Augusto,

Looking into this matter further, this time going directly to the SPARQL 
endpoint which is basically the handler for the URLs used across 
<link/>, "Link:", and footer links.

1. http://linkeddata.uriburner.com/c/IA47SB -- query results
2. http://linkeddata.uriburner.com/c/IA47SH -- query text in the HTML 
editor associated with the sparql endpoint.

Now I need to find out why that isn't in the footer .
