 Ah. We do intend to use the Globus RLS, but the replica catalog itself
 has some problems for us: we currently store all our metadata in Oracle
 RDBMS we have some experience with LDAP, but are really not happy about
 storing our metadata in LDAP. We have started to put our efforts into
 using  the SRB - following Andy's suggestion - for local meta data
 storage and intend to use the replication location service as the federating
 catalog that will allow us to have 1 central location that users go to and
 then are re-directed elsewhere to local catalogs for more information
 (this GIGGLE thing). Of course, this depends on just how easy this is to
 integrate into our system. Our plea would be that this framework should
 impose a minimal overhead on setup/maintenance and new s/w over the
 existing system.

 Hello Ruth,
            Hmm. Better answer the remaining questions

 It's being used by some collaborators in BaBar. I'm not too sure that
 that tells us. It would be useful to be able to include any old copying
 application in the existing and new grid tools - SRB does allow that, I
 think that Globus allows that too.

 Oh yes! That would be very very useful for us. We will have dire need for
 the RLS in the future. It would be good if we could have a look-in at the
 design stages and understand how we can phase it into BaBar.
