hCard and a "target" hCard

Thanks Paul. Excellent comments.
I too am a big fan of "separation of concerns." However, if there is
no way for a robot application to determine in some automated way "who"
is "friends with" xxx then the separation of concerns buys me nothing.
> a URI is a great way to identify someone:
I'm afraid that URL doesn't do much for me in terms of understanding
who that person is. Here's a URL that's in a Flickr page that uses
/photos/24172116 at N08/
I think that you'll agree that URL's like this wouldn't be enough for a
robot application to create a social graph like this:
Alice is friends with Bob, who is a co-worker of Jim, who is neighbors
You make a very good point that we should not require hCard to be the
mechanism for identifying the source individual or the target
individual. The individual could be identified through a FOAF document
or OpenID or some other (standard) means.
Somehow there must be a mechanism for a robot application to consume an
*arbitrary document* that contains XFN and be able to determine:
- who is the source individual
- who is the target individual
Earlier I thought that perhaps the hCard for the source individual
could connect/point to the XFN. But now you have helped me realize
that the connection must come from the XFN: the XFN must connect/point
to the hCard or FOAF or OpenID that describes the source individual.
What do you think?
