How to construct a permalink for objects returned by Facebook's new Graph API?

Question

Hi,

Facebook Graph API allows getting Facebook objects like posts, videos etc in JSON from. Here is an example of a post: (taken from the documentation):

{
         "id": "719323658_129694190395214",
         "from": {
            "name": "Rabia Yalcinkaya",
            "id": "719323658"
         },
         "message": "COK MUHTESEM!!!",
         "picture": "http://external.ak.fbcdn.net/safe_image.php?d=41762b7121ee68754ebea48dee4568aa&w=130&h=130&url=http%3A%2F%2Fats.vimeo.com%2F192%2F882%2F19288238_200.jpg",
         "link": "http://vimeo.com/5646785",
         "source": "http://vimeo.com/moogaloop.swf?clip_id=5646785",
         "name": "Watermelon carving",
         "caption": "vimeo.com",
         "description": "Me carving a watermelon.",
         "icon": "http://static.ak.fbcdn.net/rsrc.php/z9XZ8/hash/976ulj6z.gif",
         "type": "video",
         "created_time": "2010-06-23T10:58:17+0000",
         "updated_time": "2010-06-23T10:58:17+0000",
         "likes": 1
      },

How does one construct a url which allows you to link back to the original video (or other types) on Bret's wall on Facebook? something in the form of

http://www.facebook.com/<USER_ID>/video/<VIDEO_ID>

Thanks, Boaz
