x.io/orders/43');
