<DIV><FONT face=Tahoma color=#0000ff size=2><SPAN class=522001910-20112009>This
is a problem for something like GridFTP where you 'see' the file system on the
server not the DRS hierarchy. <SPAN class=522001910-20112009>It's a
headache for applying security policy as presumably this is based on the DRS
structure. Some kind of mapping would need to be
maintained. </SPAN></SPAN></FONT></DIV>

DRS?</SPAN></FONT></DIV>

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

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.</SPAN></FONT><O:P></O:P></DIV></DIV>
