Using Safari, when I click on the link above I hit an authentication 
challenge [1]. The same problem with other browsers.

A few repeat questions:

1. Do you have a Data Object Identifier (Name Reference) for 'Michael 
Jackson' that's distinct from its actual Object Representation Address 
(Data Location Reference) with regards to the entity 'Michael Jackson' ?
2. Does the fidelity of the Object Graph that constitutes the Object 
Representation remain consistent across data representation formats?
3. Can I HTTP get against the Object Identifier for 'Michael Jackson' 
and receive a graph that describes 'Michael Jackson'?

The questions above are important since they define the HTTP based 
Linked Data concept and also lie at the core of all URLs published re. 
my demos. This is how we get to a more "Apples vs Apples" style of
