Dear Mr Foster,
I thank you for your clarification about the "convergence roadmap" and
for your very interesting report available on your mentioned blog about
the WS-RT specification advance.
As we oriented to a .NET-based WSRF implementation, we expected to
validate the connection with grids based on other frameworks (as GT4) in
a "second" step. We acknowledge that interoperability is essential -as
many people mentioned- for a durable efficiency and useability.
We will look at WS-RT specification if (when) this latter plays a bigger
role. For the moment, I believe that we will go on improving our tools
for database access on a grid because DAIS combined with WSRF seems to
our eyes to be a modular solution for an easier evolution (according to
