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

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.</SPAN></FONT><o:p></o:p></P></DIV>

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.</SPAN></FONT><o:p></o:p></P></DIV>
