Jesse,

Which URI should I put in my foaf file [1][2]?

<http://purl.org/twc/id/person/TimLebo>
   a foaf:Person;
   owl:sameAs
              <http://graph.facebook.com/24407945#>,   # <-----
Facebook's URI for me!
              <http://graph.facebook.com/24407945>;     # <----- Or
should I omit the hash?

[1] https://github.com/timrdf/csv2rdf4lod-automation/blob/master/doc/instances/person/lebot.ttl
[2] my vanity is timothy.lebo



Why does <http://graph.facebook.com/24407945#> not resolve to anything,

bash-3.2$ curl -H 'Accept: text/turtle' http://graph.facebook.com/24407945#
_:error
	:error [
			:message "(#803) Some of the aliases you requested do not exist: 24407945#" ;
			:type "OAuthException" ] .

while <http://graph.facebook.com/24407945> resolves to something that
doesn't describe <http://graph.facebook.com/24407945>?

bash-3.2$ curl -H 'Accept: text/turtle' http://graph.facebook.com/24407945
@prefix user: <http://graph.facebook.com/schema/user#> .
</24407945#>
	user:id "24407945" ;
	user:name "Timothy Lebo" ;

Thanks,
Tim Lebo
