Recall that a "representative hCard" identifies the person or
organization that represents the current web page.
Suppose that Alice has a web page on a social network. The web page
contains a representative hCard for Alice. On this web page Alice
invites her friends to add comments to her page. Bob is one of her
friends, and he adds this comment:
<p>Hi Alice. Nice page. I would like to introduce you to my friend <a
href="Sally.html" rel="friend">Sally</a> some time.</p>
Notice the use of XFN: >> rel="friend" <<
When a robot application encounters Alice's web page it will see the
representative hCard for Alice and it will see the XFN-bearing link.
Here's the relationship that the robot constructs:
Alice is friends with Sally
But that's completely wrong. Bob stated the relationship. The correct
Bob is friends with Sally
How would a robot avoid this error?
