Representation of Data Object Description has new URL. Based on this 
response, the calling user agent *may* update its local relation between 
Data Object and the URL of the Resource that bears its Description 
(Representation). This is where an explicit "isDescribeBy" relation 
comes in handy re. Object Identifier association with Resource bearing 
its Description.

Representation of Data Object Description is no longer available here. I 
also have no clue as to if such a thing exists elsewhere. Based on this 
response,  the calling user agent *may* decide to discard all references 
to this Data Object.
