I think we have all agreed to drop the word "production" as it infers
something that is very subjective. What I hope that we are nowdoing is
identifying types of Grids.
My proposal is that one type of Grid has the IGTF as trust anchor. As
the I in IGTF standard for International this is also a key property.
You have highlighted two other types of Grids, 'Service Grids' and
So we have now identified 5 different types Campus Grid, NGIs, Service
Grids, Desktop Grids and Multi-institutional International
Infrastructures for e-Science. The fact that we are using different
words to describe these suggests that they are subtly different
otherwise we could just use the word Grid.
