Hi all,
catching up with the e-mails, found this thread that went sideways...
I'm no expert, but in case anybody is still intersted what's the
difference between the RLS-es: there are many, but most notable in
my view is that the original Globus RLS uses Logical File Names
(LFN) as the unique file identifier, to which all the metadata and
replica locations are associated; while the EDG/LCG incarnation uses
GUIDs - Globally Unique Identifiers, the necessity for which traces
back to certain CERN-specific POOL software. So, unless you want to
meddle with those GUIDs (which are alphanumeric strings generated by
a specialized algorithm and are meant to be, well, globally unique),
don't use EDG/LCG RLS. I personally prefer GUID-based mappings, as
it allows for different LFNs to be associated with the same piece of
data, but it's just me.
Hope it helps,
Oxana
P.S. those Australian sites Maarten mentioned are not part of
NorduGrid, they just use NorduGrid's ARC middleware. The fact that I
use Windows does not make me a Microsoft employee :-) Similarly, the
fact that some sites use LCG-2 does not mean they are a part of the
LHC Computing Grid project. I've heard of people in Australia
playing with LCG-2, indeed, but I know no details.
