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

The Facebook open graph API allows a public search, e.g.

https://graph.facebook.com/search?q=watermelon

The results returned may be statuses, videos, links, photos (and others?).

Each has a post id, e.g.

100000973592583_149321401769498

I wish to construct a URL to the post. For statuses, this seems to work:

http://www.facebook.com/profile.php?id=100000973592583&v=wall&story_fbid=149321401769498

However, for a link (or video or photo), that often works, but sometimes does not. For example, a link with id

45430244790_127287890653212

needed

http://www.facebook.com/posted.php?id=45430244790&share_id=127287890653212&comments=1#s127287890653212

Does someone have experience creating bulletproof links? Are there any docs on it?

Edit: Suppose I know the type as well (video, post, photo, link, ..)

Answer 1

Following FQL:

SELECT permalink
FROM stream
WHERE post_id="45430244790_127287890653212"

would return:

[
  {
    "permalink": "http://www.facebook.com/posted.php?id=45430244790&share_id=127287890653212&comments=1#s127287890653212"
  }
]
