yes, it should be. If you see anything strange please let me know, but  
as far as I remember the documented has been updated every time there  
was a code change.

no, there is currently no relation between the DRS URLs and the  
dataset ids. You should use the dataset ids for now, and possibly in  
the future switch to the DRS ids when we (NCAR and PCMDI) include them  
in our metadata.

yes, that's how it is supposed to work...
