[Go-essp-tech] DOI target page CMIP5

[Karl Taylor]

Hi all,

Has it been decided how large a chunk of data is going to be assigned a 
DOI.  Will they be assigned at the DRS atomic dataset level?  Or the DRS 
"publication-level dataset" level? or what?   I guess the tradeoff is:

Larger chunks require fewer DOI's
Larger chunks mean that some files will be associated with multiple 
DOI's (when a single file in the chunk gets replaced, the chunk will 
have to be assigned a new DOI, so all the other files will now be 
associated with 2 DOI's).

We will have to provide a service so a user knows what data is 
associated with each DOI.  If a given subset of a chunk of data is 
associated with multiple DOI's, a reference to either DOI should point 
to the same (identical) subset of the data.

Is this confusing?

best regards,
Karl
