[Go-essp-tech] DRS hierarchy on disk

[stephen.pascoe at stfc.ac.uk]

To clarify I am only talking about CMIP5 datasets all arranged on disk
in the DRS hierarchy.

Hi Stephen

 

Bob or someone else can confirm, but  I think the issue is that ESG in
general is aiming at supporting more than just the DRS, so while
conforming to DRS is a given for CMIP5, it's not a given for all the
datasets that ESG may work with.

At the telco this Tuesday I was slightly surprised when someone (I think
Bob) asserted data is not likely to follow the DRS hierarchy on disk.
Although we know the disk layout can be mapped to DRS URLs in the web
server I thought our default position was that we would lay out the data
in the DRS hierarchy because it is the simplest solution.

 

This issue came up in a meeting with UKMO yesterday where they thought
there was a strong reason for using the DRS on disk so that fallback
positions like ftp follow a consistent structure.  I also learnt that
CMOR2 will output to the DRS hierarchy automatically.

 

Given this, why wouldn't we want to insist all datasets are stored on
disk in the DRS hierarchy?

 

Thanks,

Stephen.
