[Add xrootd list]
Hi Alvise,
As far as I can tell GFAL is just one of these "I'm the interface layer"
things, whose main purpose is theoretically to shield the user from the
fact that various file access protocols may be used behind the scenes.
It doesn't replace xrootd (dCache, rfio/Castor, ...) but simply interprets
the protocol from the filestring and loads the right (real) software behind
the scenes. It looks like it also accepts LFN's and GUID's in which case
it has to look things up in a catalog before using xrootd/dCache/rfio...
In ROOT (for example) the PluginManager plays more or less the same role.
Any real framework can provide such a thing relatively easily. (At CHEP Nobu
Katayama of Belle got in a nice joke about the complexity of the similar
layer that they have in their software.)
Anyway, maybe I've missed something about GFAL, so I've CC-d the xrootd list
in case someone else wants to add something.
