[Go-essp-tech] DRS hierarchy on disk

[bryan.lawrence at stfc.ac.uk]

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.

Subject: [Go-essp-tech] DRS hierarchy on disk

 

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.
