[Esip-preserve] Identifiers Use Cases

[Ruth Duerr]

Hi Curt,

I took a look at your mods and made a few of my own.  I agree with you  
that a citation must fully identify the precise granule membership of  
the cited data set at the time the researcher downloaded the data.   
However, I think it is the citation that needs that, not the  
identifier for the data set.  I also think that, as you suggest in  
your use cases, the time of access is one possible mechanism for doing  
that (and that is probably the simplest mechanism from a citation  
standpoint though not necessarily from a user standpoint if for no  
other reason than it might have taken the user a month to download all  
the data they used and the data set may have undergone a whole host of  
updates over that time period).
