When T2s were formally set up by WLCG, sites, known by their GOCDB site names, were grouped into federations which were associated with a country. This all made sense as we wanted someone responsible in each country to define the T2 topology and tell us the GOCDB names of the relevant institutes. Before that there were all sorts of sites declaring themselves as Tier2s. This topology is stored in REBUS.
Somewhere along the line someone assigned the same model to T1s (particle physicists like symmetry) so T1s also have a country/federation name/accounting name/ site name. The last two are the same in most cases, NL is the only T1 with >1 site.
The WLCG T1 name was supposed to start with the country code but a couple didn't follow the convention - NDGF understandably as they are a multi-country T1. I am not sure if this is used much apart from REBUS and Gstat. The T1 accounting reports don't use it and the experiments typically all have their own names for the T1s.
Anything automated that wants to refer to a site should use the GOCDB name as that bootstraps the BDII and Nagios.

I suspect the reference should now be
http://wlcg-rebus.cern.ch/apps/topology/
and if the relevant name is the accounting name then in fact RAL-LCG2 seems to be right. Maybe John Gordon understands what the different types of names mean but I don't :)
