attributes in facebook graph API - facebook

Question

In the facebook Graph API. the actual message of the object appears as "message": or "story":
Example:
{
"id": "148550335191249_236850319694583",
"from": {
"name": "Sinners Highway",
"category": "Musician/band",
"id": "148550335191249"
},
"story": "Sinners Highway edited their Biography and Band Interests.",
"story_tags": {
"0": [
{
"id": 148550335191249,
"name": "Sinners Highway",
"offset": 0,
"length": 15
}
]
},
"type": "status",
"created_time": "2011-09-02T21:49:50+0000",
"updated_time": "2011-09-02T21:49:50+0000",
"comments": {

}
},
and this one:
{

},
From what I can tell its completely random whether it is a message or a story.
Does anybody know where and when the story attribute is used and why?

Answer 1

Well from those two examples, the noticeable difference is that the story was an activity that was auto-posted about something the band did on facebook (editing their profile), whereas the message was something that someone has posted on the page wall.
