Thanks, Kingsley.

But I'm still at a loss for having my facebook URI being part of Linked Data...

(see within)

It's not my data space; it's Facebook's data space (as indicated by
the domain name up front and knowing that I'm not Mark).

Regardless of what URIs I make up by putting strings after that hash
(e.g., http://graph.facebook.com/24407945#this), NONE of them will be
described when I request them from Facebook; Facebook will just stare
back at me and say the same thing over and over again:

bash-3.2$ rapper -g -o ntriples http://graph.facebook.com/24407945
<http://graph.facebook.com/24407945#>
<http://graph.facebook.com/schema/user#id> "24407945" .
<http://graph.facebook.com/24407945#>
<http://graph.facebook.com/schema/user#name> "Timothy Lebo" .
<http://graph.facebook.com/24407945#>
<http://graph.facebook.com/schema/user#first_name> "Timothy" .
<http://graph.facebook.com/24407945#>
<http://graph.facebook.com/schema/user#last_name> "Lebo" .
<http://graph.facebook.com/24407945#>
<http://graph.facebook.com/schema/user#username> "timothy.lebo" .
<http://graph.facebook.com/24407945#>
<http://graph.facebook.com/schema/user#gender> "male" .
<http://graph.facebook.com/24407945#>
<http://graph.facebook.com/schema/user#locale> "en_US" .

Note that <http://graph.facebook.com/24407945#this> is NOT in
Facebook's response, so I fell into a dead end why trying to find out
about #this because there are no triples mentioning it).


By seeing:

<http://graph.facebook.com/24407945#>
<http://graph.facebook.com/schema/user#first_name> "Timothy" .

I'd say that

<http://purl.org/twc/id/person/TimLebo> owl:sameAs
<http://graph.facebook.com/24407945#>; a foaf:Person .

HOWEVER,

requesting <http://graph.facebook.com/24407945#> doesn't get me my first name .

Regards,
Tim
