Link:

1. 
http://linkeddata.informatik.hu-berlin.de/uridbg/index.php?url=http%3A%2F%2Flod.openlinksw.com%2Fdescribe%2F%3Furi%3Dhttp%253A%252F%252Fdbpedia.org%252Fresource%252FMichael_Jackson+&useragentheader=&acceptheader= 
-- URI Debugger output showing you what in <link/> and/or what you can 
extract via "Link:" response headers

As for the sole ODE option, that's kinda confusing as it isn't a 
coherent segue in the grand scheme of things for the human user per se. 
What I mean by that is this: we should also include the following links 
in the footer:

1. iSPARQL link that places you in the QBE or Advanced Mode tabs of our 
SPARQL Query Builder -- in this case you would see the DESCRIBE Query 
rather than having to processes the encoded URLs in <head/> <link/> or 
"Link:" response headers

2. PivotViewer links that places you either in the PivotViewer 
description page of the SPARQL query editor

3. Raw /sparql endpoint page that like #1 alleviates tedium of decoding 
the encoded SPARQL protocol URLs.

Then via 1-3 you end up with more human friendly routes to SPARQL behind 
the page.

Not worried about the prettiness etc..

Are 'Michael Jackson' Object ID and Object Representation Access Address 
distinct?   I already know that an HTTP GET against the Representation 
Address will return an EAV graph, once you loosen authentication 
requirements re. JSON representation :-)

BTW - can I assume this is the actual URL that you intended above re. 
access to JSON based graph representation:

?
