Ok Julia,
Rob, for the topology, what we would need:
final goal:
- we will ask WLCG to have the xroot service become a real service in OSG and GOCDB. Then we ask sites to declare their xroot servers. In this way the xroot service will become like an SRM, or a GRIDFTP.
step-by-step:
- since I know that "politics" on this is slow, and then sites don't publish correctly, we will need in the meanwhile a first list of xroot servers.
- you send me a list with some basic structure, e.g. SiteName (please check AGIS for this http://atlas-agis-dev.cern.ch/agis/site/table_view/), and root:endpoint:port/path
- we include them in AGIS, and we publish them so that people can see them
- we create a way to declare them in AGIS for the future.
- when the step of having the xroot service in GOCDB/OIM is done and sites have published the services then AGIS collects them from there and automatically associate them to the right site.
Ok?
